Multi-Function USB Outlet: Wall-mount design for duplex outlets; just plug in to use, fitting a duplex outlet perfectly. The center screw secures the unit to the wall, using the screw at the middle to secure it onto the wall for a duplex outlet, so it is not pulled out when pulling the plugged-in devices and helps prevent loss of power. You get a 5 AC outlet splitter (3 sides) with wide space in between and 4 USB charger ports. This unit works only with duplex outlets and Duplex Receptacle Outlets; other outlet types, such as GFCI outlets, cannot be secured to the wall. The back groove design allows the unit to sit flush against the wall. It is suitable for Duplex Receptacle Outlets and wall outlets with more than 1 inch of space between sockets. It cannot be used with outlets that have more than 2 sets of parallel sockets. Five AC outlets feature 2.1 inches of spacing, larger than a standard 1.5 -inch socket, making it easier to connect various types of equipment. Four USB charging ports include USB-A ports with 5V/ 2.4A Max output and a USB-C port with 5V/3A MAX output.
Built-in smart technology detects charging devices and automatically delivers an optimal charging speed, compatible with Kindle and most USB devices. The USB-C port is not Quick Charger 3.0 and does not support devices requiring 9~22V charging voltage. The 2-level complementary surge protection circuit uses TVS and MOV (metal oxide varistor) components and provides a minimum 1680J energy-absorbing capacity
