Can 3 USD really buy you a 65W GaN USB charger? Let's test it and see what's inside. Please support my channel on Patreon: / diodegonewild Instagram: / savage_danyk
They look to be tire balance weights of some sort, and not very good ones. It’s China so if your Xiaomi’s wheel flies off after it develops a shimmy it’s not a big deal.
The weights are circuit breakers and a safety measure. When it gets too hot inside the enclosure, the glue melts, the weights drop down and short-out the entire thing. Then the mains breaker will pop if there is one. Very clever safety system!
If they were honest and sold them as 5V 2A without the weights, they would actually not be that bad. The isolation distance and transformer are much better than a lot of other cheap chargers around the same price, and it can actually output 2A continuously.
Same products are available on real ebay/amazon just price is somewhat higher, at least on AE is easy to pass things like this. Nobody with at least part of brain working will believe that for $3 you can get working 65W charger.
I like this very much - it only supplies the voltage that is not written in the specifications and none of the ones specified. And it contains random automotive weights that don't even match the weight written on them. This engineer is a total anarchist.
@@schaltnetzteil495 - At 2 Ampere and possibly 450mV drop voltage the diode would have a power drop of ~0.9 Watt. A PRLL5817 (for 1A average current) would have 150k/W thermal resistance from junction to ambient, so I would use two of them. With 75W/K it would get ~95°C at the junction. Possibly it is worth to check this synchronous rectifier.
@@schaltnetzteil495 The cheap ones are just a diode in a different package, after all the lead wire from the big ones contains a lot of copper, much cheaper to have a die mounted on a thin leadframe, and then the other half is pressure welded on top to make contact, followed by the thin layer of epoxy. Amount of copper is that in 1cm of the lead of the big diode, a considerable saving over a million units, plus you can recycle the rest of the leadframe as well, not send to the buyers for them to cut off. Can even use tinned steel as well, as there is no bending involved in assembly after epoxy forming.
Older ones were lead before it was banned by bureaucrats. If not, everyone would have died from lead poisoning and the world would have ended years ago.
5:43 the drop of solder that stick to capacitor is to balancing the charger in conjunction with the weights. Explanation: when you trow the charger to the trash bin it as to be stabilized to center the trash bin.
It's amazing how cheap they can make these GaNs nowadays ;). They're even wireless and glued to the plastic housing. Nice to see the "new" transformer disassembly gun.
Ok just as I thought. Faker than fake ... All thoso people using these dodgy things. I do wonder if some of the slightly more expensive ones do actually supply 65W vid USB-C PD?
I recently bought 2 brand new Motorola Edge 30 neo phones for my grandparents and both came with 68W USB C chargers. I don't think Motorola (Lenovo) would lie about a power rating :) Though i would have to check the real output.
@@LMB222 Chinese people are humans, just like you and me. Lenovo is a big company with a name and reputation to protect, which means that just like HP or Dell they wouldn't sanction or ship this kind of crap. But they might cut corners or make bad design choices to deliver on aesthetics or price, just like Dell or HP might...
@@Clyde-3195 Is the Motorola brand really owned by Lenovo too? That would suck ass... Wouldn't put it past a lot of companies these days to be out-sourcing the design and manufacture of products while slapping their name on it...
One other test you could have performed was a primary to secondary flash test - see whether the insulation between windings could withstand 500 V or 1000 V without sparking-over... I bought some of these devices to use as low power 5 V supplies, (get 9 volts if I can), but the insulation must be tested... Loved your video ! 😊❤😊
My professor who is an electrical engineer works with a chinese company, and they developed the 65W GaN chargher which is exactly the same as the yellow in the video. He handed the prototype (It's not even available for sale) to me and it weighs around 190 grams. And, most importantly, it works very well. I can't believe I found the clone of the charger they are still designing! I wonder how is it possible that they copied the shell even if it's not for sale yet
Excellent, good work from a professional. You have revealed the other side of the charger. More videos of other imitation chargers, such as fake Samsung chargers with PD graphics, and I think you have mastered the reverse technique in this work 😂, thank you.
Would bet that "syncronous rectifier" is actually a regular Schottky diode in a 8 pin package. One pin not connected, because a diode is a lot cheaper than an IC to make.
