Yes, Just because the power supply can produce up to 65 watts does not mean it's running at 65 watts. That would be very hot on the power supply end and highly unlikely these electronic power supplies always adjust to suit the load. So if the load was 15 watts it would probably be using 15 watts from the grid and so on
A company called Zens does the same exact thing, they released a few years ago. 2 devices at 15W and they have a clear version. Active fan cooling as well. You can also buy an apple watch adaptor to make it 3
Nomad also used to sell a Freepower charging station back in 2020, although nowadays I think they've leaned back on their normal base stations that have apple watch mounts/chargers built in.
@@craigchatterton4164 I wonder if it is possible to make something like this DIY. I'd love to set up a large section of my desk with wireless charging pads under the wood. My dream build is to be able to place my phone anywhere on the right-hand side of my desk and it just charges. I feel like buying multiple single coil pads could cause interference with each other and possibly be a hazard? But not sure.
@@mavis6935 You're talking about a massive area on your desk? Like feet x feet? You'd need a LOT of copper windings to set that up. Notice how close together they are in the Tesla charger, so they can handle just about any place someone sticks their phone. If we talk in terms of the Tesla wireless charger: If you wanted to set up an area that was 4x3 wireless chargers big, that 30x12 = 360 windings! That's a LOT of work winding copper. Even a 2x2 would be 120 windings. Whew! You might be better off just buying the Tesla Chargers and fitting them underneath your desk. 2x2 is $1,200, so that's the EXPENSIVE option definitely! lol
Freepower already sold a similar device through NOMAD but it was called Base Station Pro over there. The old one could only charge two devices at a time and there was a long history of firmware updates as they were getting the bugs out. I previously had the NOMAD one but it occasionally would not charge my phone. (Which was a bit upsetting to wake up with an uncharged phone.) I now either charge wired or with an Apple certified Magsafe pad to be sure I always have my phone ready when I wake up.
I don't get why people use wireless charging for phones anyways. For gaming mouse pads it makes sense. For phones it does not. Ain't nobody got time for 15watts max rated charging...
@@EikottXD Convinience when you are not in a hurry, I use one to charge my phone overnight it's a one step process vs finding the end of the cable, plugging it and putting the phone down. Same thing during the day while I work I have another wireless charger that I use if the battery gets low. Of course if I need to go somewhere and my phone needs charging I'll use the fast charger.
@@EikottXD Yeah, what an excellent way to send those pesky microwave transmissions directly into the center of your hands cells. Of coarse trusting the peeps who sell this trash to actually warn of dangers (or even BETTER incorporate safety into the tech to begin with) is always a recipe for a win (for the salesperson hah). Even people who were relative EXPERTS in the field of electromedicine such as bob beck and hulda clark STILL died of cancer from what they were doing, THIS is a whole other level!
@@EikottXD I used to think the same, that it was a pointless gimmick, but it's actually kinda convenient in the right situations. Like the other guy said any time I really need to make sure my device charges quick or full before doing something I plug it into one of my good 30-65w GaN chargers. But for my bedside table I plop my phone or earbuds on that because I don't care how long it takes, I'm going to sleep for 6hours at least so it's fine and it makes everything a lot cleaner and easier not dealing with wires.. also if my phone is dying it helps me finally go to sleep because I can't just plug it in and keep using it, forcing a better habit. I also have a wireless pad on my desk, for basically the same reason, I'll use discord and everything else on my pc while I'm there, so idc if it's slower. And there's one built into my car, which I like because it holds the phone in place too while I'm driving and keeps it charged up as I use wireless android auto. But if my phone is low then I'll actually plug it in.
I prefer having both....(wired usb plugs AND wireless charging)! Luckily it's cheap AND easy! Just wire in usbA & usbC jacks into the wireless base and add another voltage regulator.
This is really cool. My friends have a wireless charging pad with a clear top similar to this. It's super handy when we're over and need to charge any phones or multiple at the same time.
I think the reason Apple did not launch it was because it also had to work with the Apple Watch (which I would love to see yo try and maybe make a short of it later) and they announced a non working prototype which was way thinner and heat dissipation in a device as thin as they wanted would not have been possible.
I think the actual reason they didn't is magsafe. 1.They decided to make their phone charge wirelessly and 2. Wanted to get royalties liks they xo now from MFA program So ghey decided to use mag safe so they can get royalties from manufacturers.
