And a ton of counterfeit power supplies. I font think you can buy a genuine apple or Samsung power supply in most of the world.

Thankfully a few weeks ago, I managed to buy a charger from LIDL supermarkets which didn't cost too much. It was £7.99 and features 5V/2.4A via USB type A, and QC 3.0/PD via USB type C (5V/3A, 9V/2A, 12V/1.5A). This one should be safe enough and hopefully won't blow up my phone.

And the 'good' manufacturers also glue/weld their devices shut so you can't even take a look inside if it's of genuine quality, let alone repair it.

I think it’s ridiculous to call a safe, well designed original charger for $20 “overpriced”. I think the extra $17 are a tiny price to pay for knowing that it won’t electrocute me or burn my house down. And it’ll likely be more efficient as a bonus.

@@arandomcomp2427 That’s the thing, in many places, getting original ones is difficult.

I was already suspicious when I saw it has an LED.

Whenever he says dodgy it sounds like douchy, but both words fit well xD

Before even turned on, I thought it is dodgy or even super dodgy 🙂

@@ACOnetwork And of course, what made it the best was the awesome construction of the transformer. :D

@@TheSpotify95 you do not need isolation, wire lacker is all that you need where fire and other hazards is non existent and completly safe and secure 🤣😂. Joke aside, that transformator can be used for one thing only... winding wires as jumper wires for the electronic repairs 😁... good at least for something right❓😁

Or "warp speed dodgy" :)

Yeah. Still waiting for that one that’s so bad that it needs to be rated Ultra Dodgy, with the skull icon on both sides. The ultra dodgy could be red text on a black background.

Good "spotting", Spotify95... You were spot on. And yes - Dang SCARY!! 25 bonus points awarded. Cheers!

I'm leaving for several days and I wanted to finish the video ;). That's why I didn't count it. But anyway, I counted dozens of them already...

@@DiodeGoneWild That piece of crap already took your valuable time. So cheaped out everywhere, I am surprised that even the USB socket has metal housing at all...

@@gabiold There was one in the previou episode that was even worse, and had literally everything wrong with it - including no isolation between any of the windings...

Great idea! There could be a nice firework with second charger.

You certainly should learn something about P.M.P.O. watts. Those are super puper uber zig zag mega dodgy.

This country has lost face to the rest of the world. Their reputation is ruined for a long time.

good point

Even if China export would exist it would be illegal to exist and the product would not be allowed to be importet

@@allcrafter3747 Chinese manufactures stick any European safety marks on their counterfeit and dangerous products to convince Europeans that their products are safe to be used in Europe.

I don’t think $20 for an original charger is “a lot of money”.

@@tookitogo $20 in the US is really nothing. But those 'cheap' $20 chargers become over 20% of the average salary in Brazil. Yes, folks, an original charger in Brazil can cost as much as filling your car at the gas station (currently, 33% of the minimum wage for a typical 12-gallon tank, which for Americans would be equivalent to paying 25 bucks a gallon). That's why those dangerous chargers are so popular, and even at that, there are even dodgier ones being sold for over $10 here.

@@LucasPereiradaSilva they shouldn't buy Iphone then if they cant afford good charger...

@@LucasPereiradaSilva Yet the cheap chargers are just as popular in places with high wages, unfortunately. :(

@@irfanyxp3489 it is not about an iPhone, if a Moto G or similar is "luxurious" for you, yeah, the charger of this phone costs just as much.

Actually larger ones like Samsung, Apple and other ones stopped including chargers in package (since iPhone 12 and Samsung S21), however on the other hand those phone require USB-C PD and or PPS (programmable power supply) so those Schnick & Schnack el cheapos like those on video will charge in snail speed. For instance with last super dodgy charger my Samsung S20 would be charging (3880 mAh accu) for about 4-5 hours, while with >= 25 W PPS power supply it is done in ~ 80 minutes and with 9V PDO or QC2.0 / QC3.0 it is charged in 2 hours. I was actually surprised when I received USB-C 20W power supply in iPad mini 6 (2021) box, however I had already Samsung 45W / Xiaomi 65W chargers + various USB-C notebook chargers (DELL, Lenovo, Apple), so I kept it as backup :)

Indeed, the fact that most phones (again, Apple starting this, so thank you...) now don't have chargers included, means that a lot of people won't want to buy expensive chargers on top of their expensive phone, so instead, will get the super cheap super dodgy ones. As in the ones that will eventually start a fire or cause an electric shock.

@@TheSpotify95 You're so right! And you know what i found to be the most ridiculous thing that apple has ever said in its entire existence??? "We removed the charger to combat e-waste, because everybody has at least 1 or 2 usb chargers already in their house from previous devices" . . . But what they didn't say, was that every iphone before that, used to come with a usb-a to lightning cable! But that is not the cable that came into the box when they axed the charger, they shipped a usb-c to lightning cable, which is completely useless for those usb-a chargers . . . So, in fact, they are creating even more e-waste! It's like they are laughing in our faces . . .

That ain't no paper cap... It's a ceramic disc cap... They are decent and reliable but not short curcuit proof.

@@westelaudio943 yeah I know. It's ceramic. I should've said that. I thank you for the clarification though. Learning new shit is what I'm all about.

There exist such comparisons, both in video and as text. The difference is night and day.

Look at previous samsung vs similar looking crap.

Pcb fuse😨

That plug will fit in Euro socket, French socket and old Soviet wall socket. It cover like 99% of usual uses.

Forget just the phone... if there's mains on the USB output, and you have a metal cased phone, then you'll get electrocuted by your phone/charger.

