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.

    Decent for minimal protection. Hate that there is no software or cable to monitor UPS and automatically shutdown.

    For my set up I have a few block style plugs and since the outlets were space closely together I couldn’t get them all to fit.

    Couldn't find anywhere how long the battery worked for. Comes with a sticker on it that says only 35 minutes. Disappointing.

    Failed and deceptive internal battery size

    Within the first 6 months I realized that when we had a power interruption, the backup function on this UPS did not work at all. Yank the power plug and the devices plugged in to it immediately shut off. These were low power devices - just a router and a switch, not a computer. I kept it as a surge protector until it outright failed at approx 4 year of age. When I opened it to inspect the battery, I was shocked to see a tiny 3ah, 12V battery in a pocket designed for a much larger 4ah, 12V battery. Clearly, this was built to sell cheaply. Will never buy another like this from Cyberpower.

    I purchased this UPS based upon price and reviews. After two weeks I had a power surge/failure. The device powered down and protected my equipment, but never operated again. Returning to the store.

    I have purchased two WD backup drives, I will never purchase another as they both are not recognized any longer. Of course this happens 13 months after purchase, Do not waste your money.

    Returned it unopened after I felt that it was too light in weight (not having an internal battery to provide leveled power to electronics) and you were not able to open it to replace the battery.
