120W at the output from 100V@0.5A at the input? That's not a power supply, that's a FREE ENERGY DEVICE!
Well, that's a good point :)
200% efficient!
Chinese overunity 😂
Happy lunar new year 🎉 🍯🍯
Plot twist: It uses the refrigeration cycle to charge your phone
50 w💀
The fact that they skimped on the 0.5 gram in the 10grams weighted plate is amazing.
Chinese scams even itself.
Thats including the 0.5g of tape still attached to it
that just killed me 😆🤣
Why be honest in an dishonest product?
P.M.P.O. grams :D
The power supply gets so hot that the sticky tape could fall off and the steel weight could short something out
That's the thermal overload safety cutout!
ya he said that before in one of his videos
Have you never heard of a crowbar circuit?
@@Electronichub_05 ?
It's a 'drop-off' weight.
I love the 10 gram weight weighing 9,5 grams. Is nothing holy any more???
Beware, the 9.5g was measured on a cheap Chinese scale, so the uncertainties add up. It can be anything from 9 to 10g...
The extra 0.5g was the adhesive that was left behind... Maybe? 😂
China has a different gravity)
We should just rename the Chinese the Shavers at this point. They just have to shave a little every chance they get. Every 20 weights it is like the manufacturer gets one for free! That sort of thing can really add up for them.
It's 10 grams +/- 5% so the weight is 9.500001g /s
EVERYONE should use this video to raise a dispute and get their money back. It's not about 3$ it's about seller not getting paid! There is no other way to stop them blatantly lying like that!
Dude it comes from china, nothing will ever even reach the scammers
I've done that, and you'd be surprised at the outcome.
My claim was accepted, but the seller said *they* have been screwed by the supplier.
It looks like the sellers know next to nothing about the stuff they sell - they only know how to sell - so the producers lie to them.
That's not an excuse to feel bad for the sellers, they should get a different job - but that just shows how dishonest the Chinese are to *everyone*.
There's way too many that do this, you'd be playing wack-a-mole forever.
They refunded me on a similar charger, and also on an USB cable that was lying on specs
@@LMB222 Pretty much what I was going to say. OK, the seller is responsible but they are just box shifters, if you get one removed from the platform there are 5 others waiting to take their place. What is needed is the platform (Aliexpress, Temu, etc) being held accountable by the customs for the lack of proper safety provisions, it does, after all carry the RoHS mark but clearly does not comply.
I love the 1.5 mm² wire as the pointer 😂
After seeing the fake weight, the cat concluded the sentence. 2:38
We need more of the cat's opinion, I'm here for the cat.
Let's get one thing clear: 120w is not total deliverable power, but name of company producing this charger.
Well, it's easier than printing WWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWW 😅
@@GodmanchesterGoblinHAHAHAHAHAHAAH
A remarkable and masterful forensic analysis: one of the best examples of technical communication I have EVER seen!
Carry on good sir!
Next time, maybe you could also try whether the resistor is actually fusible?
how is that possible to comment before the video was published
He has a time machine 😊
the video was published 1 hour ago, how did you comment this 1 day ago
@@ZA-gv9bz video was uploaded 2 days ago for members only and this guy's probably a member of this channel.
@@Pratik-india47 wow, the more you learn, didn't think that would do that
“Let’s cut the corner. It definitely contains a lot of cut corners inside of it anyway!” Excellent summary!
Becareful of these cheap Ali Express things. I got one and it started making smoke. If I didn't turn off the power, it would have ignited into flames. My bed sheets were very close to the power point so it could easily have caused major problem.
6:03 i love how you announced the melted hair dryer as if it was standardized equipment for dismantling a transformer.
thank you for explaining everything super fast. other youtube videos will take to do all this like 3 moths duration. keep it up bro 😍
Respect for the solid-core pointer at 2:50 o7
it's straight forward - "120W" is a brand name :-)
My doppelganger has spoken ...
The connectors are probably the most expensive parts. I've also had cheap chargers where the connectors were not even up to spec, could not even handle 600ma.
looks well made from the outside, I could've fall for it, at least I expected the USB-C ports to have at least 15w of fast charging, so sellers on stores may plug it into customers phone and it would show "fast charging" at least so they can sell it and get away. Curious to see that even dodgy chargers are using synchronous rectifiers now.
