Designed to replace any standard outlet, this tamper-resistant receptacle features a 15-amp outlet as well as two built-in USB ports that allow users to charge multiple 5-volt DC electronic devices. It eliminates the need for bulky transformer-style plugs, can potentially reduce energy costs, and is no larger than a standard combination device. Cost: $23. Legrand. 877-295-3472. www.legrand.us.