Apple stopped development because they realised that the way the Tesla charger works is the only way to realistically do it with today's technology, and it still isn't universal across the surface and it has the same issues with phones/devices having to be positioned in certain ways to start charging, apples concept was a device that could charge multiple things positioned anywhere on the surface with zero adjustment necessary, which they found isn't realistically possible
There ARE wireless chargers for electric vehicles, Jerry. They are still being trialed in Europe, but they are shockingly efficient. There's a video from Byorn Nyland where he showed that one company's product that's already being installed in curb-side charging in some cities is about 95% efficient, which is about the same efficiency as wired fast-charging.
I’m unsure whether that 95% number is trustworthy until it gets into the hands of an independent tester. Companies have sometimes fudged their data before…
I’ve seen some wireless EV chargers that peaked that high, but it’s in very specific test environments. They raise the charging coil up to touch the vehicle while it’s parked. And your car must be parked dead center with the charger. They talked about adding x-y movement too so the coil moves to match the vehicle in a future version. But a lot of the wireless charging happening on roads are completely awful efficiency.
@@coredumperror yeah, I’m confounding different wireless charging solutions. A department of energy lab got 20kW from a prototype spaced 6” apart. Witricity has a 7kW version, but they just have marketing promises that mention it “works” from misalignment or high ground clearance. It’s been a few years since I read about the one that lifts into place, but can’t find anything on it now. Which generally isn’t a good sign about the company still being around lol.
Not to diminish Tesla's brilliant work, but Martin Soljacic was the one who pioneered near-field coupling in 2006. Tesla's coil used resonant coupling but in the far field at tens of kV, where the losses and "lightning everywhere" made it impractical for things like charging phones.
There is wireless charging for vehicles... in Europe. It uses magnetic resonance instead of the standard induction you have with qi charging. The Fully Charged Show covered that a while back.
@@Eratas1 Phones built after 2017 should be able to support Qi resonance charging, but there are pros and cons with resonance charging. Normal inductive charging is about 60-80% efficient while magnetic resonance is below 30%. Additionally resonance charging requires more complex circuitry and can produce a lot more electromagnetic interference in the environment. The main benefit for magnetic resonance is it can transfer power over a much further range which is why phones still have it as an option and also could be why cars use it.
The problem with AirPower wasn't getting the coils in there, it was having 2 different standrads with Qi and the Apple Watch charger causing so much EMI and heat that that the pads would literally burn down in Apples labs.
Nah, the problem is they are incapable of making innovations so they wait till someone else does it and rip it off. The only real innovation they made in the last years was the efficiency of the overpriced M2 processor while retaining it's excellent performance.
@ Ok, tell me one of their "innovations" that isn't making it harder to fix the phone? Every larger "feature" they brought in the last few years was on andorid years ago.
Thanks for the tear down. 65watts is not going poof when a device is partially using it though. It would only draw 65w when maximum devices are connected. This can be measured using a plugin energy meter.
apple also had an array of IC chips on the device that interacted with the thing it was charging to play the animation also they needed different coils due to the apple watch charging system being proprietaty. any company can lay them out in a grid array like this its been done before airpower was a concept
I don't know why, but I died a little in my soul, every time you went to scratch up the hardware.. I do think a transparent version of this would be awesome! And instead of black, it should be colored Red so it goes faster.
They do have wireless charging for EVs in Europe and they are actually pretty efficient. Bjorn Nyland did a test on one and it was more efficient than a plug in charger.
I saw the video a year ago. There is no way that wireless charging is more efficient. The person Bjørn interviewed is a salesperson. Wireless charging always adds more switching and transforming power.
Wireless chargers are a waste of power and copper, in my opinion. You can't really use your phone while charging, and the waste heat degrades the battery faster
@@sharky07xy The test they did in the video showed 2 things 1. Wireless charging can be pretty efficient done properlly 2. The conductive charger they tested had horrible efficiency Yes the sales person probably made sure to used a cheap transformer so his wireless charger looked better, but it still was impressive anyway. Sure, for the same price a wireless charger while never be as efficient, I'm just saying that it's possible to make an efficient one and that it already exists.
The issue Apple had with AirPower is the small coils required for the Apple Watch. Mixing them with the larger ones required for all other QI devices is where they ran into heat issues. Apple could have definitely have made this but since they didn’t want to leave the Apple Watch unsupported (and also didn’t want to switch it to QI) they decided to cancel it.
@@Johnnygga I highly doubt it. There are a bunch of Android phones that can charge at 65W. So 65W spread over such a large area and with tons of thermal mass should be fine… I think.
Once you plug the charger into the wall, its probably going to sit there on a desk, bench, or nightstand untouched. So you wouldn't have to replace the cable like you would doing wired charging. Kind of like how a nightstand light doesn't need to cord replaced.
