Especially at 3:16 ... the fuse is actually the device you're connecting to this doggy charger.... it's very "Dangeruuuus!" lol

NUMER ONE !!!

😃 my feline fellows

Ginger Kitty Project This isn’t related to the comment but I love ginger kitties too! I have one named Todd.

Cannot beat a good pussy! >;o) The old ones are the best!

I think he is recording on his cat bed

@@mrkitty777 Greetings.

back to 80s?

so..... he need more *SALT?*

@@hyzadhanafi7419 even more salt

Lol 😂

Still a good house burner

Excellent. However - yours is just an isolated case

This would be a very good idea!

For high frequency transformers the kind of physical isolation you mention is not an option. All international standards that I know of accept 3 layers of tape (not ordinary stcky tape) as a suitable barrier "through insulation" but they also require a clear creepage distance between primary and secondary of at least 6.4mm or 8.0mm for the German standards. The same creepage distance that applies on the PCB between primary and secondary circuits. While this video found some better power supplies I don't think he found even one that actually meets safety requirements. It is a sad thing when all you can hope for is a thing less crappy than the alternatives. ;-)

lol yeah

i would buy merch from him....

@@pdavidp4563 what you mean? I WILL buy it! Not Would

BTW: The black Samsung charger is definitely a FAKE. The model number is EPTA10EWE. The W stands for white. AND THE POWER SUPPLY IS BLACK.

I would buy a shirt

Also his videos are very educational and he is making us careful about safety.

@@FaysalKhalashi yeah!

I have added the word Dodgy to my vocabulary.

Yes, that is a clone, it would have probably been a Samsung that they just copied and called it Origianl :p

So true. BTW: The black Samsung charger is definitely a FAKE. The model number is epta10eWe. The W stands for white. AND THE POWER SUPPLY IS BLACK

A long time ago, I bought a cheap (4$) charger that is supposedly a Quickcharge one, has two USB 3.0 outputs. I had more expensive chargers that got "tired" in less than half a year but this one just keeps on going..

@Alex Tarasov dodgy stickers? You mean with phenol? 😂

not all of the ones made in china are dodgy, some are.

@@jort93z Correct!

Agustinus Reynaldi example even oem legit chargers are made in china

@@jort93z Not all of them are dodgy but most of them are really super zuper dodgy, easily broken by itself, and don't care about user safety. Assembling is different with producing. But both of them are labelled Made In fucking China.

Most (if not all) chargers "dodgy" or not are made in China.

dodgy!

Czech or Indian ?

@@MrSamsyria Czech, he's not Indian lmao

It just triggers me ah

in first 10 seconds I thought it was intentional...

This doesn't have to be a rule. I have seen old power supplies in CRT monitors, they were about 50W and still made of just 2 or 3 transistors, no chip. A lot of switching power supplies are repurposed. It's easier to reuse an existing design and board layout and just change few capacitors, resistive divider and number of turns of the secondary winding.

@@DiodeGoneWild True. I should have clarified. I meant specifically with these cheap USB power supplies. You can always beef up the non-IC design with more power transistors, but there's only so much room you have in a tiny USB charger case. :)

i dont think 120V is any better xD

120 V is not safe. Americans think it is and there are horrible number of deaths as a result.

The way he said: "Nice" is really nice... 😍😍😍

Because he wants to use them after teardown?

@si Markeyan Not so. I bought two chargers from IKEA, and took one apart. It was of very high quality, not like the internet cheapies. Apple chargers are the best; buy directly from an Apple store and you will not get a counterfeit.

If YOU import items into the country it is YOU who are responsible. It is not practical for anyone else to open the millions of packages that arrive every month, examine the contents, and conduct electrical inspections and tests. Unless of course you want ALL private imports to be banned. It is not permitted for retail shops, mail order companies, or other suppliers in the U.K. to supply any electrical item that does not meet the U.K. electrical safety requirements. It is a similar situation in other other first world countries.

@@Mark1024MAK thanks for the reply. I've purchased off eBay and the product started to smoke so I was lucky to be on hand to turn it off. I had my money refunded but I don't think they'd pay for a new house. The C E mark is not a safety mark only China export I found out. Certainly buyers beware.

Jeff Cole - Fake products and unauthorised look alike products often are marked with or described by lies, misleading descriptions and copied trade marks, copied certification marks and similar. All of which are meaningless and are only there to help make the items look good.

Jeff Cole - just to see how bad some power supply units / adaptors / chargers were, I bought some from eBay some years back. I deliberately went for some of the cheapest. All with pins suitable for the standard U.K. three pin sockets. And all being sold on eBay.co.uk in our currency (£’s). Construction quality inside the units was terrible. Just like some of the units in Diode’s video, there were multiple problems. Poor quality components. Inconsistent values of the capacitors - from the same seller, the lower power unit had higher capacity capacitors than the higher power unit! Either the Y class safety capacitor was completely missing, or it was a normal non-safety capacitor. Cheap PCB. Mains wires that could touch the low voltage output circuitry if they came loose from the solder pads on the PCB. Nowhere near the minimum required isolation clearance between mains voltage circuits and the low voltage output circuitry. No fuse, no inrush limiting resistor and no interference filter components. Poor quality transformer. Case screws that were so small that one knock and the cover could come off. Basically, they had been made as cheaply as possible.

Fun fact it's not allowed. But somehow nobody stops the guys who sell these here locally. These dodgy charcheres can be ordered via Alibaba directly from China in packages of 50 or 100 units, for less than 1 $ per unit. So it's probably relatively fast money to sell them for 10 to 15 £/€ per unit on Ebay or Amazon Marketplace.

Mauro Sans just measure the output voltage. The original one is always had stable voltage and had voltage tolerance +_ 1%

The plug he has from what I seen when traveling used in Slovakia and Czech republic

Actually Swiss have completely different. That is the French socket which is used also in Belgium, Poland, Czechia, and Slovakia so it is used by 133 million people. I think it also is used in Kongo. It is compatible width all modern European plugs that also work on Schuko. Essentially those are Neighbors of Germany and they did not want a German socket.

But what use is that when there is absolutely no mains isolation, except the lacquer on the wire? That transformer is a death trap, and the charger rightfully earns it's "super dodgy" rating.

@@TheSpotify95 of course, but it doesn't kill you first time you use it (or it is extremely rare), and also depending on what phone and phone case you have you won't really feel the leakage. It's also possible that you leave your phone charging and then go do something else. What the people who make these chargers want is money, they do not care about safety. They also do not care about how much they pay their employees for the work.

Yes, I also wonder how they can make the transformers like this and have a good sleep. They are probably hand made by very cheap uneducated workers (maybe seamstresses?) who just loosely follow some instructions and don't even know that electricity flow through those "strings". When I have to use my phone on a charger, I stay away from anything grounded. I use a good charger, but I do this subconsciously.

Maybe the high ESR of one of them is kind of damping the ringing... :)

@@DiodeGoneWild I think one of them is organic polymer and the other is aluminium electrolytic low ESR. They probably have different resonant frequencies. I really want to find out the real reason two different capacitors with close values are used.

They are different. One is organic polymer and the other is aluminium electrolytic low esr.