@@DiodeGoneWild with the large copper pads and good thermal connection via the pins it might make it, though you can be sure some manufacturer has made a diode in this package as a way to make money, replacing the low drop ones with fakes.
@@SeanBZA No. Sync rectifiers are expensive because of the analog circuit design. If you clone one and just pay for the silicon cost, it can be cheaper than a diode. I used to contract design a PV panel antiparallel solution, and it turns out using SGT FETs and a clone SR controller being cheaper than using a proper SBD and its thermal solution.
@@bskull3232 If you are a fab diodes are the cheapest product, no masks needed, one diffusion pass, no etching and then aluminium on both sides and copper over. Then scribe and break to make the diodes. Not like the dozen or so different diffusion steps and masks needed for a mosfet. Diodes are basically like a solar panel, does not need great quality silicon, and defects are weeded out in test and recycled.
@@SeanBZA Lithography for power devices is dirt cheap. They use Hg lamps, so the maintenance is incredibly cheap. When you talk about things made in China, there are either technology mastered by the Chinese and dumped at zero profit, or imported stuff that nobody uses. Hg lamp steppers fit the first category. For some $150k you can have a mass production grade Chinese Hg lamp stepper. That alone makes lithography virtually free for power devices made in China. Litho is so cheap that most Chinese SBD devices, even low voltage ones, use a trench gate design (TMBS). And yes, those "diodes" are secretly a self-biased near-native MOS connected in parallel with an SBD. Typically an 8" Chinese trench SBD wafer costs some $170 CNY, an 8" Chinese SGT MOSFET wafer costs $280. But for the same amount of current, the SGT is way, way smaller.
That was a great video, I just got a few of these charges and noticed they were just 5v but it's fine for the applications I needed, thanks for opening it
I don't know if you have Action stores in the Czech Republic but they have many electronics at very low, sometimes suspicious prices. It could be interesting taking a look at some of them :) They also have GaN chargers.
Yes i actually have them in the country I also have some more chargers with pd non gan and they seem better built. I did an autopsy and they have good isolation, proper Y cap, sufficient isolation in the transformer and a fusible resistor. Idk about the gan one though, still have to buy it. I get my monthly money in a few days
@@309electronics5is there a follow up on this? Here in Austria we have Action too. Also we have the Shop Tedi here and they also sell cheap china stuff like Action and some products are the same. Chinese stuff from these Shops are just trash. I bought a brazz brush but it turned out to be steel and only coated in brazz. Also bought there a frame for a picture and the measurement are not accurate. What I want to say is, based on my experiences, I would not be surprised if many products are a scam. However, when it comes to electronics I think there is a standard for these products, even if it's low. At least I hope so in my wishful thinking
Generally i wouldn't buy or use cheap aliexpress charging bricks, no matter what they claim what they can do, i rather spend a few bucks more on a brand i trust and then get something that wont kill me
I have 120W version of this. Which is basically the same PCB and the same iron weights but doesn't have Type-C ports and advertises QC 5.0 120W over USB Type-A lol. It list 5V with 9A, 9V with 5A and 12V with 3.6A outputs. And these doesn't even match the advertised 120W. I don't know what they smoked. Model Number is TRG-159.
Hmm. Those outputs would be maxed at somethinh like 45W/45W/42W... So if you apply sketchy and very bad math, 45W + 45W + 42W = 132 W ?! Even if that actually worked /somehow/, I think that with 3 separate devices plugged in you might burn down your house.
Why do you think the core has an airgap? (At 8:20, for a transformer this seems to have no real purpose... Maybe for very fast load changes the inductance should be limited to allow changes in the DC component?)
it's important because it's a flyback power supply, where the transformer works more like an inductor with more windings. It prevents the core from saturation (but yes, it also reduces the inductance). There's a lot of DC component (the current only flows one was in the windings).
@@DiodeGoneWild OK, I see! It's not just there to scale the voltage like with a half-bridge circuit. (How silly of me... too distracted by the cool disassembly footage, I guess.)
