RAVPower 24W USB Car Charger, $5 with code KINJA906

Aukey’s tiny USB car charger is a reader favorite, but this RAVPower model is the same size and puts out the same 4.8A of power over two ports, and it’s only $5 today with code KINJA906. Even if you have a perfectly good car charger already, it might be worth adding this one to your luggage for rental cars.
