Dangerous Chinese Travel Extension with USB Charger - teardown
ฝัง
- เผยแพร่เมื่อ 20 พ.ค. 2018
- Today I made a teardown of a travel power extension socket with a USB charger from China with a picture of a mouse on it. It has a mains plug, a cable, mains socket and 4 USB sockets. It immediately looks quite dangerous because of a very thin mains cable and a 3-terminal mains socket, despite the mains plug is just 2-pin non-grounded. The ground (earth) terminal doesn't go anywhere. The charger can't continuously supply the claimed 4.8A current and the mains isolation is questionable. Risk of electric shock and fire.

8:06, a diode gone wild 😉
HDXFH 😂
Diode gone fat
@@Yelawolf269 This diode from grandma
It looks like a 10A10 Diode. I looked it up! It's used as rectifier.
O. L. L ,
You are a great electronics TH-camr. I don't see how you don't have a lot of subs. Keep up the great work!
Thanks :). For me, 62k subs is a great achievement.
Not whirlpool. Their tumble dryers burst into flames without warning.
DangBoyIsCool subbed
deserter who fuck family czech language for few money......
What does that even mean Asshole...one of my fav TH-cam's ever wish he would sbowface
That blue mouse logo looks awful
That's a blue coala
I thought it was supposed to be deadmou5😂😂😂😂
Or even stitch
It looks like Mickey Mouse on cocaine
Fan universe i like your ventilation fan video so much
They really went wild with that big fat diode
Chonk
The mains socket should be fused if it's rated to only 800w. Accidentally drawing too much current will start a fire, but may be not enough to trip a breaker.
That's right. Every extension strip should have a fuse or breaker built in it, unless it can handle the full current of the circuit breaker (16A in Europe).
Yes, British sockets have a seperate fuse in them@@DiodeGoneWild
The cable for those cheap extensions are usually mad of copper cladded aluminum, and not pure copper.
Because copper is expensive metal.
So, the actual resistance of the cables can be much higher, and they can handle much lower current.
Even the metal pins (prongs) of the plugs can be made of steel and not made of chrome plated brass.
I have even seen that the metal pins of the plugs are made of very thin brass tubing with plastic core filling!
Chinese they don't care about safety the only thing they care about is money!
China is filling this wold with unsafe, toxic and garbage things.....
25:06 "attracting children's fingers to those holes" hahahha :D
Cheese 1337 lolololololololololooolooollllollol
*MP5*
*US plug*
Oh
XD MP5
“MP5” actually refers to PMP (Portable Media player) which can run games from multiple platforms and play media files.
Zone Tan Also, yeah xD
@@Riskteven thats not what he meant but ok
@@Riskteven No not like that. He actually made a gun joke.The MP5 is a gun and its kind of a running joke with the US and its gun culture.
High speed USB speed I'm dieing lmao
Finally, something to recharge my smart SMG with.
The 800 watts claim is very dubious. I would like to see that tested. I would guess it would kill it and start a fire.
I plan to test it :). I hope so (in order to make the video interesting :D) !
Or artificially make the power factor worse.
NE 555 😂👍
It is obvious that this was an intentional ,,TYPO,, It suppose to say 8 Watts or perhaps 18 (@most) This is a joke right ? 800W Yeah........800 watts my (**mm!!!) right...:))
At 800W it goes up in smoke, see the follow up video ;).
“BIG!” On the schematic near the diode 😂 Great video as alwais!
The idea of this charger is not bad, but the realization is bad!!!
It should have a thick 3-wire cable and a grounded plug, but then it's not so compact and you wouln't be able to wind the cable around the strip. Unfortunately such a slim sleek portable design interferes with safety...
It's time to start calling these piddly 1kv caps 'DEATH CAPACITORS'
Big thumbs up on the whole channel There is so much valuable information in this video and it goes by at such a clip it needs to be rerun over at least 2 more times.
Love all your videos. You make them interesting not only for those who understand circuitry. Keep it up please :)
The name of this channel should be "Chinese gone wild"
EVEN MORE SALT!!!!!!!!!
@Tüplü_Şahin Congrats, you have no sense of humor
even more sAs
Dude, they should hire you as quality management.
Big Clive, who has his own TH-cam channel calls this type of adapter the deathdapther because you can push the UK style plug earth pin intonthe live on them.
