About this item
Power cuts and brownouts can wipe out unsaved work, and the Eaton 5S550 UPS is a line-interactive desktop tower battery backup, listed new at $94.99, that sits between the wall and a home or small office PC. A UPS gives you time to save files and shut down safely, while line-interactive designs smooth out common voltage dips without switching to battery every time.
Is the Eaton 5S550 UPS big enough for my setup?
Add up the wattage of your computer, monitor and router, then compare it with the rated capacity in the listing.
- Capacity: the 550 in the model suggests its VA class; confirm both VA and watt ratings.
- Outlets: check how many are battery-backed versus surge-only.
- Plug type: confirm it matches your region.
- Battery: look for runtime figures and replacement battery information.
