The Optimum OP-WFUSB is a WiFi smart plug timer and charger in one, with built-in USB Type-A and Type-C charging ports. The mains socket and the USB ports are controlled separately, so you can schedule an appliance while leaving charging available, or cut the charging overnight while the socket keeps running.
Useful anywhere you're short of sockets, such as a bedside, home office or kitchen counter, where you want one outlet doing the work of three.
