Customers are saying

Customers frequently mention the 750VA Battery Back-Up System's great size, reliable battery life, and overall performance. Users appreciate its ease of use, excellent value, space-saving design, and adequate surge protection with plenty of outlets. While some find the plug spacing a bit close and the unit somewhat heavy, the noise level is generally acceptable. Overall, the positive aspects of the product appear to outweigh the minor drawbacks.

    Great for my laptop

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    I bought this to use as a power source for my older laptop with the battery removed. Replacement batteries for it have become hard to find, and continuous recharging wears them out prematurely. This allows me to remove the battery and use the laptop without losing data, or corrupting the operating system in the event of a power failure. The power panel software will shut down a computer safely when electric service is interrupted.

    Great Little UPS for the Price

    Needed something in a hurry with a storm approaching and power outage threats. Not something huge but not something that was going to carry a big price tag either. This fit the bill. I like that it gives a reasonable amount of power for a computer or several small devices to protect them but it's small footprint makes it easy to move around and to conceal as well.
