Griffin PowerJolt 40W Car Charger

Two long road trips in and my phone barely dropped below full the whole time, even with maps and music running. The dual ports came in clutch for charging my phone and tablet at once without any slowdown.

The 40W output is no joke—my laptop was actually gaining charge while I ran Google Maps and music at the same time. Plugged it into the lighter socket on a six-hour drive and never once saw the power drop below where it started.

The dual ports mean I can top up my phone and my wife's tablet at the same time on road trips, and it stays cool even after an hour of driving. Plugged it into the lighter socket and it fit snugly, no rattling.
