I purchased a charger that plugs into the 12v volt powerpoint in my car for my P4 and it doesnt work. My car has 4 different powerpoints and none of them worked to charge the battery or the RC, with the key on or off, there looks to be an indicator light in the corner of the charger and it never came on nor did the lights on the battery or the RC. I confirmed the powerpoints worked with my cell phone, laptop and iPad mini. What next?

I'm sorry to hear you're having issues. Just to clarify, have you tried using the Phantom 4 car charger in a vehicle that has a slightly higher voltage output?
