We do a lot of things in the name of convenience. It’s normally a balance of time versus money, and which one of the two is the lesser evil to give in to. When it comes to keeping your phone charged, you don’t mind spending a bit on a backup battery, but what about your tablet?

The Just Mobile Gum Max Duo is a backup battery that will take care of your phone and tablet simultaneously. It has a 11200mAh capacity, and is equipped with two USB ports. While it was ‘meant’ for an iPad and iPhone, that doesn’t mean it won’t work for other devices as well. You’ll be able to see how much juice it has left thanks to its 8 LED indicators. This battery pack alone will cost you around $130, but tacking on another $13 will get you a fancy rubber sleeve that will…make it look prettier. This has no other purpose. All in all, it’s a backup battery, and if you don’t have one, but have lots of devices, it could be of use.