Synchronous rectifier chips became very common. Once mass produced, they're very cheap. When something has been around for years, the main production cost is the materials. A diode contains more of them to handle more heat loss.
This is not for over the counter sales, so the tire weight does the trick.
120W refers to the number of times you say "what?!?" while analysing the circuit and reading the ratings
Making a post to sate the hunger of the algorithm deity.
You have a really nice cat. *Thank you* for sharing. 👍👍
bro has more disclaimers at the start of the video than harmful products have on the labels 😭
The 10g are equal to 9.5g because these are Chinese grams. They include the bag for shipping
Like 100g solder from aliexpress is 100g WITH the spool
Cost of components 5$, cover 4$, shipping 30$, tax and duty 3$, customs fee 5$, but they do all of it just for $3.
Shouldn't this SMPS be ultra dodgy? Being super fake specs, unsafe circuit board etc?
Yessss! I remember, similar quality chargers was rated SUPER DODGY! I am disappointed, where is the consistency? 🤣🤣🤣
Super dodgy means without fuse and transformer without tape I guess.
Bruh, a 10g weight weighing only 9.5g, WITH residual glue on it, REALLY? they really couldn't afford that extra 0.5g?
Maybe it's a 110W heater with built in 10W charger!
2:40 "chinese 10 grams are 9.5 grams" this is deep truth !! very deep
Ah yes 12.0W charger
But the dot ist yellow, thus invisible 😅
I love me a charger measured in "Cheap Speaker PMPO Watts".
The Fe on the weight indicates 'fake electronics' presumably.
CFe for Chinese Iron
Thanks again for the wonderful work you're doing...
i like to leave reviews for these mentioning that the weight can come loose and start a fire, the rest is implied
I had one of those pieces of crap and the metal became loose inside and it caused the charger to explode
omg, I recently got this charger, and checked your channel for a video, I saw a similar one, but now this is the exact one.
I got it for $2 to have extra slow charger because I also got proper fast charger and don't always need fast charge. It makes high pitch noises
"10 Chinese grams" I laughed so hard! xD
Wow. Glad I discovered your channel. Never knew europlug pins are supposed to be angled, you learn something new every day. That protocol reader seems very useful, any advice on where to get one? Are the ones on aliexpress any good?
Anyway love the content, keep it up.
120W here is just a brand name. Like "2TB" hard disks in Aliexpress and Temu.
Or 6000mAh SuperFire 18650 🤣
Hello, and thank you for showing us this dodgy charger, I saw the same one (as shown in the video) for sale on Aliexpress Korea (I sent a picture of that charger on email). Seeing one for sale with that low of a price is just unbelievable, and 10000 people buying this kind of charger without assessing the risks with this is quite worrying. Thanks for the video. - Alex
I love your vids. Please keep them coming
Thanks mate! I hope you have a playlist of legit items. 🙏🏻
Thanks for the analysis. Those gadgets are in fact quite DANGEROUS!
For 3 EUR price tag definitely. You can't get quality for such absurd price.
It is not a USB charger; it is an IQ tester.
Ha! I ordered this charger's cousin (has a LED display for V/A) that is advertised at 20W a few weeks ago. My load testing showed it reliably died >9.5W, and got warm doing it. Took it apart like you did, and found the Chinese switching supply chip, which in the datasheet clearly indicated it was a 10W max chip. The reference circuit in the datasheet was basically the charger's circuit, but with those janky clips to allow different country plugs to be swapped on. Right into the trash - waste of $3.
Lol, i have this exact same POC from Aliexpress, thankfully i got my money back after my usb tester showed it incapable of matching any of it's claimed stats. Had kept it around in case it was usable for anything, but after watching this video IT'S GOING STRAIGHT IN THE (recycling) BIN!
When I clicked the video I was expectimg super dodgy charger 🤣😂.
Anyway coool video😁👍, thank you 🙃
That's a very chill trans. for 120W job :D
great breakdown, you know your stuff!
Do you ever go back to them for a refund after you have proven their claims are fraudulent?
Thanks for reviewing this, I was thinking of buying one earlier.
When they printed 120W, they probably meant when there is a shortage, and there probably will over time, it will convert 120W into heat and melt into a puddle.