@@jamieclaudeo8107 Yeah that's kind of a fair point, it would be nice to see them put a port on the back of the thing though, it's really not much work and would cost them pennies. The cable looks quite long too, it would be nice to be able to use a shorter one if you don't need the length. It's just dumb to have fixed usb cables on things these days even if they won't see much wear.
Hey, electronics engineers, any reason these were with circular coils rather than squares (to maximize area)? Is it problematic with the magnetic field it creates, or just harder to control?
It’s more a question of efficiency, you want the flow of current to match the direction of the coil on the phone’s coil; squares would have little current matching up directionally, it would still charge, just much slower
The flux generated by a coil is proportional to the Area and the cost of the coil is proportional to the perimeter. The circle shape has a better perimeter per unit area compared to the square shape
There are a variety of reasons but the main ones are efficiency and ease of manufacturing. A circular coil produces a magnetic field that is evenly/uniformly distributed in all directions, making it more efficient at transferring power to a device placed anywhere on the charging pad. A square coil would produce a magnetic field that is stronger near the corners and weaker along the edges. This non-uniform field distribution would lead to less efficient power transfer and result in a slower charging process or require the user to carefully position the device on the pad to ensure it is charging.
not an EE, but I think it has to do with the even distribution of the field produced by a circular coil vs a square would produce uneven fields concentrated in the corners. The receivers would also be circular so squares wouldn’t match up as much.
Got curious seeing a big wireless charger in my recommendations - so I clicked on it. Not a minute yet and the first thing that happened was scratching the item. I am reminded this is JerryRig.
MagSafe is so much better than using a pad to charge. You have to line things up, if there not oriented to the pad correctly you lose efficiency. With MagSafe you don’t have any of those problems and you can use your device while charging. It really is a perfect design.
Hey Zack, I'm pretty sure the charger only pulls the amount of power needed for the device. The coils are intelligently turned on to full power only when a device is present. 😁😁😁
Xiaomi made one wireless charging pad with the exact same 3 device support years ago for less than $50 with 20w to 3 device simultaneously, this seems like a novelty item more than anything else.
In my opinion the efficiency loss still outweighs the convenience. Until someone finds a solution to the efficiency (which I doubt will ever happen) I will stay cables only until they remove them.
Thanks for watching, Tim Cook 😂😂 Nice start to the video. A $300 pricetag is pretty crazy though, even with the coils embedded into it coming out to $10 each. One of major points when making something, is to ask whether the price is accessible. For most people, definitely not, considering most won't even spend more than that on their smartphones and opt for a Samsung Galaxy A-series device or other low-mid spec android. Having a charger priced equally to the actual thing you want to charge? Yeah, I don't see the success. Even pricing it at 1/3 to 1/4 of the price of a high end smartphone makes me step back and think. It's not only here where I have that issue either, but also for example with Apple themselves, and the exorbitent prices they charge for iPad folio keyboards these days. $200-300 for a case for an ipad that costs the same amount - it's like WHY??? The iPad was supposed to be the budget option, but then you make an accessory which makes it anything but budget friendly. I just don't see this being profitable for Tesla right now with that said. Especially given that Elon surely paid hundreds of millions on R&D for this, including creating the tooling required to actually mass-produce it. Maybe I'll be surprised though and it becomes huge.
There is no money to be made in the low-cost market for western brands. For what happens if you try to compete there, look at all the failed German consumer electronics companies. Appealing to people just wanting to buy the cheapest shit is just a race down a bottomless pit.
Dude Hundreds of millions on R&D for this? A separate company with the technology made it for them. It is purely meant as a novelty and collectors item. Also, most low to mid spec android phones do not have wireless charging. You are just not in the target audience. Also, did it ever occur to you that companies need to make money on things? Even if the coils were 10 dollar each, they are free to just charge whatever price they want so that they can turn a profit. The price of an entire car isnt the sum of all the parts together ..
@@neofaktion dude. Apple couldn’t figure it out with their trillions of dollars. Also, tooling manufacturing machines isn’t anywhere close to as cheap as you think it is. Companies commonly offset those costs by making it as accessible as possible to as many people as possible. And you’re way off the mark by saying I’m not the target audience. It’s hardly a designer item, nor is it limited edition being made purely for the obscenely rich. If it were, it’d be priced much higher than $300. Tesla are targeting anyone who has a wireless capable device. Maybe not with this specific iteration but at the very least as a working prototype to gauge the market
@@grahamb7947 Apple couldn't figure it out due to them wanting to combine their proprietary Apple Watch charging tech, and regular Qi wireless. If they were targeting anyone who has a wireless capable device, then they would price it accordingly. In this case, they simply collaborated with a company who already had the tech.
