Some good electrical outlets with built-in USB ports are the Newer Technology Power2U AC/USB Outlet and the Leviton USB Charger Outlet, according to Remodelista. Both of these electrical outlets have the ability to charge two USB devices and two devices with electrical prongs.
The outlet from Newer Technology features smart circuitry that only gives each USB device the power it requires. The outlet also features spring-loaded shutters that help eliminate electricity being sucked out while not in use. The Leviton model comes in 15- or 20-amp varieties and 3.6 amps of charging power. Without the need for USB adapters, the outlet provides a clean, aesthetically pleasing space on a countertop.
