APC Back-UPS BK350 350 VA 120 V | Standby, Desktop UPS

Keep small office and home-office equipment from dropping offline when utility power fails with APC Back-UPS 350 VA 210 W. This standby UPS is designed for light-duty protection where the goal is straightforward: preserve uptime long enough to avoid data loss, protect hardware, and complete a controlled shutdown. With 120 V input and output, it fits standard North American power environments and integrates cleanly into basic desktop deployments. The compact form factor makes it practical for workstations, modems, routers, and low-power network devices that do not require the higher capacity or management features of larger Smart-UPS systems. For organizations comparing price points, this model serves a clear purpose. It is not built for heavy server loads or extended runtime. It is built to cover essential equipment with dependable standby backup at a lower entry cost, making it a sensible choice for single-device protection, small network closets, and office endpoints where continuity matters more than advanced monitoring.
