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.
