Yes, if the model lists a UPS or EPS mode. The station sits between the wall and your devices, passes wall power through, and switches to its battery when the grid drops. The figure to compare is the stated switchover time in milliseconds.

What pass-through means

While wall power is present, the station feeds your devices and recharges itself at the same time. Your load counts against the station's AC output rating in both states, so check it against the continuous watts in the comparison tables. Our sizing guide shows how to add up a load.

Which loads tolerate the gap

Desktop PCs and NAS boxes depend on their power supply's hold-up time, which few makers publish, so check your PC or NAS maker's documentation before relying on a station as its UPS.

Keeping a station on wall power around the clock is a battery-chemistry question too; see LiFePO4 vs NMC.
