    hate that it beeps when battery use is active. but it does do its dudiligence. I have my work computer and monitors and internet plug in at all times with the battery portion. the other four side is regular electric. so zoom into picture and you'll see that only 4 ports dedicated to battery which is okay for me. but for others who needs more don't think its all 8. also drains fast. but i didn't expect much from a cheaper brand apc. this is exactly what i need it for. not for longevity.

    Replaced five year old same model that finally died. It was cheaper to buy new than to go to the bother of finding a replacement battery.

    Bought this to allow my 90 year old mother to lower herself out of her power recliner in the event of a power failure. Has already used it twice and worked like a charm.
