Being a "UPS" doesn't affect the unit's surge protection. Surge capabilities will be separate from the UPS capability. Those that use a UPS tend to do so to insure the power remains uninterrupted, usually to keep Server's and projector's from shutting down. In theory, it gives the owner time to turn off the equipment to allow for a "normal" shutdown (i.e. power down the lamps in a PJ, and some UPS's can do this for you, which is great if you're not home when it happens). Obviously also helpful if the power outages are short. If you are in an area prone to Brown outs, etc., and the equipment requires timed shutdowns, then a UPS has value. Surge protection is the other side of the UPS capabilities, and that is specific to the qualities associated with the component (and for that I prefer Torus).
