The CyberPower SL750U 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 SL750U has two Type-A USB charging ports with 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.
