Luckily there's a protocol between the charger and device for negotiating the supported charging parameters, the newer chargers are not going to blindly push up the voltage to the high limit
I would guess that the vast majority of chargers out there do not follow the USB standard. iDevices are so prevalent that you've often got to check any 3rd party battery/charger supports "Android" which is usually code for not using iDevice style voltage sensing on the middle pins.