Your hand-drawn schematics are true artwork ;-)
The mouse in the thumbnail looks like it's puking
I absolutely love these videos and the accent makes it that much better! 😉👍
You really like that big diode LOL (it's R-6 or P600 package I think), love your videos 👍👍👍👍👍
Fantastic analysis, fantastic calculator, oscilloscope and 🐈!
Great inspection and explanation as always! I like the cat in the last minute when it seems to follow your explanations. But it seems she got boring very quickly and moves its head away before trolling away. Probably an excursion about meat would be more interesting for her :-)
As always an awesome analysis - děkuji / thank you!
that really is a fat diode, I dont think Ive ever seen a fatter one
You once made a video about a high voltage module, but it was broken. Can you do another video with a working module? I would like to see that very much, and I love your channel😜
That's really a wild diode
'Dangerous Chinese Travel Extension with USB Charger Teardown'???
More like Chinese Travel Death Trap Teardown!
Excellent video, as always, DiodeGoneWild
High speed usb speed... im dying right now hahahahahaha
It's not a USB hub :)
IT'S A CHARGER
3:49 This happens in the US with most power strips and extension cords too! At least it's only 120V instead of 240V. Still dangerous, but at least the dying process is less painful.
Dear , I found all of your vedios are very informative and very interesting. But one thing is there always in mind that why you keep your channel name Diode Gone Wild...plz reply.. And Do keep your great job going..
Thats some wild diode!
And i thought it was a mouse killer lol, what on earth is a mouse got to do with charging??.
Mad people.
The cable looks like a headphone cable or similar, that's frightning at 230v :-(.
Pity you can't fix it and change the usb resistors to tell a phone say 1 amp per usb and remove one usb socket, it would still be usable.
The earth pin is just so stupid.:-(
Neskutečné! Od začátku co vás sleduji si říkám že to zní český a teď se mi to potvrdilo! Parádní videa!
Definitely you're the best stuff reviewer ina very simple style. And the best, is your English accent.
11:41 Plot twist: the cat reverse engineered the schematic for him!
I love your vids!!!
WOW... Half hour of "dangeroos and doddgy" stuff... THANKS Danyk ❤️💋😘
DiodeGoneWild: Dats A Very very fat diode
Me:That Diode Ate A Small Electroyte Capacitor....It’s marked 3040 Too....
I need to buy your fire extinguisher, does it come in a six pack.
Yes it does.
Just go to your nearest shop and search for 🍺
9:51 mew
That diode has gone wild!!!
"waaoow that diode" you said. lol
The bypass diodes on solar panels are not for reverse voltage, they are there to make the solar panel work even if a small portion of the panel is shaded. It will give a lower voltage but it will still work good enough with that bypass diode over the shaded element. That`s why it`s called a bypass and not a protection diode mister Diagonal Wild.
Buy cheap usb sticks from ebay see if their capcity is real.
How much this charger cost? I think it is a good replacement for my dry cabinet power supply module. I have seen many similar faulty cabinets for saie in my local "ebay". I tore open one module and found that the parts were undersized and rated, no wonder many failed. The power module is "rated" as 3.3V, 6W but on the pcb, the switching transformer is a tiny winny job and 1N4007 diodes are used in the dc output. I checked with the module manufacture and the cost quoted was US$20. The module is totally resin coated and I had a hard removing all that stuff.
THIS WAS A *SHOCKING* VIDEO!!! 😱😱😱
ElectroBOOM
That isolation transformer and the proximity of your arm to it's terminals freak me out!
James Searle at least he should sit it upside down on his desk, so live terminal not exposed.
I'm going to go ahead and say that that diode is not what's overheating, considering it's a 10 amp diode running at less than half it's design load.
That switching chip is definitely at fault - I would say that if you were to replace it with a higher power chip, or stack two of them (with some way to get the heat away from them) it would probably be fine. That capacitor would probably have to be replaced as well. If you're really worried about tracking, you could also always use a piece of plastic between them for guaranteed antitracking at those voltages.
If the cable was replaced with a much thicker one, and a grounding pin was connected properly, it would probably be perfectly fine.
But then it wouldn't be as cheap.
Can you make a video about inverters?It will be very helpfull !
