All of the battery backup units ive ever seen are only good for computers IMO. The one i bought at costco that says "for HT/computer etc" only puts out about 100v when on battery, and its not much for a sine wave. Not suitable for amps, etc. IMO.
It also had AVR (automatic voltage regulation) which is pretty misleading. TRUE regulation means 115 or 120v at all times. this type of regulation means that it will kick onto battery mode if the power goes above say 130v or below 95. QUITE WORTHLESS! Of couse, the belkin unit could be different from the tripplite i have. But i doubt it
This is the one I have.
