R-i-g-h-t ... with absolutely nothing plugged into it maybe.

Fully loaded (865 watts) it might run for 5 minutes, half load maybe 15.

One way to find out how long it'll run is to power up everything you normally use, note the time on your watch|clock, and then simply unplug the UPS from the wall.