That’s great to see the teardown but you didn’t compare it to any other wireless chargers, it would’ve been nice to know what it’s actually putting out other than just the “15” like does it work any better than the other wireless chargers on the market, how fast does it charge compared to other wireless chargers? is it worth a 300 price tag??
Nope apple will never do such nonsense! Apple will develop something that is actually smart and can communicate with the charging devices and even send alert if possible so you are wrong
@@treeoflife7151 aren't there renders and prototypes clearly showing the direction apple wants to take with it's wireless charging pad? It's functioning, but in the long run it's going to bring out lots of issues, that's why they cancelled it
great tear-down, but so painful to see you scratch such a well made and great surface finish. Next time, scratch somewhere where it doesn't show. Looking forward to the next video, great job.
6:03 the Great Pyramids were not built by the Egyptians, they were found. They had been used previously as a worldwide wireless charger tens of thousands of years ago before even being discovered by ancient Egyptians.
In Belarus public buses charging battery same way , they have charging points at each bus stop. So when bust stop to let passengers to leave a bus or get inside, the battery charges same time while bus at bus stop .
Nice teardown! Couple of corrections... just because the power supply is capable of delivering 65 watts does not mean that it is always delivering 65 watts with just one device charging at 15 watts. Assuming 60% efficiency one device at 15 watts should require the power supply to deliver 25 watts, so the 65 watt capability is there for multiple device charging. In addition, the adhesive between the coils almost certainly does not provide critical electrical insulation. Each coil will have clear insulation coating the wires because it is necessary to insulate each turn of the coil from its neighboring turns in order to function as an AC transformer (coil on the charger is the "primary", coil insude the charged device is the "secondary"). Each inactive coil must be kept as an open circuit in order to not interfere with the inductive coupling of the active coils, so the charger must be doing some logic to identify the coil with the best coupling to the device. Otherwise, great job!
Zens did that a while ago with the WLC UNIV LIBERTY 16 GLASS (even transparent) for like 200 bucks! so nothing really new, still cool to see this trend starting up....
It did not seem like 30 coils really though once you started lifting them up. I wonder if some solder connections were for thermistors or something? Neat look inside!

Mesmerizing view inside indeed. A transparent version would rock!
Same with clear cell phone battery covers for cell phones. I have the spigen zero one case. It's nice, but fake
A company called Zens does the same exact thing, they released a few years ago. 2 devices at 15W and they have a clear version. Active fan cooling as well. You can also buy an apple watch adaptor to make it 3
Nomad also used to sell a Freepower charging station back in 2020, although nowadays I think they've leaned back on their normal base stations that have apple watch mounts/chargers built in.
"Zens Liberty Built-in Wireless Charger Glass" for anyone curious.
Liberty Charger has half as many coils but is priced higher than Tesla's.
@@craigchatterton4164 I wonder if it is possible to make something like this DIY. I'd love to set up a large section of my desk with wireless charging pads under the wood. My dream build is to be able to place my phone anywhere on the right-hand side of my desk and it just charges. I feel like buying multiple single coil pads could cause interference with each other and possibly be a hazard? But not sure.
@@mavis6935 You're talking about a massive area on your desk? Like feet x feet? You'd need a LOT of copper windings to set that up. Notice how close together they are in the Tesla charger, so they can handle just about any place someone sticks their phone. If we talk in terms of the Tesla wireless charger: If you wanted to set up an area that was 4x3 wireless chargers big, that 30x12 = 360 windings! That's a LOT of work winding copper. Even a 2x2 would be 120 windings. Whew! You might be better off just buying the Tesla Chargers and fitting them underneath your desk. 2x2 is $1,200, so that's the EXPENSIVE option definitely! lol
'Thanks for watching Tim Cook ' best line😂
i am wondering if potting them in non conducting epoxy would help to show off the copper coils while also providing a thermal heat synch.
Heat Sink. As in heat going down the sink
The perfect blend of science and art. Wow, it's beautiful.
Zack, I'm all for transparency! That is a fantastic charger, really love the design.
0:30 someone at the factory got a little to happy
Me searching for a 300$ phone...
Tesla - u want a 300$ charger ???
Freepower already sold a similar device through NOMAD but it was called Base Station Pro over there. The old one could only charge two devices at a time and there was a long history of firmware updates as they were getting the bugs out. I previously had the NOMAD one but it occasionally would not charge my phone. (Which was a bit upsetting to wake up with an uncharged phone.) I now either charge wired or with an Apple certified Magsafe pad to be sure I always have my phone ready when I wake up.