My rule of thumb: Only buy chargers that are sold by the manufacturer of the product. Even if it is much more expensive. There is a reason for that beyond profit. Cheap out on electricity and circuitry at your own peril.
You can actually get safe & real 35w and 45w chargers from Asometech & Essager that are actually well built, the 35w one is around 6-7$ and the 45 is 10-12$ and they are actually probably built & safe chargers for that price based on the teardown I've seen, quite a good value just not this!
I think the mass they used is for automotive purposes and they weight a bit less because the tape that holds them was in the case, so i think that the weights have the right mass if they have the tape on them.
the 2 slugs you pulled out may be loading ballasts for the transformer. if you have any more of them cheap chargers you may want to try testing them with and without the metal slugs and see if the waveforms change. it may be possible that there are some varying quality of the transformers maybe even pulls from junk boards. we see on other videos where people in china heat the boards over a fire and pull the parts and assumably to reuse them
I love your videos. They are very informative and show the true side of the cheap china electronics. If possible can you review the liitokala battery charger. They have very good reviews on ali express and are also of reasonable rate.
Seriously, this channel could be about anything, the study of a vegan poop/ fart Vs paint stripper on a Tesla, I mean anything.. BUT… I watch the channel because of that beautiful cat. 😻
I love the Chinese products. If they don't work as advertised I simply report it on the store and immediately get my money back. If everyone did that the sellers would be punished enough to stop lying about their products. I have bought high power usb supplies and they worked fine.
I was initially thrilled to buy this as Ali Express claimed it to be a 65W charger. On receipt, I found it to be a slow charger, cheap built and I told Ali Express. They are in the process of refunding me the amount I paid. At £1.67p, don't expect it to be of the original quality!
OMG A comedy charger. Solid state indeed, with wheel weights that need their own weights added, trouble is they would never reach their stated weight given this "standard". Zeno's bridge problem.
The conclusion is: dodgy, super dodgy or what? I can't figure it out by myself. Some part of me tell it's just dodgy from an general electrical safety perspective, but as the overall product, it's very dodgy. It's likely in between. We need to refine the categories.
If it weren't for those weights double sided taped over the board I might go with just dodgy. Those weights hanging there propels this device into the range of super dodgy though. Because there's no way that tape is going to hold forever. Those weights will fall off and short that whole device out.
The funniest thing is, that it actually does not mention the only thing it is really able to provide which is normal USB-Standarf of 5 V with 2 A of current , which is not even that bad if you wanted this.
So just to be sure, it's better not to buy chargers from Temu, AliExpress, and similar marketplaces? And instead, buy something certified from local sellers? I bought a 3m charging USB-A to USB-C cable on Temu, which was supposed to be data-capable, but unfortunately, when connecting to a computer, it keeps disconnecting. When charging, my USB tester shows that only about 0.6A flows through the cable, while with a cable that's about 1 meter long and three times more expensive from a local seller, the current is around 1.2A.
@@TzOk Honestly lead weights don't seem like that big a deal to me, other than the element of deception. As long as the lead is encapsulated/otherwise protected to reduce the risk of it leaching, it's hardly a crisis. Using them only in products with a long usable lifespan and recycling as necessary would be just fine. If it weren't for the sheer laziness of humans (and purely profit-minded corporations) we wouldn't have half the environmental contamination that we do...
They're likely to be manufacturing rejects with casting error that couldn't be sold for the purpose, but it was cheaper to sell them as defective than to re-cast them.
I keep waiting for the day where Clive or DGW are going to take apart a piece of premium chinese engineering and see a note to themselves etched into the PCB
i had an €1 counterfeit apple charger 5V 1A , it blew under 10 charges , and i charged an ipod nano , to give you a picture of the chargers performance ....
IKEA's triple type A 5V output dumb charger that BigClive reviewed several months ago (or a year) is safe enough, capable of long term 15W, and costs the same as this tested one - I bought one myself and think to by more, because well built simple chargers are dissappearing fast leaving only products of questionable quality in the cashiers area in the supermarkets while grate many things in everyday life don't need more power.
Thank you for making this video! Good quality video. Terrible bad Chinese product. Maybe check if the pieces of metal are radioactive, or if they contain anti matter.