I was subscribed but for some reason yt showed i wasn't! Love your videos and your cat and have subed again. Cheers.
2:56 in cheap enough electronics, any resistor will be fusible 😂
but hey 5x3.4 is indeed 120, professional mathematician here
4:08 - in case anybody is wondering about USB-C, there is a 10K pull-up on CC, which corresponds to USB-PD source of 5V 3A (they could have gone with 22K for 1.5A), and the A6/A7/B6/B7 (D+ and D-) pins are shorted and pulled up with 43K and down with 51K, which is BC1.2 for an Apple charger of 5V 1A. Dodgy indeed.
$3...
It would be nice to check cheap ones from aldi or lidl. They don't pretend to deliver 120W but I bought some at ~$5 recently and they look ok and not that hot at max power. But I didn't opened them...
The bigger, well known stores have much more to lose if they are found to be selling unsafe products, so the quality is usually a lot better. That is no 100% guarantee, of course, and there are still sometimes product recalls.
I consider them to be trustworthy. I have a couple of their chargers. It is better to buy something like this, than a phone manufacturer one that are often fake.
I collect dosimeters sometimes old, if one breaks could i in theory send a broken one to you and you could fix it?
I realy like ur usb c cable
Where did u buy it?
Por fin el video en español😀. Saludos desde españa.
¿hay algun cargador de xiaomi origuinal de venta en aliexpress que sea barato y origuinal ?
It might be for the best that it's 5V only. It's still a fire hazard, but it's less of a fire hazard than if it had 120W running through it, with even more corners cut to achieve that.
Using those wheel balancing weights is kind of cool.
They are to balance the power factor😂😂
that and sand is a classic chinese scammer trick
"don't open mains equipment unless you're qualified to." That's the trick though, you don't know you're qualified unless you survive!
Me as soon as I see the title and thumbnail: That's a dodgeyy charger!
What is your best choice of cheap charger PD type from Ali that tests ok?
probably something like ugreen, essager, baseus and rocoren
None of them probably... Just get one from a reputable source
Dont, Ikea chargers are good, they are like 10 bucks.
Buy a charger locally that has a genuine safety certification and EMC/RFI compliance. Buy from a normal retail store.
Ugreen. Often what you'd buy in a store locally is just rebranded ugreen.
Great teardown.👍
Conclusion
This charger
Support 40 w
Every port support 10 w x 4 = 40w total or less
I think that's the exact same pcp I have on my bench for repair right now. I think mine said 65W, but it also is 5v 2a max.
Even an additional weight has a pinch of fake 😂
Laughing a lot thx 😂😂😂
Probably delivering 120W when it is blowing you up when using it for a longer time... delivering full voltage to the USBdevices for a short time... really not that well made.
For such constructions I suggest using the term "DODGY AF!"
I hope you dont get heavy metals poisoning from touching the electronics.
Can you provide suggestions on chargers that are actually real and great quality that you have tested or know about? Now its hard to not get fooled or scammed on amazon and stores in general.
I love how the scammers got scammed by a 9.5g weight 😂
To be fair, 10W 4 Ports could be useable for many trickle charging needs
Please test Essager 100w charger to see if they are the same but in different enclosures.
Heading towards poles of earth reduces gravity.
I bought 4$ aliexpress GAN charter and tested it myself. Can handle about 33W via USB-C. Even has x1/y1 cap.
No water splashing, still 10/10
Hi im from thailand i order it from lazada and it doesn't even do a fast charge also it charge the phone very slowly and it get very hot so i decide to tear it apart it was very garbage never trust cheap stuff
I also recognized the usb c cable plugs 😂
So, not even 120 deciwatts. But seems to be great a socket heater and surprise fire starter. I wonder if the "added quality" actually is mostly iron, or if that's how they get rid of spent nuclear fuel that they can't use to make weapons.
Ďakujem ti za video z tejto peknej a hlavne užitočnej série o čínskych nabíjačkách. Aj som si hneď myslel, že tie USB konektory (ich napájacia časť) budú zapojené paralelne.
Eta nabijacka nie je dobra!
@@MortimerKadaver Ale nie napisałem, że ładowarka jest dobra, tylko pochwaliłem ten filmik (Google Translator used)
@ To viem.