I don't get why people use wireless charging for phones anyways. For gaming mouse pads it makes sense. For phones it does not. Ain't nobody got time for 15watts max rated charging...
@@EikottXD Convinience when you are not in a hurry, I use one to charge my phone overnight it's a one step process vs finding the end of the cable, plugging it and putting the phone down.
Same thing during the day while I work I have another wireless charger that I use if the battery gets low.
Of course if I need to go somewhere and my phone needs charging I'll use the fast charger.
@@EikottXD Yeah, what an excellent way to send those pesky microwave transmissions directly into the center of your hands cells. Of coarse trusting the peeps who sell this trash to actually warn of dangers (or even BETTER incorporate safety into the tech to begin with) is always a recipe for a win (for the salesperson hah). Even people who were relative EXPERTS in the field of electromedicine such as bob beck and hulda clark STILL died of cancer from what they were doing, THIS is a whole other level!
@@EikottXD I used to think the same, that it was a pointless gimmick, but it's actually kinda convenient in the right situations. Like the other guy said any time I really need to make sure my device charges quick or full before doing something I plug it into one of my good 30-65w GaN chargers. But for my bedside table I plop my phone or earbuds on that because I don't care how long it takes, I'm going to sleep for 6hours at least so it's fine and it makes everything a lot cleaner and easier not dealing with wires.. also if my phone is dying it helps me finally go to sleep because I can't just plug it in and keep using it, forcing a better habit.
I also have a wireless pad on my desk, for basically the same reason, I'll use discord and everything else on my pc while I'm there, so idc if it's slower. And there's one built into my car, which I like because it holds the phone in place too while I'm driving and keeps it charged up as I use wireless android auto. But if my phone is low then I'll actually plug it in.
I prefer having both....(wired usb plugs AND wireless charging)!
Luckily it's cheap AND easy! Just wire in usbA & usbC jacks into the wireless base and add another voltage regulator.
This is really cool. My friends have a wireless charging pad with a clear top similar to this. It's super handy when we're over and need to charge any phones or multiple at the same time.
"still aint paying 7 dollars for twitter though"
I think the reason Apple did not launch it was because it also had to work with the Apple Watch (which I would love to see yo try and maybe make a short of it later) and they announced a non working prototype which was way thinner and heat dissipation in a device as thin as they wanted would not have been possible.
Also I've heard that the coils were interfering with each other.
A thinner wireless charger literally doesn't have any benefits aside from aesthetics lol, this is just Apple being Apple 😂
I think the actual reason they didn't is magsafe.
1.They decided to make their phone charge wirelessly and
2. Wanted to get royalties liks they xo now from MFA program
So ghey decided to use mag safe so they can get royalties from manufacturers.
@@n27272except they still support normal wireless charging..
Apple stopped development because they realised that the way the Tesla charger works is the only way to realistically do it with today's technology, and it still isn't universal across the surface and it has the same issues with phones/devices having to be positioned in certain ways to start charging, apples concept was a device that could charge multiple things positioned anywhere on the surface with zero adjustment necessary, which they found isn't realistically possible
Your jibes at Apple are always so funny and accurate! 😂
Yeah! Jerry, Elon should make a transparent version! Period!
I agree with the transparent top. That would look really cool.
There ARE wireless chargers for electric vehicles, Jerry. They are still being trialed in Europe, but they are shockingly efficient. There's a video from Byorn Nyland where he showed that one company's product that's already being installed in curb-side charging in some cities is about 95% efficient, which is about the same efficiency as wired fast-charging.
I’m unsure whether that 95% number is trustworthy until it gets into the hands of an independent tester. Companies have sometimes fudged their data before…
I’ve seen some wireless EV chargers that peaked that high, but it’s in very specific test environments. They raise the charging coil up to touch the vehicle while it’s parked. And your car must be parked dead center with the charger. They talked about adding x-y movement too so the coil moves to match the vehicle in a future version.
But a lot of the wireless charging happening on roads are completely awful efficiency.
95%? I think not, especially if these are government numbers who are pushing green agenda. Independent testing is required to verify such numbers.
@@crelliseng iirc you do have to park *very* precisely with this charger, but I don't believe it rises after the car is in position.
@@coredumperror yeah, I’m confounding different wireless charging solutions. A department of energy lab got 20kW from a prototype spaced 6” apart. Witricity has a 7kW version, but they just have marketing promises that mention it “works” from misalignment or high ground clearance. It’s been a few years since I read about the one that lifts into place, but can’t find anything on it now. Which generally isn’t a good sign about the company still being around lol.
