Hi there,
I have this third-party charger I use to keep an iPad charged while driving a truck. Bought it because if its low price (less than $10) and comes from a well-known brand, and I now just read it comes with a lifetime warranty). I got it after the original iPad charger died and Apple asked an unreasonable price for a replacement.
Even as I understand it's really not the most efficient way of converting power, I use it on a 120V true sine wave inverter (PWM-type) because I have too much USB devices to keep topped up while driving, along with the MacBook Pro. The second 12V socket also doesn't work.
However, I could notice the iPad responds erratically to touch when plugged to charger: the map moves around as if another finger was permanently laid on the screen. No issues whatsoever when plugged at home. As that inverter also includes a USB port for charging, I simply plug the iPad on it, but would still like to know what could be wrong with this setup, especially as the iPhones don't display such a behavior when using the inverter-120V charger-USB cable chain.
