We've seen (and tested) a fair share of interesting power packs during our time, and Exogear's hoping to make a mark of its own in this very juicy department with what the outfit's calling "the world's first" stackable battery pack. The newly minted Exovolt Plus consists of a main 5,200 mAh kit, which can then be paired -- or, in this particular case, stacked -- alongside a "Sub Battery" unit to create the ultimate portable charging station. One thing worth noting, though, is that each extra stack will be sold separately for nearly $50, while the essential Exovolt Plus is set to run at about $90 minus some change. Given its universal capabilities (30-pin, USB and micro-USB), something tells us the Exovolt Plus won't have trouble landing any suitors despite its somewhat hefty price tag. Still, you'll have to wait a little while before you can snag one of these, as it's currently listed as "coming soon," and its creator's yet to reveal when we can expect it to go on sale.
