APC Back-UPS BX750MI

5.2/10verdict: good, not the best

The APC Back-UPS BX750MI is for people protecting a small NAS, router and switch who already own IEC C14 power leads. It suits a buyer who values line-interactive protection and decent battery runtime more than a pure sine wave output. It is less suited to anyone who needs confirmed automatic NAS shutdown or UK 13A sockets on the unit.

4.9/10verdict: skip

The SKE SK1500 is a 1500VA / 900W rated battery backup for buyers who want a lot of rated capacity and an LCD showing voltage and load. It suits someone protecting a small NAS, router and switch who will check the voltage and outlet details before buying. It is a weaker fit for anyone who needs confirmed USB shutdown signalling or a clearly stated pure sine output.
