Yes, but what if I already have a charger and I don't know where it came from?

  It is probably hard to say, from the outside they often look legit. I have seen one once, but it became more apparent when we compared it to a genuine charger (usually the print is off in some way). Since counterfeit chargers typically have fewer components, apparently weighting the charger can also help finding counterfeits: https://www.electricalsafetyfirst.org.uk/blog/how-to-spot-a-fake-apple-charger/ https://www.electricalsafetyfirst.org.uk/blog/how-to-spot-a-... Of course, it's probably not beyond them to add some weight to make you believe it is real. I guess if you have the right tools, you could also measure output quality.

    They do add weight (and go through the trouble of implementing ring structures to fake writes) https://youtu.be/g8ovFkd8myE https://youtu.be/g8ovFkd8myE

  Anecdata: My A1265 charger weighs 23g and my A1385 weighs 25g. This article shows how to tell between an authentic A1265 and at least one fake one: https://www.righto.com/2012/10/a-dozen-usb-chargers-in-lab-apple-is.html https://www.righto.com/2012/10/a-dozen-usb-chargers-in-lab-a...

  In my limited experience, counterfeit iPhone chargers do not have a serial number printed inside the USB connector. Real ones do have it. I've found this picture that shows they've started printing a "serial number" on the fake ones too https://apple.stackexchange.com/questions/243541/how-to-differentiate-original-and-fake-apple-5w-usb-eu-power-adapter-a1400-md8 https://apple.stackexchange.com/questions/243541/how-to-diff...
