World’s first stackable battery powers your iDevices when you’re away from the mains

Stuff like a power outage, a long flight and a weekend excursions are some of the many reasons why we may require an alternate power source. Whatever said and done, powering our iDevices is one of the most important jobs in the world and Exovolt Plus is a tool that will do exactly that for us. So, a unit such as this would certainly play a good ‘emergency battery’ to us.

The main power has a capacity of 5,200 mAh and an equally hefty price of $90, while the sub batteries are $50 a piece. We don’t know the capacity for the sub batteries, but considering the price, it should be slightly lesser than the main. The battery comes with a 30-pin adaptor, a USB and micro-USB connector, so it can be used for several devices.
