Dangerous USB phone chargers 4

Another collection of dodgy USB phone chargers from eBay that may cause an electric shock or fire. They also tend to have a poor interference suppression, poor output voltage regulation and a fake current rating.

When you go to next screen on your usb tester there's charging mode information - quite useful to see what current charger says it can deliver

[@Broken_Yugo]

Protip: If it plugs in the wall, buy it from somebody you can sue. They're only likely to sell you crap, not hazardous crap.

[@bramvandenbroeck5060]

I take those dodgy chargers from people who found out that those chargers are a deathtrap, i use the components inside, i re-purpose the caps, resistors and transformers, but not in any circuit, i take the transformer appart and i use the lacker-wire to use them as jump wires on broken devices with cracked traces

[@Chuckiele]

"Lets test it and then open it to see if its safe" I love you :D

[@zidane2k1]

I like how things that are typically part of quality switching power supplies are "luxuries" in these cheap dodgy chargers

Bloody hell! It's a disaster! That pseudo fuse is comical

[@Gersberms]

Thank you for clarifying the capacitor safety codes, I've been looking for that. So I can safely use Y1 everywhere if I only want to buy 1 capacitor type?

[@mohammedissam3651]

Great content. Well done keep posting .

[@sahriarjihan220]

finally, I was waiting for this by the way ( I find peace in your videos) lol

[@jg6780]

It would be interesting, if you would test the break down voltage between the windings before teardown of the transformer. For example with some simple hvdc converter an resistor in series to see at which voltage the varnish fails. Perhaps they are using a thicker varnish on the windings, and it works. The main danger comes, when the winding is hot anyway.

[@Silas155]

How about try this chargers with 500V to test insulation and then disassembly them. It would be interesting to see leakage current from mains to 5V rail.

Those cheap pcb fuses might look cheap, but they are suprisingly effective as a low cost short circuit interruptors

Please make a video of the voltage regulator next it's looking really interesting, is it a ferroresonant one?

You are freaking genius :D

[@indiandiyboyby-kanishk76]

Now I can repeat his dialogue *_niceeee_*

[@seanman6541]

A few years back I purchased a super cheap charger from ebay for the purpose of dissection. I was hoping to learn a bit about creating a discreet flyback converter since most of the chinese power supplys don't contain any dedicated SMPS ICs. Much to my surprise, it wasn't even a flyback converter. It was an f'ing buck converter. A BUCK CONVERTER. Absolutely no isolation from the mains. Even worse, if the crappy BJT fails shorted (which most do), the full mains voltage will appear on the USB port. Beyond dangerous.

[@BlockyYT1422]

I have the second one. I tried to use it with an usb led light which draws ~0.71A. After a week with a few work hour every day, the secondary green Sanyo(?) capacitor heated up and blown, melting a bit the top of the case.

[@Waaasil]

[@hernancoronel]

Thank you Diode! Love your videos!

[@vaclavtrpisovsky]

In the second one, how is the isolation between primary contacts on the main board and the tracks/ports on the "daughterboard"?

[@scienceguide3880]

I hate that China blame my country made (Viet Nam) and they forgot 1 word "i" in "Viet Nam" not "Vet"

[@l0k048]

it's not China, it's the manufacturer that claimed it to be made in Vietnam/China

[@Edward-ft6sh]

@@l0k048 It is made in Vietnam with Chinese technology, and the company's owner is Chinese.

[@TheSpotify95]

Definitely looking forward to this one! Yeah, none of those chargers are what I'd purchase :p

[@BRUXXUS]

I may have missed something, but how did the first one know to shut down when over current?

[@103rdBlackVulture]

All of your videos just ROCK!!! Can you also please suggest a book on SMPSs, if you haven't done so already. Thanks and keep up the good work! P.S. we use the same oscilloscope but mine is with english language on the front panel. Found it years ago in a flea market here in Greece

[@TechnoMasterKyiv]

Thanks you. A very well done job. I like and subscribe to YOUR CHANNEL.

[@Enderkruemel]

The board in the last one says it is only 1A and also the print under the capacitor says CY1, there schould have been the right one,But i think it was too extensive for them

[@t_Gecko]

Wohooo new video!

[@ritzevespa]

Je klinkt als een sjeng oet mehstreeg 😅👍 nice vid haha

[@puriap250]

Awesome teardown and explanation. Thanks. How does the first one work without a controller IC tho? Doesn't the switching transistor need a pwm signal?

[@309electronics5]

Sorry for being to late but the circuit has an auxiliary transistor and the auxilary winding acts as a feedback to drive the auxilary transistor and that drives the main transistor you can see it in the schematic

[@miranlyan1]

I completely agree with you you are right good job man

[@Zebra_Paw]

It is only the third episode, not the fourth... In the second episode, you reviewed exactly the same charger as the second one in this episode, but in black version!

[@DiodeGoneWild]

well, the episode 3 was renamed to "Good vs. Dangerous USB Phone Chargers" because one of them was good :).

[@Zebra_Paw]

@@DiodeGoneWild Didn't know it counted! But then in some videos you reviewed one specific USB charger, shouldn't they count too?

[@AnujArya_Curious]

The higher voltage near the charger can also be due to the inherent cable drop compensation featyre built in to the smps ic now a days.

[@uzaiyaro]

I love my Ruining USB testers. I go through a few if them because I use them so damn much. I want to order a few more at some point soon. P.S. Those ruideng analysers are able to show you the resistance across the data lines. It would have been interesting to see.

[@Pirelli.]

we wait patiently for the number 1 👉🏆😊

[@crusaderanimation6967]

So... since you done video when you showed how to wind transformer properly after showing how it was done poorly. Maybye after all those dogy chargers would you make video when you design your own USB charger ? PS. Just suggestion for topic for video.

[@DolezalPetr]

made in vetnam, hmm that sounds screwableeeee

[@teslakovalaborator]

it requires agent orange

[@scienceguide3880]

China did and blame to Viet Nam

[@peterkutak]

is the nice blue 1kV capacitor just fake or is it safety capacitor for 110V?

[@SeanBZA]

For that series ballast driver transformer you will need to get a few 125W mercury vapour lamps to put in series, to see how it does the voltage regulation across the 4 series lamps.

[@tvelektron]

Hi, thank You a lot, it is very entertaining and a particularly important topic. But on the other hand we all are searching "nice" ones which are cheap as well... Chris

[@andricode]

I once found a fake samsung one that claimed 5V 2A, of course it was just 800mA and it had a dead weight to simulate complexity, but it still was too light anyways
