The USB port is so ubiquitous, we need it for just about anything these days. Charging our devices would be its most useful function. So how do you add a USB outlet on your wall without requiring any wiring?

This is the SnapPower Charger. It replaces the cover plate of your wall socket and features a pair of metal prongs that make contact with the screws holding its electrical wiring in place.

When snapped and screwed into place, the USB port can instantly power your devices.

The folks who make this are on Kickstarter now, so go ahead and support them if you like. You can even pre-order one too.
