All your valuable electronic devices have a USB power cable requirement. Then why not have a USB wall plug too?
The SnapPower charger replaces the outlet cover and adds a USB port below the standard power outlets.
That means there’s no wiring involved — in fact, the only tool you need is a basic flat head screwdriver. Unscrew the existing outlet cover, pop on the SnapPower, tighten the screw, and you’re done. (You should also turn off power to the outlet from your breaker box while you do this for safety precautions.) The whole process takes less than five minutes.
