APC Back-UPS ES BE550G 550 VA 120 V | Desktop UPS, Battery Backup

Keep critical desktop equipment online when utility power drops or sags. The APC Back-UPS ES BE550G provides 550 VA of standby protection in a compact form factor built for workstations, small routers, modems, and point-of-sale peripherals. With eight outlets, it gives you enough connection points to separate battery-backed devices from surge-only loads, helping preserve runtime for the systems that matter most. This unit is designed for straightforward deployment at the desk or under a counter, where space is limited and uptime still matters. Its 120 V input and output make it a practical fit for standard North American environments, while the Back-UPS platform is known for protecting against the everyday power events that can interrupt work, corrupt data, or force unnecessary reboots. For smaller environments, the value is in precision: enough capacity to ride through short outages, enough outlets to organize connected gear, and a footprint that does not demand a rack or dedicated power room. It is a sensible choice when you need dependable backup power for essential electronics without stepping up to a larger, more complex UPS class.
