Dark Energy Reservoir

Readers of this site, being aficionados of fine technology, are likely no strangers to running out of charge when they need it most. Until battery tech improves such that it only takes one charge to power a smartphone for a week, most of us will need a backup plan at some point.

Enter the Dark Energy Reservoir. This portable, rechargeable unit can hold enough energy to power a typical smartphone for a week, but is small enough to easily fit into a bag or maybe even a pants pocket. Any device that can plug in via USB is compatible with the Reservoir, so we’re talking iPhones, iPads, cameras of all sorts, and more.

A single Reservoir is $129, while a double pack is $249. They are available in black or white.
