The power dips, your screen flickers, and you're praying the save didn't miss. This APC Back-UPS ES 550VA sits on your desk and keeps critical gear running through short outages and voltage sags. Four Australian outlets get full battery-backed power; four more are surge-only for the printer or monitor that don't need a UPS. 230V in, 230V out. 1.83 m cable. Lead-acid battery you can swap yourself when it's due (replacement part: APCRBC110). Runs at 40 dBA – quiet enough to forget it's there until the lights go out and your machine doesn't
