I clearly noticed your mistake back then, but I said I'll just let him correct himself.🤪 On a serious note. The real sound effects are ruined by the 3 star hotel lobby music.
probably a dumb question, but I've noticed that the supplied prong plug on the 140watt charger is rated for 7 amps. Will this charger function properly with the 2.5amp Apple brand "Power Adapter Extension Cable"?
It's very nice to see active input (A/C side) recifier circuits on more chargers. That should make this a very efficient charger that stays cool when in use!
A quality charger from someone who know what they are doing, Japanese Electrolytes 😻😻, this design actually makes as it uses GaN FETs as the main switchers. Low output capacitance isn’t a major issue due to the very high switching frequency which this should operate at and this should have enough input capacitance at higher voltage because of the APFC circuit so there is more energy.
the rubber pads aren´t for isolation.The silicone is there to ensure that if the power supply falls down, no components are torn from the circuit board.
Great video! I’ve been impressed with the performance of this charger. It puts out so much power and stays absolutely cool. Nice to see the build quality along with quality components.
The teardown really shown that this brick is literally a brick.. It's built to be durable against being thrown, sudden fall, etc. That do justify the price.
Yup, that is a well made power supply, no doubt. It is durable, I know as my last Mac PSU frayed at the PSU so I "opened" it up. LOL that was a laugh, I just spun it around on a piece of wire and then let it collide with a wall, split open and then resolder the wire on, tape it back together, just like a bought one 😂
Well its Apple so it isn't cheap, but that is a nicely designed and built PS. I really love that Apple has, at least for this series of laptops, forsaken the thinner is better paradigm they've lived by for so long. Yeah, slim and light is nice when you're carrying it around, but to have the power you want and the cooling you need the new M1 Pro and M1 Max MacBooks are a refreshing reprieve from the thin above all else mindset that Apple is known for. Painful to see that nice PS torn to pieces.
ha the Reality Distortion Field is as strong as ever. Now it turns out that "thick is ok, heavy is ok, notch is ok". Just imagine for a second Dell or HP released a machine with a notch. You fanbois would have laughed your ass off. Oh but it's apple doing it? Carry on. "it's a machine for professionals who need high performance". Get real. Get a desktop computer.
@@83hjf -- I don't have any Apple products except a couple retired iTouch icons, not an Apple fan boy. For too long Apple has lived by the idea that thinner is always better, but for these new MacBook Apple went the other way to provide more performance, better battery life, and better cooling so the fan isn't always screaming -- yeah, I think that's a better strategy.
General question - how reliable is the USB-C connector when passing 5 amps? I guess it's only 1.25 Amps per pin (there are 4 ground and 4 Vbus pins in the USB-C connection) but it still feels like a lot for such a small contact area.
The USB-C PD spec states 40 mOhm max contact resistance per power bus (i.e. VBUS is max 40 mOhm, GND is max 40 mOhm, etc). We can see at 2:40 that the Power-Z PD monitor is reading 27.75V, so assuming a perfect 28V regulated output this is 0.25V drop at 5A, or 50mOhm total, 25mOhm per power bus, dropping 1.25W at each connector. This is of course a rough estimate as we don't know the unloaded voltage or how close to spec the Power-Z PD monitor module is, but it seems well within spec.
@@peter.s.3207 Interesting. I looked this up - I read 40mOhm per contact in an Amphenol spec. Since there are four contacts in parallel then it's nominally only 10mOhm in each rail so 20mOhm in total. 5 Amps through 20mOhm will only dissipate 0.5W in the connector which isn't great in terms of contact heating, but I am sure the designers knew what they were doing. I won't be so worried about this issue in the future. Thanks.
@@GodmanchesterGoblin Oh that's kind of odd... I doubled checked the 40mOhm figure and it seems like different sources are saying different things (per bus vs per contact). I rounded up a short USB C-to-C cable with a power meter on both ends and got 25mV drop at 660mA, which is pretty close to 20mOhm per connector (plus the wire) so looks like that's indeed the correct value.
I presume the synchronous rectification helps achieve very high conversion efficiency, so that a 140W power adapter can be fitted into such a small package without cooking itself at the first opportunity.
The GaN switchers help most in that regard. The synchronous rectification helps with the power factor correction that everyone is hot on these days (apparent vs. real power) as we're most likely going to get a bill for difference 😋
All the parts used seem to be really high quality to an amatour. What's your opinion, were there any cost saving measures used where using even more expensive component would have increased total efficiency of this charger or improve it expected life-time? Or is this truly no-compromises build for this kind of charger? (I think they could have made the charger not-glued case but that's obviously an intentional Apple design decision to avoid screws, not about making it cheaper to manufacture.)
What I've never understood with Apple's chargers is the way they can't seem to decide if they are making a class 1 (earthed) or class 2 (double insulated) product. They have that earthing "button", but it only gets connected if you use the apple-supplied mains lead, if you use the plug heads it just gets left floating.
It's necessary to make a charger that works with a floating ground anyway, because some major markets (mostly Japan) basically don't provide earth on their sockets anywhere. Passing the ground through to the device through the cable is an added benefit where you're able to use it, but it's not a guarantee. And I'm guessing it would be harder to provide that folding design with the extra earth prong anyway.
@@carholic-sz3qv i have never seen one . I think dell has one usb c charger that has gan fets but definitely most high end ones still use traditional mosfets. My friend had his g15 power brick die.& So i took it apart and replaced the output active diode which was shorted and did not see any gan fet on the input side And it's a 230w psu that gets bloody hot while gaming.