Len som žartoval. 😉
problem je v tom že jiná než Čínská není! 99% nabíječek telefonů se vyrábějí v Číně :) neznám nabiječku telefonů- made in USA/Britiš :D
@@220volt-u7 Baseus is from China. Xiaomi and other good companies.
$3 is nothing. So, you cannot expect good quality.
It is a shame they glue everything together now, so you can't check something non-destructively before using.
Some of the ones 3 times the price might be OK, or they could be just the same junk inside.
I've seen some transparent cased USB chargers on aliexpress, but either the dodgy small transformer can be seen or the photos are computer generated.
what they mean with 120w max is that when it electrocutes you it will draw at most 120w of power. Cheers.
I have one of those and use it daily.. lol. however I never thought the 120W was remotely real for the price. I was hoping for 18w or something really. kinda expected the dissapointment.
It is hoever used by one of my children..if I never plug something demanding more than < 20w is it safe? otherwise I'll throw it away.
No, there is very little insulation to prevent electric shock. I would throw it away.
@@dino6627 I have problems with the accent of the dude of the video and can barely understand it,.. I guess the galvanic isolation is poor or non-existent so one might get full mains power out in case of failure...right?
@@crrodriguez Insulation is only thickness of enamel on winding, which can easily break down and give mains voltage on USB output.
Could you imagine that thing actually delivering 120W? At 80 percent efficient that would be like 24W power dissipation... Imagine shoving a 24W heater inside that case... In order to be feasible it would have to be more than 90 percent efficient. That's active rectification bridge and secondary, active power factor correction, really expensive switching components.
Does anyone even make something like that, in that form factor?
Phones have a data line that they send out their capacitance and it goes down as the battery heats up.
So the charger is supposed to regulate the amount of voltage they are sending the phone to keep the battery from overheating
There should be a chip on this one to regulate the voltage and the chip should have a pin to connect to the data line from the phone
I think it got off lightly with the Dodgy rating. Given all the shortcomings I had it down as Super Dodgy.
At least 3 safety critical parts not safe? That has got to be SUPER DODGY.
i had similar story, ordered two 67W chargers and had same content inside... charger gave 1.5A max while voltage dropped to 4V.... i clicked refund at aliexpress, attached some photos and description and money was returned within minutes... you can keep the adapters and you get your money back.. no one required to send them back.. at lease i got 2 free usb cable, which are not bad quality and two chargers for charging led lamps or small devices maybe..
That´s not even dodgy, that´s more or less deadly.
😂
I am sure that the thing that it says on the charger are fake but if it has usb c pd (what 99% of usb c chargers use) that you need a trigger board that talks to the charger to get higher voltages or more amps. if there is no trigger board they often only give like 5V with 0.5 to 2A
The chrager was fake but your voltage/apmere testing would not even have worked if it was not fake (since no trigger board)
To nevíte, že číňani mají jiné jednotky? Musíte jejich výkon podělit stem a potom dlouhodobý výkon odpovídá! 🙂 To platí u všech jejich výrobků. Baterie, generátory, audiozesilovače.
Don't you know that the Chinese have other units? You have to divide their performance by a hundred and then the long-term performance corresponds! 🙂 This applies to all their products. Batteries, generators, audio amplifiers 🙂
Just an electrocution interference generator? Drat, I needed an electrocuting house burner, but that is kinda hard at just 5V 2A.
But at least this one has two ways to electrocute the user, yay for redundancy.
Love the videos
What a dangerous piece of junk. Ali express will gladly sell a death sentence, at a discounted price. I remember back in the day where all electrical devices in the USA had to be UL rated for safety. Cheap imports have overrun the landscape here. I even have seen some lamps for traditional light bulbs sold with non-polarized plugs. It's a free for all, and the only way to be safe is to be knowledgeable. Thank you for making these videos.
your sense of smell came back?
Smells like burnt electronics
-Another charger
-Video is less than 10 minute
oh yeah, of course.
Holy chip smoke! not even able to supply a 10th of rated stated pwr! Gotta be a new low! 🤣
I personally use the phone charger that came with the phone. I actually bought a second one for 20 dollars.
The real phone charger is a smart charger and it is expensive
