Customers are saying

Customers are positive about the 450VA Battery Back-Up System's long battery life, surge protection, and performance. Many also appreciate its affordable price, ease of use, and compact size, with several noting the convenient number of outlets. A small number of users mentioned a noticeable humming sound when the unit is running on battery power, and the lack of a USB connection was also cited as a drawback by a few customers.

    Purchased this for a work colleague and so far it's been running well. No issues, and seems to be able to handle the dual monitor set up.

    These work really and I have multiple. Batteries don't last forever 2-4 years but you can buy replacements fairly cheap

    They are much cheaper than APC and they do work well. With the cheaper price, you get a smaller battery that doesn't last very long.

    Handles fluctuations well. The small battery is enough to power my appliances for a few minutes.

    Bought this because my old ones fried when the current in my home went from 110 to 220 due to a faulty neutral in the circuit breaker box. This is perfect to keep my equipment safe and even running if this ever happens again as well as, lightning storms that occur here in South Florida.

    Probably overkill for our needs, but our BOSE radio fails to work for a couple weeks if the power is interrupted. All is good now.

    I have my "critical infrastructure" in my house running on battery backups. I dedicated this power strip to my cable modem so I can continue to have internet access when I lose power. It has ran once so far and kept the modem running for an hour, then power was restored.

    I needed a replacement UPS for an old one. I did not need anything large so this one fits the bill perfectly. The size is unobtrusive. I like the fact that the plugs point outward instead of at each other. I wish it had at least one plug to accept over size plugs without taking up 2 of them.