Even the internal weights are lying, that's hilarious
"Chinese 10 grams" 😆

The weights are circuit breakers and a safety measure.
When it gets too hot inside the enclosure, the glue melts, the weights drop down and short-out the entire thing. Then the mains breaker will pop if there is one.
Very clever safety system!
🤣😂🤣🤣🤣
Very clever application of a crowbar circuit
Sounds like a "crowbar circuit" to me! 🤪
lol nice joke
This is probably what they secretly mean with the lacking "automatic overload protection"
Best part is wheel balancing weights. Apparently they help balance an electrical load as well as rotational.
It's purpose is for wireless charging :D
Picture this, somebody proudly presents a mod where he balances out their force feedback wheel in a game controller that way. xp
It aids in steady flight, from the users hands to the bin
I laughed a lot at this part 😂😂
They will, likely, claim "65W" is the model number, not the electrical rating. This seems to be the new ploy.
how do they get around advertising 20V@3.25A then?
That's 20 Velociraptors Carrying 3.25 AA batteries. It was a typo they forgot the other A.
They do not need to do so, because they will go unpunished anyway.
Like that "600DB" horn that doesn't destroy the universe when you operate it?
@@n-steam That's just the serial number. ;)
That is destined to briefly become a 2000 watt charger in spectacular fashion.
Na, 240VAC by 10A is 2.4KW
Problem is, 2kW won't trigger your house's circuit breaker.
Maybe even 5-10kW.
Even a gram is not a gram in chinesium devices 😂
it is almost a gram!
First, we had Chinese watts, then we get Chinese grams, what's next?
@@und4287 Chinese CC for engines, unsurprisingly enough.
It is a relativistic material, ignorant westerner!
Hmm and I am always wondering why after changing tyres they are again out of balance... I suppose chinese grams explains why 😢
If they were honest and sold them as 5V 2A without the weights, they would actually not be that bad. The isolation distance and transformer are much better than a lot of other cheap chargers around the same price, and it can actually output 2A continuously.
But no proper safety caps, so cRap.
5V 2A at that size? nobody would want that.
You can buy a 5V 2A charger barely bigger than a socket plug.
Yeah, but with the switcher chip at 90.7C with the lid off, it's life at 2A will probably not be the long.
@@paulstubbs7678Or the transformer at > 100° C

I think the mass they used is for automotive purposes and they weight a bit less because the tape that holds them was in the case, so i think that the weights have the right mass if they have the tape on them.
the 2 slugs you pulled out may be loading ballasts for the transformer.
if you have any more of them cheap chargers you may want to try testing them with and without the metal slugs and see if the waveforms change.
it may be possible that there are some varying quality of the transformers maybe even pulls from junk boards.
we see on other videos where people in china heat the boards over a fire and pull the parts and assumably to reuse them
wow perfect review and testing, thank you a lot . Good job.
Diode gone wild, thanks for your name
You don't understand, 65W is just the brand.
But the voltage/current rating on the label also claimed 65 W.
I love your videos. They are very informative and show the true side of the cheap china electronics.
If possible can you review the liitokala battery charger. They have very good reviews on ali express and are also of reasonable rate.
Seriously, this channel could be about anything, the study of a vegan poop/ fart Vs paint stripper on a Tesla, I mean anything..
BUT…
I watch the channel because of that beautiful cat. 😻
I love the Chinese products. If they don't work as advertised I simply report it on the store and immediately get my money back. If everyone did that the sellers would be punished enough to stop lying about their products.
I have bought high power usb supplies and they worked fine.
I was initially thrilled to buy this as Ali Express claimed it to be a 65W charger. On receipt, I found it to be a slow charger, cheap built and I told Ali Express. They are in the process of refunding me the amount I paid. At £1.67p, don't expect it to be of the original quality!
OMG A comedy charger. Solid state indeed, with wheel weights that need their own weights added, trouble is they would never reach their stated weight given this "standard". Zeno's bridge problem.
the added weight is only there to counter the antigravity effect
"A little bit suspicious, maybe!" Diode gone wild, 2024.