Feels a bit overkill in few areas, but it is definitively top notch quality design, components sourcing and safety. The flux residue and very hard access to inside (i.e. to repair something like fuse or the broken output port), is a bit meh. I do not own any Apple computers, but I guess it should work with other laptops?
Was looking for a new USB charger but could not find the output ratings for these. Glad that i found your channel, thanks to your comparision sheet i can now select a proper charger for my needs. Thank you!
@@古明地恋-s9c also I just realised pd 3.1 spec goes up to 240 watt. Also there are new GaN batteries that can charge at a linear speed begging to end, rather than slowing down when almost empty or full. Imagine a 100Wh GaN Battery with 240PD charging. In theory it would be able to charge in only 25 minutes from 0 to 100. That’s something far into the future, but we can dream
Ummm, no the reason why the charger is slow is down to the chemistry of the cells it is trying to charge. As the cells become more charged they become more inefficient and will take more power but charge less as a proportion. You can charge them hard, but they'll get hot and you'll waste a ton of power and dramatically shorten the life of the cells. GaN will just make the charger smaller, it might accelerate charging a bit, but it won't allow you to fully charge a lithium chemistry cell to 100% quickly.
I'm hoping for more laptops to support USB PD 3.1, I've had my eye on a laptop for a while but it doesn't support USB C charging, it uses a different connector. There are adapters for it of course, but I'd rather not be required to use those if I can just have a single cable.

What amazing about apple device are the inside with black PCB. It just sad most people can't see it, because they don't allow you to repair your device or open it. They made it so hard to open their device.
Nicely made power supply, it is a shame the "duck head" adapter that it plugs into doesn't bother to connect the ground pin, thus leaving the MacBook Pro case sitting at half of line voltage, not a problem for people in the US and Canada, but for those who have "real" electricity, like mine is 245V - the case runs at a rather tingly 120V, it is the 4D experience that everyone's been talking about 🤣 I guess it saved Apple a few cents on a $6k laptop...
The extension cable does connect to ground pin. The folding connectors do not because a folding grounding plug would be enormously bulky and no longer fold 'in line' with the charger shape.
Does apple 140W USB-C power adapter deliver any input voltage between 100 and 240v at a frequency between 50 and 60 hz? so it can be used internationally?

Fuse is designed to protect user e.g. from fire in case of fault and not to be replaceable.
@@rhiantaylor3446fuse is not replaceable? In the world of Apple?
Yes.
More disposable apple crap for the landfill.
I've opened older MagSafe chargers without a Dremel, did they change something?
yes they changed it smh
From your assessment could this charger be made smaller with current technology?
It can, but the heating will be a big problem. We need to balance the user experience and size.
@@ChargerLAB , thanks for the reply
you can open this easily with heat gun or some thing you heat with this , thanks for video .
What's the point of an inaccessible fuse?
Wow! now this is a teardown video!
Great insight! Thank you!
Hi, would this be able to charge a Lenovo laptop? I have a Lenovo P1 Gen 2
If your laptop supports PD fast charging protocols, then Yes.
or NO.
For me it's an Awesome and interesting video ... could u please explain working of each component in coordination to each other ? And why it uses microcontroller which has mem unit ?
5:04 he has an electric screwdriver and does he unscrew the screws by hand?
We have no money to buy batteries😂, just kidding～
This is simply incredible. Love your video too.
Thank you so much!
Incredible video quality and explanation!!
Must be a typo in the 67w charger output - if it would support 15v 5a - it would be at least 75w
Yes, it should be 15V 3A, sorry about the mistake.
Camera is so blurr, its irritating while watching with focus on such a great video
Very well designed 👍
It has to support PD 3.1 for 28V.
Love this detailed teardown
... there's a CPU in a charger. We've come a long way.
Can I use my iPhone 7 140w power adapter
Yes, you can. But I'll charge at low speed.
This charger is a monster on the MacBook M1 PRO/MAX 16
