hahaha. I had the same problem! Driving with my phone as my GPS plugged into my car charger it would DRAIN! WTF? Installed gSam Battery Monitor: Phone is drawing 462ma from battery during GPS use, charger is providing 100ma?! lol
I e-mailed DX and they said it must be the charger, not the cable, so I ordered one of their dual 2.1 amp ones. Worked slightly better but none of my radio stations worked while my phone was charging and two weeks later I get into my car and smell nothing but electronic burning smell. Charger was melted right inside the 12v socket, couldn't be removed, had to replace the socket. Can't believe it didn't burn my car down
