Q: My car charger barely charges anything

asked by on September 09, 2017

Whenever I plug a phone into my usb outlet to charge my car battery acts up. As for example one day I had my phone on speaker phone (didn’t have it plugged in) .. I seen my phone about to die and I plugged it in , maybe all of 5 minutes later I came to a red light, car is in idle, and all of a sudden my car start revving itself and the rpm started to raise as if I was revving the car and like it wanted to accelerate in a pushing back and forth motion. It was really scary so I turned my car off at the red light and turned it back on and unplugged my cord and it was back running normal again, but either my battery dies or something like that happens if I leave my charger plugged in long enough. And no one seems to know what’s wrong with it.

My car has 100300 miles.
My car has an automatic transmission.
