There are a lot of portable backup chargers out there. Like, a lot a lot. But the new Mophie Powerstation Plus is the one you should be relying on to refuel your ailing devices. Here's why: About the size of a pack of Dentyne, the brushed aluminum box looks less like a piece of tech and more like a companion piece to your money clip. And it's smart, too, with fold-out charging cables tucked inside (available in either Micro USB or Lightning), a refuel rate twice as fast as a standard charge cord, and, the ability to know — and dole out — the correct amount of power each device needs. It's available in four different capacities, from a 3,000 mAH version that will revive your smartphone twice, to a 12,000mAH one good for eight refuels; all of them still manage to stay slim enough to fit in your breast pocket.

With quick charging times and clever embedded charging cables, the Mophie PowerStation Plus is the backup battery that belongs in your briefcase.