Transparent version would be something different, next level 😮
it would be but you'll have to sell your soul in the after life market.
Transparent would be pretty epic!
Not to diminish Tesla's brilliant work, but Martin Soljacic was the one who pioneered near-field coupling in 2006. Tesla's coil used resonant coupling but in the far field at tens of kV, where the losses and "lightning everywhere" made it impractical for things like charging phones.
There is wireless charging for vehicles... in Europe. It uses magnetic resonance instead of the standard induction you have with qi charging. The Fully Charged Show covered that a while back.
Why phones not use magnetic resonance charging?
@@Eratas1 Phones built after 2017 should be able to support Qi resonance charging, but there are pros and cons with resonance charging. Normal inductive charging is about 60-80% efficient while magnetic resonance is below 30%. Additionally resonance charging requires more complex circuitry and can produce a lot more electromagnetic interference in the environment. The main benefit for magnetic resonance is it can transfer power over a much further range which is why phones still have it as an option and also could be why cars use it.
Hurts every time Jerry scraps the charger with the blade.

@@devstorm5416 🤓
It hurts you to see paint come off? Life is going to be cruel to you...
The problem with AirPower wasn't getting the coils in there, it was having 2 different standrads with Qi and the Apple Watch charger causing so much EMI and heat that that the pads would literally burn down in Apples labs.
Imagine expecting a supposed tech reviewer to actually understanding this simple difference rather than just rage bait the even less informed audience
Nah, the problem is they are incapable of making innovations so they wait till someone else does it and rip it off. The only real innovation they made in the last years was the efficiency of the overpriced M2 processor while retaining it's excellent performance.
@@Mari0o0o you sound like a apple fanboy

Such an amazing calming voice. You could convince me to buy anything! Thank you for bringing your positive energy to TH-cam
Thanks for the tear down. 65watts is not going poof when a device is partially using it though. It would only draw 65w when maximum devices are connected. This can be measured using a plugin energy meter.
i agree a transparent version would be epic. looks so cool
Nice. I think the other reason Apple stopped trying was because they wanted it to charge the watch, too.
You need to have a piece of acrylic (or glass if possible) made for this thing! It's too cool looking to keep hidden
So beautiful, thank you Jerry and thank you TESLA!!!;)
"Still ain't dropping $7 for Twitter though" LOL
Only downside is the cable goes inside the device and is therefore non-replaceable. A usb-C port would've been the best
It's replaceable if you have a screwdriver and a soldering iron. But still, a USB C port so anyone could do it would have been best.
Yeah and then the port falls and you have to replace it. Hard wired is better
I don’t think it’s meant to be moved around too much, so that shouldn’t be a huge issue.
Its also handy if u want a longer or shorter cable
@@mjc0961 i think thats modification not replacing in my understanding and warrenty voiding.
apple also had an array of IC chips on the device that interacted with the thing it was charging to play the animation also they needed different coils due to the apple watch charging system being proprietaty. any company can lay them out in a grid array like this its been done before airpower was a concept
I don't know why, but I died a little in my soul, every time you went to scratch up the hardware..
I do think a transparent version of this would be awesome! And instead of black, it should be colored Red so it goes faster.
Fun fact, There are actually wireless chargers for electric vehicles. Momentum Dynamics is currently charging bus fleets and taxis overseas.
that's quite a distance
GONNA BE AWESOME WGEN JERRY DO THE DEBRAND top layer for that copper look 👌🏼
Thanks Jerry always educating and entertaining.
They do have wireless charging for EVs in Europe and they are actually pretty efficient. Bjorn Nyland did a test on one and it was more efficient than a plug in charger.
Source?
Pretty sure there are home installs possible for the US, I think both WiTricity and plugless make modules for home wireless charging.
I saw the video a year ago. There is no way that wireless charging is more efficient. The person Bjørn interviewed is a salesperson. Wireless charging always adds more switching and transforming power.
Wireless chargers are a waste of power and copper, in my opinion.
You can't really use your phone while charging, and the waste heat degrades the battery faster
@@sharky07xy The test they did in the video showed 2 things
1. Wireless charging can be pretty efficient done properlly
2. The conductive charger they tested had horrible efficiency
Yes the sales person probably made sure to used a cheap transformer so his wireless charger looked better, but it still was impressive anyway.
Sure, for the same price a wireless charger while never be as efficient, I'm just saying that it's possible to make an efficient one and that it already exists.
