The uninterruptible power supply (Ups) system provides surge protection for lightning-induced surges and other power events that can damage electronic equipment. This unit delivers enough battery backup to connected devices during a utility power failure so you can perform a graceful shutdown to protect against the loss of data and damage to valuable electronics, including computers, gaming consoles, and home networking equipment.The item has two Type A Usb charging ports with a 2.4A shared total output, which gives you a faster charging time and can be used while on battery backup power. The slim profile allows for discrete installation, and keyhole mounting slots allow for wall-mount applications as well.
