You've got a desktop, a monitor, maybe a small NAS. The national chain says "six to eight business days." Your deadline is tonight. The BK650-AS puts 35 minutes of clean power behind your critical gear at 100 W – enough to save, close, and power down properly before the lights go. Three outlets are battery-backed; one is surge-only for the peripheral that doesn't need the full ride. It's a tower unit, not rack-mountable, so it lives on your desk or in the corner of the room. The lead-acid battery is user-replaceable (RBC17, compatible with BATT17-1209) – when it's time, you swap it yourself. No waiting for a technician. 45 dBA. 230 V input, IEC C14 in, three IEC C13 battery outlets plus one surge C13. The RJ45 phone/fax/DSL line protector is included. Straightforward protection for a single workstation or a small home-office setup that's been running on bare mains too long
