When plugged into the DC port (cigarette lighter) of a car it can provide enough juice to power up smartphones, GPS devices, cameras – even a laptop – all at the same time. A small, almost completely silent, fan keeps the interior from overheating so that it can continue pumping out the power indefinitely, making this an essential piece of gear on any driving excursion.

That's enough to provide each of the USB ports with up to 2.1 amps, which is sufficient juice to charge a tablet including the notoriously power hungry iPad.

Still, the inverter is efficient enough to keep multiple devices up and running for when you need them.