4 layers of wireless chargers is crazy
I've seen only 3 layers before I reeded your comment. Now I see four ;)
"Still aint paying 7 bucks for Twitter, though." 😂
Have you considered doing voice overs for Amazon audible? You have the best voice for it. Just saying 😊
"still ain't payin 7 bucks for Twitter doe" you a real one. Salute!
it hurts everytime he scratches the products
The issue Apple had with AirPower is the small coils required for the Apple Watch. Mixing them with the larger ones required for all other QI devices is where they ran into heat issues. Apple could have definitely have made this but since they didn’t want to leave the Apple Watch unsupported (and also didn’t want to switch it to QI) they decided to cancel it.
I feel like this Tesla charger could catch fire
@@Johnnygga I highly doubt it. There are a bunch of Android phones that can charge at 65W. So 65W spread over such a large area and with tons of thermal mass should be fine… I think.
@@DoubleCTech I thought that too but I need to look into the physics of it all because physics never lies
Lack of replaceable cable is a major deal-breaker for long term use.
In many ways (including what you mention), Tesla is the new Apple...
Once you plug the charger into the wall, its probably going to sit there on a desk, bench, or nightstand untouched. So you wouldn't have to replace the cable like you would doing wired charging. Kind of like how a nightstand light doesn't need to cord replaced.
@@jamieclaudeo8107 Yeah that's kind of a fair point, it would be nice to see them put a port on the back of the thing though, it's really not much work and would cost them pennies. The cable looks quite long too, it would be nice to be able to use a shorter one if you don't need the length. It's just dumb to have fixed usb cables on things these days even if they won't see much wear.
So the 300 dollar price tag isn't a deal breaker?
@@garysgarage.2841 Compared to Apple lmao, If apple sells this sht they will price it at around 800-1k

@@SamuraiDeek The patents are all free and the repair centers are non profit. You are confusing company growth with greed.

@@TechNextLetsGo yeah, who wants to tell him that was all BS, and their patent pledge was basically untenable to anyone with a lawyer?
Hey, electronics engineers, any reason these were with circular coils rather than squares (to maximize area)? Is it problematic with the magnetic field it creates, or just harder to control?
Because then you wouldn't be able to call it a coil
/s
It’s more a question of efficiency, you want the flow of current to match the direction of the coil on the phone’s coil; squares would have little current matching up directionally, it would still charge, just much slower
The flux generated by a coil is proportional to the Area and the cost of the coil is proportional to the perimeter. The circle shape has a better perimeter per unit area compared to the square shape
There are a variety of reasons but the main ones are efficiency and ease of manufacturing.
A circular coil produces a magnetic field that is evenly/uniformly distributed in all directions, making it more efficient at transferring power to a device placed anywhere on the charging pad.
A square coil would produce a magnetic field that is stronger near the corners and weaker along the edges. This non-uniform field distribution would lead to less efficient power transfer and result in a slower charging process or require the user to carefully position the device on the pad to ensure it is charging.
not an EE, but I think it has to do with the even distribution of the field produced by a circular coil vs a square would produce uneven fields concentrated in the corners. The receivers would also be circular so squares wouldn’t match up as much.
Early gang???
As i saw you scratching the surface nearly cried 😅
Thanks for showing us!
Got curious seeing a big wireless charger in my recommendations - so I clicked on it. Not a minute yet and the first thing that happened was scratching the item.
I am reminded this is JerryRig.
MagSafe is so much better than using a pad to charge. You have to line things up, if there not oriented to the pad correctly you lose efficiency. With MagSafe you don’t have any of those problems and you can use your device while charging. It really is a perfect design.
This
If you cared even remotely about efficiency, you wouldn’t be using wireless charging
@@dennisbrannvalls1fan964 I mean charging speed
Hey Zack, I'm pretty sure the charger only pulls the amount of power needed for the device. The coils are intelligently turned on to full power only when a device is present. 😁😁😁
That power loss. Damn wireless chargers are more polluting than I thought.
people creating glass or perspex top panels should likely look into the venting of the heat. would be crazy to see it melt into the copper
Frequency matching is near 100% efficiency. Definitely possible for vehicles
Xiaomi made one wireless charging pad with the exact same 3 device support years ago for less than $50 with 20w to 3 device simultaneously, this seems like a novelty item more than anything else.
The item itself costs $75, the tesla logo costs $150+
In my opinion the efficiency loss still outweighs the convenience. Until someone finds a solution to the efficiency (which I doubt will ever happen) I will stay cables only until they remove them.
