The biggest difference is NAS and server integration, where the APC Back-UPS BX750MI scores 4/10 to the UPS ERA PLUS 800's 1/10.

APC Back-UPS BX750MI

APC Back-UPS BX750MI

5.2/10verdict: skip

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.

UPS ERA PLUS 800

3.9/10verdict: skip

The ERA PLUS 800 suits someone who wants basic battery backup for a small, simple load with UK plugs. It is not aimed at servers, workstations or anything with an active PFC power supply. Buyers who need automatic NAS shutdown should check the interface question before ordering.
