Almost every mobile electronic device comes with its own wall outlet-to-USB box, be it Apple’s cube or any other manufacturer’s transformer. But let’s face it: you lose the things more often than you misplace your house keys. With the SnapPower, you can easily add a powered USB plug to any of your home’s outlets without having to rewire a thing. Simply unscrew your current cover plate on an existing outlet, and screw the SnapPower instead. Special prongs on the inside will make contact with the wiring screws on either side of the outlet, giving that USB port 1A of juice. The two other receptacles will keep working normally, so it’s all sort of seamless. Considering it’s $14 a pop, it’s feasible to imagine retrofitting your entire home with these at a reasonable cost.