Ahoj, raz dávno si robil video na elektro deodorant, aj si ho používal alebo bol len na test? Aké sú sním skúsenosti a či funguje. Vďaka
Great vid as usual but you don’t have to read everything out on the packaging bro,
Dan, i want to build yours SSTC IV. with IGBT because its really powerful but i would like to modulate it with audio, also i dont have that igbt in my country, i can get hand on only IRG4PC50W or IRG4PC50UD or IRG4PC40KD. Can i use those IGBT's as replacement and interrupt oscillator with audio signal? Can those IGBT's handle rectified 3 Phase DC? Im asking this because im just a student and i dont want to blow up igbt's right away, i wound secondary 1m tall with 0.2mm wire.
can you please fix the white balance setting in your camera and set it to manual. almost in all your videos the color goes yellow several times during the video
yellow is better than blue
Nice cat and nice explanation
It is just a USB charger, not an extension cord. 3040 diode can gone wild with 4.8 Amps load.
They started selling these now in a local store
9:50 cat meows
sir, can you review about portable mini fan from chinese ? it look weird when 3 of my chinese portable mini fan won't work...
5:30 Current is smaller due to lower voltage even when it is 0,1V of change. Because of constant resistance of resistor when voltage is smaller current too is smaller. Current(a)=Voltage(V)*resistance(Ω)(I'm writing for other people i'm 100% sure you know it:D)
Alright, MP5... That is freaking gun! I don't know Chinese charge weapons. 😀
2:08 They could save ink by omitting the second half of that sentence. That might improve the safety as well.
At 11:44 after a single glance at the circuit board Veritaska the cat draws the schematic ready to use
The reason why they might have put the grounding piece of metal in there is probably because there might also be a "luxury" version that is actually grounded.
For the first time I saw a Chinese charger with a fuse and a high quality circuit board for mobile phone charger on his channel.
could you please show us an electronic device correctly made? Like with ground connected somewhere, PCB design etc.
The mouse gives a false sense of reduced doggedness!
Is theare triger holdoff option?
Could you give me the link for the extension cord?I am certainly not interested in the sockets,but the charger is quite interesting.
It's this one:

Thank you
For your safety and relief for the viewer, could you please isolate the makeshift isolation transformer setup? :D
Thanks for your videos, I love watching them. Your way to write the A and W is completely unique to me, I kinda like the style!
Oh and by the way: If you take it strictly, there are no "Amps". It's Amp(ere), there is no need for a plural form.
That old school Soviet scope is so awesome. Great video. Thanks for sharing.
Upvote for the cat :)
Nice review.
"made for mp5"
whoa
I'm the trouble starter, punkin' instigator
I'm the fear addicted, danger illustrated
I'm a firestarter, twisted firestarter
1:23 Chuckled at this part when he says "Mp5".
What is that you are building on the bread board in the background?
Isn't it the makeshift thermometer I was using to measure the temperature of the Pirl Charger?
Ah, yes. I remember that video.
I'm planning to buy that charger aswell.
Chips seems to be DK124 or DK125.....just a guess!
The thing could handle 4.5 amps before going off in flames. I'm going to be totally honest here, ungrounded death trap aside, thats a lot better than I expected.
ye really 4.8A from a noname chinese charger? wow.... i not expected that! too sad its overheating :D
MP5? is that actually a thing? or are they talking about the H&K MP5?
Good review.
The chip seems to be the classic Viper22A.
Why there is a grandclock soud in the background?
Ого российский осчилоскоп-wow russian osciloscope☺
Он ( пацанчик ) Чешский )) тут у нас много осталось советского/русского ))
I have never seen this charger before
Hi,I was wondering, why they are using only 1 diode instead of full bridge rectifier?
That's normal in Chinese
9:50 meow 😂😂
You are on many videos saying about necessity of "isolation distance on the board" (between primary and secondary side of board) but nowhere you are explaining (at least what I watched) why there even need to be some distance gap.
@chudzo skruo
voltage surge or dampness (humidity) can cause the high voltage to jump the small gap , also the transformer needs good insulation between windings for the same reason :-)
Pěkný rychlozabíječ.
Was waiting for Smoke...lol
MANDINGO DIODE
Magical smoke vomiting travel mouse :)
There is a word I usually dont get it "The Snapt Network" something like that, what is it
Snubber network
@@versedbridge4007 thank you 💪💪
That Diode from a Tank...lol
Only been watching less than three minutes and I'm *very* glad this thing doesn't come with a UK plug
If you test this thing for a long time it will probably melt with 4 amps load
Thank you.
Great in-depth review!
