The power supply gets so hot that the sticky tape could fall off and the steel weight could short something out

The fact that they skimped on the 0.5 gram in the 10grams weighted plate is amazing.

I love the 10 gram weight weighing 9, 5 grams. Is nothing holy any more???

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!

6:03 i love how you announced the melted hair dryer as if it was standardized equipment for dismantling a transformer.

I love the 1.5 mm² wire as the pointer 😂

Respect for the solid-core pointer at 2:50 o7

Cost of components 5$, cover 4$, shipping 30$, tax and duty 3$, customs fee 5$, but they do all of it just for $3.

A remarkable and masterful forensic analysis: one of the best examples of technical communication I have EVER seen!
Carry on good sir!

[pawees]

it's straight forward - "120W" is a brand name :-)

We need more of the cat's opinion, I'm here for the cat.

“Let’s cut the corner. It definitely contains a lot of cut corners inside of it anyway!” Excellent summary!

thank you for explaining everything super fast. other youtube videos will take to do all this like 3 moths duration. keep it up bro 😍

Next time, maybe you could also try whether the resistor is actually fusible?

[WiyilFurato]

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.

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.

2:40 "chinese 10 grams are 9.5 grams" this is deep truth !! very deep

Making a post to sate the hunger of the algorithm deity.
You have a really nice cat. *Thank you* for sharing. 👍👍

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.
