I have a 2010 Chevy Equinox LT (2.4L / 4 cyl). Recently I bought this dashcam. When I plugged the charger into my 12v cigarette lighter port in the front of my car, plugged the usb in, connected to my dashcam and turned it on a few minutes after working it turned off. I later found that ALL 3 12v charging ports in the car were dead. I could not even charge my phone anymore.
After taking my car to the mechanic I found the fuses were blown. After replacing the fuses, I was able to charge my phone and everything was working great. I plugged in my dashcam and it worked for about 2 hours before all my ports went dead again meaning my new fuses were reblown.
I want to test out the charging unit and usb cable to make sure they're not defective and causing a short. I have attached a picture of the charging unit and usb cable below.
If the cables are fine, what are my options for using this dashcam in my car?
