Maybe, but it doesn't really get hot and stays charged just fine when plugged into my car's 12v. I'm thinking it must be the adapter or USB cable not signaling to the phone that isn't a high-amp usb for some reason. Maybe got some water in it or something. EDIT: Finally figured out that it was a combination of the usb adapter and the usb plug going into the phone getting worked loose and creating a bad connection. Replaced the cable and is working fine now.

I used to run my phone's GPS app (with screen open) with it plugged into the charger via a USB dual plug adapter and it would keep the phone charged 100% no problem, but now it can't keep up and the phone will go dead over time even though it's charging. Not sure when it first happened but near the time I added heated grips. Does the FJ reduce the power output to the plug if heated grips are being used and taking more juice out of the system?
