Charge your phone with power tools

For the weekend warriors with limited outlet access, a dying phone battery, and the animal instinct to check Instagram every five minutes, the PoweriSite is a pocket-sized device that attaches to all manner of cordless power tools, sucking energy from its battery into your USB charger.

You don't have to worry about dealing with a dead drill either, as typical high capacity power tool batteries hold eight times the capacity of an iPhone battery.
