Like the apple one, still a crap charger by any standards just look at the SAMXON caps! Bound to fail!
That thing just terrifies me, well, it costs 30$

Neither of the chargers in the video was an Apple charger. Both were fakes and neither cost anything near $30.

You can see if you follow the link in the description that the genuine iPhone charger has a different and very sophisticated design with many clever features.
I was looking at the teardown of the real one. That one has a badcap right where it matters the most, output!

Here is a link to a very detailed tear down that I found on the web.
This is genuine Apple power supply that is dissected.

Unfortunately as long as there is demand for low cost consumer goods their will always be someone to fill it. Between lead in paint on children’s toy’s, poisoned pet food unsafe electronics….

People need to educate themselves if it sounds too good to be true it probably is.

From that you can say there is certainly coming a lot of dangerous crap from China, and it is not harmless.

From that?

So you have surmised that it only cheap & nasty Chinese product that causes fire from that? I call flawed assumption!

Where is your evidence that all these faulty plug-packs etc, are of Chinese origin? How do you support your inference that Chinese manufacture equals cheap & nasty. You prime source of statistics being some "Local Newspaper", authoritative stuff that! Why not switch on some tabloid television too, they run this kind of crap at least monthly. Who needs standards and test labs when we have cadet journalists right?

You need to think back to this quote from Monty Python which demonstrates the absence of wisdom in your wild assumptions.
"Fish live in the sea!" "Carp are fish!" "Therefore all fish are carp!"

Sure there is a lot of rubbish coming out of China, as well as some quality product. This is a fact which prevails throughout most of Asia. Once again you are putting Xenophobia before fact or reason!

"Made in China" does not instantly signify quality nor does it automatically equal death-trap. Lets face it if you were to solely rely on product from your own land, the technical pinnacle for most, would be the Austin Allegro and the open wire kettle. Safety plus, indeed!

Hi Dave

Thanks for the video, it was entertaining but like many other viewers I wish you had shown a true side by side comparison with Scopes/Load/Multimeter etc. of the Cheapo vs the real thing.


If you are going to do a new video let me just add a few suggestions that will make it even more useful.

Have a real one on Hand |O

And here is something you might want to let the viewers know:

If a person wants to know if they have a real one versus a knock off I know a few methods that anyone can try. I will list them from the least reliable to the Most.

1) The Label Info

2) The Balancing trick, the real one can stand up on its plug connectors with ease when put on a level table.   The Fake ones are almost impossible to make them stand up. Sometimes it can be done but it takes many tries, while the real Apple ones do it on almost the first try every time.

3) The Weight:  A real charger weighs 23.07 Grams and the Fake ones vary all over the place.  I have one of the Cheapos that is exactly the same one you used in the video marked “made by Apple”, it weighs 19.56 Grams.   If you don't have access to a precision scale just pop by your local Pharmacy or Jewelry Store and explain that your trying to find out if you bought a real one or Fake and they will almost certainly weigh it for you.

4) Connect it to a scope and the real one has almost no ripple or noise, the fake has a nice big layer of noise.

5) Connect a Load and the real one will go up to 1100ma and maintain aprox 5V but the fake ones tend to drop off between 300ma and 500ma of load depending on the AC supply.  At 110V they only go up to 300-400ma and 220V gets you 450ma to 600ma before the voltage starts to plunge.

Those are the five best tests to know the real from fake (apart from opening and ruining the unit).

For people who don't have any electronics background or equipment the best test is number 3.  Almost all the fakes vary from Apples standard 23g weight and it's pretty easy to get it measured precisely.

Looks like i got one the worst ones! It weighs 30 grams  :-DD I don't even need to plug it into a scope, my portable speaker tells the whole story!
Oh, the 30g one i got can actually charge my phone  :o

I give you : the blown up ones!

Uncle Vernon:
Of course, not every single thing made in China is crap. Nobody is retarded enough to claim that. But spare me the PC jingo. China specializes in cheap imitations. EU import statistics prove this. They even have their own term for it: Shanzhai.

Wasn't that what I had stated previously?

Oh, I wouldn't be too sure about that.

You could spare yourself lots of bother by obtaining a clue.

China produces, what its market demands, it has beaten the world in terms of low cost manufacture.

Well bully for the EU. While they've been busy creating mountains of useless statistics, pointless legislation and meaningless standards, China and India and most of Asia has been busy actually making and selling stuff!  With both the genuine item and the imitations originating in China, anyone using country of origin as a determinant of quality is making themselves look like a rank tool.

Yah meaningless standards about poisonous chemicals and electrical safety regulations. Who needs their health anyway right.  ::)

Sometimes, Chinese stuff is so bad, the problem isn't that it functions poorly, it's that it doesn't stand a hope of working. I call these deliberate deceptions "pretend products".

I don't care if keep your head up yer arse, but if anything makes you look like a tool, it's your personal attacks.

Some Chinese stuff isn't and some Chinese stuff is of serviceable quality. You may be slow on the uptake, so I repeat again for your benefit. Country of Origin is not the sole determinant of quality or usability!

Quote

That's good, but you need to realise how much I care about, what you care about! Nof do I care about the personal insults or profanities you believe necessary to bolster your lack of reasoned or rational thought.

Quote

You're the one making the insults persomal. (see above) But if the shoe fits, and you can identify yourself within a generalised criticism then that's your issue.  I cannot help it if you choose to be thick!   8)

Not sure, but if many of you think that bashing certain country, because they're producing dodgy stuff is unique and new, trust me, nothing new about this at all.


Just ask your parent or grand parents, this kind of bashing has been for ages ....


60's - Damn Japanese clone, why we still buying this shitty stuff, next time buy anything made in German .....

70's - Step over my dead body 1st before you bring those "Made in Hongkong" shit in here.....

80's - Why these days we almost bumped into these shit labelled "Made in Taiwan" or "Korea" almost every where ? ....

90's - Just couldn't stand it anymore, I want a native English staff for this telephone support call , not someone lives thousand miles away speaking English with "Indian" accent clown, anyway, these clowns are robbing "our" IT people's job as well.

2000's - ..as seen in familiar video blog  ;)  "made in German"... <two thumbs up> .......what ? made in China .... ... <thumb down> .... "damn chinese " .........  :-DD

When something good comes out of China, I say so. And lots of good stuff comes out of China. Every product gets judged on it's merits.
The reason I harp on about China a lot is because it's boring. I don't want everything in the world to be made in China. I want other countries to keep their manufacturing capability too. Which is why I get as much of my uCurrent made here or outside of China, and get a nice little feeling when I see something that's not made in China.
