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
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.