There might be a mistake in the schematic, the divider should go after the diode to get a DC value. The winding will output high frequency AC, but each half-wave would be different and malformed - not a sine wave at all.

Brazil is basically a scam, you must pay something like 80% of the product's price in taxes, and since the Brazilian real is worth nothing nowadays and taxes are charged in dollars (why would the customs charge you in some monopoly money like the Brazilian real?), anything over 2 dollars is instantly a luxury item. Brands like Multilaser love it as they pay only 2,5%, selling crappy Chinese products for prices that are closer to quality brands, basically what brazilians would call "camelô gourmet". If Lenovo makes a phone that costs 800, Multilaser comes with a similar one and puts a very similar price, even though they have paid something like 20 or 40 dollars for some dodgy white brand manufacturer in Shenzhen or Guangdong.

@@LucasPereiradaSilva por isso que eu mesmo monto os meus carregadores. Desde o meu primeiro cell phone, a Nokia , back in 1990's lol 1 good transformer 220-12-0-12v some fuses, diodes, capacitors, resistors a lm317, " *selector switch* " 《- _not sure about this component name_ . I still have my first charger, howerver, can't say the same about my black brick,🤣 i mean, my Nokia. 😊 stolen!!!! I even tried building chargers using the surface component technology but...,u know..., this is brasil ... can't find suitable paraphernalia to work with tiny components and, in finding, it is almost impossible to acquire due to exorbitant prices. Oh well!😩 Nevertheless the "old" technology " *não deixa nada a desejar* " in terms of quality and functionality. " *Até hoje, vira e mexe algum cliente me pede para construir-lhe algum radio AM* " . 🤣 ✌😊👍 💚💛💙 🇧🇷🇧🇷🇧🇷

@@LucasPereiradaSilva quase esqueço. em 1994 quando adquirí meu nokia aconteceu um "acidente" . O carregador simplesmentw derreteu na tomada. Por isso eu decidí consteuir meu próprio carregador. O qual tenho até hoje. ✌😊👍 that' s it.

Meh... What is likeable in it, the star pattern? Probably that, and the two LEDs illuminating it is where all the "engineering" went. Otherwise every part of it is the chepest and crappiest possible. I am so angry that this and a lot of similar piece of garbage can be sold, or imported at all in the first place! There really should be some regulation that holds the sellers responsible, otherwise it seems that manufacturing this e-waste can not be stopped.

Yeah it looked kinda cool.

@@westelaudio943 Your house will also look cool, when firemen get their job done.

Any charger whose transformer has no isolation at all (except the lacquer on the wires) is automatically going to get a super dodgy rating. Over time, the transformer will run hot, the lacquer will fail, the windings will bridge over and you'll get mains on the USB port(s).

That first charger was actually fine. Very basic, but OK. Second one indeed was deadly crap.

@@KrotowX Exactly my thoughts. I was kind of nicely disagreeing with the "dodgy" claim on the first one :)

contact me at danyk@centrum.cz ;)

I think a long time ago I opened a 12V car cigarette socket USB charger.

Car phone chargers are not likely to be dangerously-dodgy because there's no high voltage, no need for isolation which is the common culprit in the mains chargers - if the charger melts it'll likely just trip a breaker, but if the isolation is bad your phone will get mains voltage (with a bonus of enough resistance on its path to not trip a breaker while it fries the phone and the cable)

I had mini GoGen car plug 1A charger with USB socket and hardwired microUSB cable that fail. I hear some bang not very loud and smell something burnt but blue LED still lit. I'm very happy phone was not connected USB output was above 11V and above 13V when engine running. When capacitor explode probably shortcut control chip. 1V drop probably because diode and switching transistor.

Here is video with combo power socket and car plug charger in one "Questionable 2-in-1 USB charger - test, schematic & modifications" and "DashCam Test & Total Teardown (including car charger)"

are you kidding me gaaaays :)

People have done those comparisons and the difference is day and night. The big manufacturers don’t take _any_ risks.

I think that's less likely because they would probably need larger lengths of wire.

For what reason?

@@Konstantin_. seeing if they can handle it

@@kasel1979krettnach no household appliance/phone charger is even meant for 400vac, why do u think that this could handle it

@@Konstantin_. because it likely can.

@@kasel1979krettnach But we know it won’t, because in both of these chargers, the input capacitor is rated for 400V DC, but the rectified voltage of 400V AC is 566V (400*1.414). The cap WILL fail, and without it the charger cannot function.

Probably nothing.

1 hour to 10 hour shouldn't matter since there's not much space for heat accumulation. I suspect that most heat related failures are when running them near the cutoff current, because those control chips usually include short protection.

Without it the high frequency switching noise will have no return path and will instead radiate out from the cables causing EMI problems.

Basically you can think of the transformer as an nonideal isolator, because the prim. and sec. windings form a "capacitor" which can pass high frequency AC which is still part of the mains curcuit. This is so weak it can't hurt you but it will seek to return to mains earth and radiate off of everything along the way. So this interference cap is put in to short it out before it reaches the cable.

@@westelaudio943 without it It can create any problem

@@niloypramanik3 Not really other than intruducing noise to nearby radios, TVs and other devices, but it's advisable to leave it in there. If the cap is dodgy you can replace it with an appropriate one.

@@westelaudio943 which cap is best for this(value)

The charger would just probably shut down. I guess this is one interesting features of these crappy supplies. May be related to the fact that the control chip gets its power from the auxiliary winding - and the loaded secondary starves it so the chip ceases oscillation.

Another failure mode - a permanent one - would be the secondary rectification diode overheating. It did happen in the past DGW's tests as well. But it's much more rare, usually shutdown comes first.

No "tyu" :(
