There are some cases where you have to be away from charging stations. Being stuck with a brick of a phone or tablet makes us a little bit irritable, and if you’re going to be on the road, in the air, or out camping, you’re not exactly going to be near an outlet. This would normally be a great time to pull out a backup battery, but what happens if one just isn’t enough?

The Exovolt Plus could end up saving the day for your devices, and those of your friends, as it is the world’s first stack-able battery. The main unit will cost about $90, and each sub unit that will provide more power will be an additional $50. Every additional sub unit you add will give you more energy, and there isn’t a stated stopping point for how many units you can use at once. It will work with all sorts of devices as it has a 30-pin charger cable, as well as a micro-USB cable. This is a hefty amount of money to drop on backup batteries, but if this is an issue you often face, it may well be worth the money. No specific dates just yet, but is will be coming �soon�.
