I've been wondering why my cheap USB car charger wouldn't charge my iPhone. Time to add a few resistors!


Read like link bait. Please change the title. Battery charging is not in the realm of secrets and mysteries.


In this case it is, since Apple devices don't charge from USB in the regular way.


Isn't that more a clever technique than a mystery?


Yeah I guess.

Another lesson learned: AA batteries are good.