The conclusion is: dodgy, super dodgy or what? I can't figure it out by myself. Some part of me tell it's just dodgy from an general electrical safety perspective, but as the overall product, it's very dodgy. It's likely in between. We need to refine the categories.
It should be rated as SUPER SCAMMY of course)
If it weren't for those weights double sided taped over the board I might go with just dodgy. Those weights hanging there propels this device into the range of super dodgy though. Because there's no way that tape is going to hold forever. Those weights will fall off and short that whole device out.
@@1pcfred point taken!
I would classify it as: SUPER DODGY + SUPER RIPOFF.
it is a charger with an explosive power of 65W, they are not lying
Thumbs up from me after the "hell yes" 😅😅😅
Even has the yellowed with age look.
What happened to the molten air dryer?
The funniest thing is, that it actually does not mention the only thing it is really able to provide which is normal USB-Standarf of 5 V with 2 A of current , which is not even that bad if you wanted this.
Nice and very informative videos. We missed the "super dodgy" at the end. ;)
No video on your 65W charger??
yep, always do the weight test, if it feels uncomfortably light then return and give a 1 star review
Just found your channel and I can't help but subscribe, like and notifications on :)
Thank you, I will buy this charger for my bathroom. This way I can use my phone while im in my bathtub filled with saltwater :D
So just to be sure, it's better not to buy chargers from Temu, AliExpress, and similar marketplaces? And instead, buy something certified from local sellers? I bought a 3m charging USB-A to USB-C cable on Temu, which was supposed to be data-capable, but unfortunately, when connecting to a computer, it keeps disconnecting. When charging, my USB tester shows that only about 0.6A flows through the cable, while with a cable that's about 1 meter long and three times more expensive from a local seller, the current is around 1.2A.
Awesome test, thank you!
New hair dryer! Did the molten hair dryer finally melt?! ;)
0:27 that 100.0 grams (if you remove the wrapper) is just satisfying, someone surely engineered it to be that way :-)
These metal plates were actually alloy wheel weights.
But stamped with 'Fe' (element abbrev for Iron, from the Latin 'Ferrum')...
@@jnharton yes, as they are "eco-friendly" steel weights, instead of previously used lead ones...
@@TzOk Honestly lead weights don't seem like that big a deal to me, other than the element of deception.
As long as the lead is encapsulated/otherwise protected to reduce the risk of it leaching, it's hardly a crisis. Using them only in products with a long usable lifespan and recycling as necessary would be just fine.
If it weren't for the sheer laziness of humans (and purely profit-minded corporations) we wouldn't have half the environmental contamination that we do...
They're likely to be manufacturing rejects with casting error that couldn't be sold for the purpose, but it was cheaper to sell them as defective than to re-cast them.
I keep waiting for the day where Clive or DGW are going to take apart a piece of premium chinese engineering and see a note to themselves etched into the PCB
Merci !
i had an €1 counterfeit apple charger 5V 1A , it blew under 10 charges , and i charged an ipod nano , to give you a picture of the chargers performance ....
5:50
This chip supports 5 volts 2.1 ampers maximum
But becouse the loss, it is only 2.03 ampers
Lost it at "this is chinese 5 grams" 🤣
What thermal camera are you using? great resolution.
InfiRay P2 Pro, I've made a video about it.
@@DiodeGoneWild thanks Will check
Fantastic job, very thorough.
Oh great, thank you very much for such a favorable review, now I have to return 10'000 of those 🤣🤣🤣.
Few days ago, I receive this one power supply. And i don't have 10g and 5g weight. But some clay thing.
IKEA's triple type A 5V output dumb charger that BigClive reviewed several months ago (or a year) is safe enough, capable of long term 15W, and costs the same as this tested one - I bought one myself and think to by more, because well built simple chargers are dissappearing fast leaving only products of questionable quality in the cashiers area in the supermarkets while grate many things in everyday life don't need more power.
Thank you for making this video! Good quality video. Terrible bad Chinese product. Maybe check if the pieces of metal are radioactive, or if they contain anti matter.
I didn't know Borat started reviewing things
That looks like a very decent USB-C cable you have there, where is it from?
Which charger from aliexpress do you recommend? Im looking for one like 5V 3A 15W or more for example, thanks!