Yeah, imagine all of these coils, this must waste a lot of energy
I've had one of these type of wireless charging bases for like 2 years now. for about half the price
First thing I thought when I saw that epic array of coils, YES! Transparent surface would be /so/ awesome~
This is like the $200 Zens Liberty Glass Wireless Charger, but this has 30 coils instead of 16.
Pretty cool, Would buy one asap if it was transparent
Thanks for watching, Tim Cook 😂😂 Nice start to the video. A $300 pricetag is pretty crazy though, even with the coils embedded into it coming out to $10 each. One of major points when making something, is to ask whether the price is accessible. For most people, definitely not, considering most won't even spend more than that on their smartphones and opt for a Samsung Galaxy A-series device or other low-mid spec android. Having a charger priced equally to the actual thing you want to charge? Yeah, I don't see the success.
Even pricing it at 1/3 to 1/4 of the price of a high end smartphone makes me step back and think. It's not only here where I have that issue either, but also for example with Apple themselves, and the exorbitent prices they charge for iPad folio keyboards these days. $200-300 for a case for an ipad that costs the same amount - it's like WHY??? The iPad was supposed to be the budget option, but then you make an accessory which makes it anything but budget friendly.
I just don't see this being profitable for Tesla right now with that said. Especially given that Elon surely paid hundreds of millions on R&D for this, including creating the tooling required to actually mass-produce it. Maybe I'll be surprised though and it becomes huge.
There is no money to be made in the low-cost market for western brands. For what happens if you try to compete there, look at all the failed German consumer electronics companies. Appealing to people just wanting to buy the cheapest shit is just a race down a bottomless pit.
What makes you think you are Tesla's target audience?
Dude
Hundreds of millions on R&D for this? A separate company with the technology made it for them. It is purely meant as a novelty and collectors item. Also, most low to mid spec android phones do not have wireless charging. You are just not in the target audience.
Also, did it ever occur to you that companies need to make money on things? Even if the coils were 10 dollar each, they are free to just charge whatever price they want so that they can turn a profit. The price of an entire car isnt the sum of all the parts together ..
@@neofaktion dude.
Apple couldn’t figure it out with their trillions of dollars. Also, tooling manufacturing machines isn’t anywhere close to as cheap as you think it is. Companies commonly offset those costs by making it as accessible as possible to as many people as possible.
And you’re way off the mark by saying I’m not the target audience. It’s hardly a designer item, nor is it limited edition being made purely for the obscenely rich. If it were, it’d be priced much higher than $300.
Tesla are targeting anyone who has a wireless capable device. Maybe not with this specific iteration but at the very least as a working prototype to gauge the market
@@grahamb7947 Apple couldn't figure it out due to them wanting to combine their proprietary Apple Watch charging tech, and regular Qi wireless.
If they were targeting anyone who has a wireless capable device, then they would price it accordingly. In this case, they simply collaborated with a company who already had the tech.
That’s great to see the teardown but you didn’t compare it to any other wireless chargers, it would’ve been nice to know what it’s actually putting out other than just the “15” like does it work any better than the other wireless chargers on the market, how fast does it charge compared to other wireless chargers? is it worth a 300 price tag??
I can already imagine apple buying one of these and rebranding it for 1500$

Crazy look. Transparent you say... Very nice
That's absolutely hilarious "thanks for watching Tim Cook" 🤣😎👊🙏
yes! transparent version would be great! so cool to see.
Nice teardown! Couple of corrections... just because the power supply is capable of delivering 65 watts does not mean that it is always delivering 65 watts with just one device charging at 15 watts. Assuming 60% efficiency one device at 15 watts should require the power supply to deliver 25 watts, so the 65 watt capability is there for multiple device charging. In addition, the adhesive between the coils almost certainly does not provide critical electrical insulation. Each coil will have clear insulation coating the wires because it is necessary to insulate each turn of the coil from its neighboring turns in order to function as an AC transformer (coil on the charger is the "primary", coil insude the charged device is the "secondary"). Each inactive coil must be kept as an open circuit in order to not interfere with the inductive coupling of the active coils, so the charger must be doing some logic to identify the coil with the best coupling to the device. Otherwise, great job!
As if I'm going try a New Expensive state of the art Phone on a non smart charger. Nice tear down as usual Jerry...
Zens did that a while ago with the WLC UNIV LIBERTY 16 GLASS (even transparent) for like 200 bucks! so nothing really new, still cool to see this trend starting up....
It did not seem like 30 coils really though once you started lifting them up. I wonder if some solder connections were for thermistors or something? Neat look inside!
