There is a hard technical reason to do this with mice in the past - tracking acceleration limit on optical mice sensors. By adding weight, you limit person's ability to accelerate the mouse and prevent the sensor from misreading and "spinning out" where the read direction is completely unrelated to real movement direction, usually an accidental singularity determined by highlight direction or spot unevenness. Now since early 2010s semiconductor manufacturers make dedicated gaming mouse sensors which can run more DSP passes per frame and thus have a larger range of valid accelerations, and successively the weight could be reduced without the sensor losing tracking under high performance use. The very first optical sensors like 2610 could only track 0.25g acceleration. Then it became common that most sensors could reach 10g, but you can still lose tracking on these sensors. By 2016, 50g mark was reached on high end sensors and weights could be removed. When i played Unreal Tournament 2004 and other high movement games competitively, i would sometimes exceed 15g rated sensor's tracking capability without the weights, but i cannot exceed 30g, not even close, though there are players with more athletic arms than mine.
@@SianaGearz Interesting reasoning, I never opened up my Intellimouse Explorer 20 years ago but it was very easy to move it too fast and lose tracking. The MX518 later on was much better. Lighter weight is definitely preferable though!
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!
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.
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.
@@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.

@@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.

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.
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.
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.
a friend of mine once got a USB charger from a questionable source. he got the full knocked out of him one day with it. turned out one side of the USB was connected directly to one side of the mains. it's a wonder it didn't fry his telephone
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.

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.
@@1pcfred Absolutely not. 5g weight has a shortfall of 0.7g. You would need to add more than half a cubic centimetre of high density plastic - or more than a cubic centimetre of foam acrylic tape - to make up the difference. Many times more than the volume of the iron weight itself. The disparity of 10g weight isn't quite as drastic, and still not nearly enough by an order of magnitude for the adhesive to make up for it.
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
If you have a few Euro coins, especially ones that look sort of fresh-ish, you can just calibrate the scale, since they are cast precisely and are taken out of circulation when it starts wearing down. I'm sure DGW knows better than to blindly trust a scale from Ali. But usually the factory calibration for reasonable weights placed well in the middle is pretty good, even on a dodgy scale. Sometimes the load cell is badly cut and you get different readings on different corners, but usually the discrepancy is tolerable. Sometimes the load cell is overrated and at the high end of the scale, well beyond about 200g, it starts distorting the outcome but still not by THAT much.

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.
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.
PLEASE update your fnirsi FNB58 firmware, your ancient version lacks a lot of charging protocols.
I am actually using this exact charger. It does the job for normal/slow charging.
However, I always unplug it when I'm leaving the house, lol
It will protect your smartphone from too high charging currents, your battery will last 10 years.. before being charged 100%
This was one of the most hilarious teardown you made!
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.
So the conclusion is: SUPER DODGY!
i stumbled with this video and i have the same one connected to my wall. it doesnt charge fast like promised but it was cheap as dirt lol.
a friend of mine once got a USB charger from a questionable source. he got the full knocked out of him one day with it. turned out one side of the USB was connected directly to one side of the mains. it's a wonder it didn't fry his telephone
Even the weights are not up to spec
Were is the video about that black charger? I want to see. 😀
Charger is getting hot I purchased from daraz nepal..2 whole black gan charger. 65 watt
Probably it has a protocol you can't find, the charger speaks chinese so your device can not negociate
This is so sketchy. Don't cheapout on things connected to mains voltage folks.
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.
@@jnharton It has a single Type-A output.
For the price, it's not bad. But lying about the capabilities, that is low.
It's bad. You can get Ikea 5W charger for the same money with much higher quality.
@@hojnikb but this charger puts out 10 Watts. Not that I'd ever want to use it with those weights hanging over the circuit board. I know what heat does to that kind of adhesive. At least throw some fish paper in there.
The charger is super dodgy or dodgy
Is the chip is really made with gallium nitride 🤔
Should be gallium nitride (GaN). Gallium Nitrate would be Ga(NO3)3.
NO3 -> 1 Nitrogen, 3 Oxygen (Nitrate)
@@jnharton thanks
People buy £1000 phone but uses £5 charger are stupid people
Where is a stamp!? 😀
Can anyone explain how this garbage has over 4 * rating on aliexpress? are there paied reviewers like on amazon?
People don't understand electronics - it has arrived, they plug it in, it "works", they are happy. but YES there are fake ratings on Ali, you will spot them sometimes.
Ill stick with my apple 10w chargers
What have I just witnessed 💀
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.
The arsillicness of Lysenkoist communism knows no bounds.
your accent makes it seem like you're constantly singing no offense
If they advertise it as yellow that would be the only truthful thing about it.
Chinese 5 grams = 4,4g better than chinese 65 watts = 10W
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.
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.
They watched Snatch? Weight is a sign of reliability. 😅
by far I think it's the worst on your dodgy charger list, perhaps even among the super dodgy ones😂
It was those weights that really put this unit into its own category. The transformer was surprisingly well constructed though.
chinese iron weights :) they are not event 5 and 10 grams aahahhahaha
They probably were with their adhesive backing. That weight counts too, you know?
@@1pcfred Absolutely not. 5g weight has a shortfall of 0.7g. You would need to add more than half a cubic centimetre of high density plastic - or more than a cubic centimetre of foam acrylic tape - to make up the difference. Many times more than the volume of the iron weight itself. The disparity of 10g weight isn't quite as drastic, and still not nearly enough by an order of magnitude for the adhesive to make up for it.
@DiodeGoneWild Danyk, today's video lacks a final evaluation, so I was looking forward to it. 😥
You know it's fake just by looking at the specs not mentioning 5V or the massive amperage at 9V.
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
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
OMG what happened to the old hairdryer? Could not fix it?🙁
I just saved this one that was heading to a dumpster, so I wanted to test it ;)
ironically they didint even bother to list a 5v output on the charger with fake weights
The only thing it CAN actually do, they seem to need to lie about also....
Weights added to make the device heavier, what a cheat. Great autopsy and device analyses.
no GaN at all. GaN transistor will need a large heatsink
it is a charger with an explosive power of 65W, they are not lying
3:30 These are chinese weights... on a chinese scale! Which one is incorrect? The weights, the scale, or both?
If you have a few Euro coins, especially ones that look sort of fresh-ish, you can just calibrate the scale, since they are cast precisely and are taken out of circulation when it starts wearing down. I'm sure DGW knows better than to blindly trust a scale from Ali.
But usually the factory calibration for reasonable weights placed well in the middle is pretty good, even on a dodgy scale. Sometimes the load cell is badly cut and you get different readings on different corners, but usually the discrepancy is tolerable. Sometimes the load cell is overrated and at the high end of the scale, well beyond about 200g, it starts distorting the outcome but still not by THAT much.
I replaced the OEM (expensive) Xiaomi "turbo" smart phone charger with low-wattage Hama. Too fast and furious for my liking. Also too hot.
I didn't know Borat started reviewing things
On the plus side, the PCB had great primary to secondary separation.
To bad it was shit, i loved the color of it.. 😛
Ah, the "Quality-Feel Chunk-of-Steel"! The mark of a real quality product, as all chinese manufacturers know.
Big Clive - Swedish Chef edition?
Even has the yellowed with age look.
