A UPS has two ratings and the lower one is the limit. This unit is rated 700 VA and 400 W, so the equipment plugged into its battery outlets should draw no more than about 320 W if you want the usual 20% headroom. How to size a UPS.
Its weighted efficiency of 98.7% compares with a median of 98.6% across 99 certified units within 25% of its capacity. With nothing plugged in it still draws 3.0 W, about $3.41 a year at 13¢/kWh just to stand ready.
