Car Power Inverter - 130W DC 12V-AC 110V With USB 5V/50Hz-DC 5V/500mA
Have it worked well for a 15-day drive in my month-long trip. A bit noisy when when the fan turns on to cool itself down. And it's not a universal outlet, only worked for those two pin plug-ins. I tried to connect a three pin charger but failed.
