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.

    I bought this backup power supply to maintain memory/clock in a device that is older and won't do so during a power failure. Works perfectly. the instructions gave good info on what it does and when but the setup was too simple to really need instruction. Plug it in, charge overnight and then use it.

    I was looking for a replacement battery back up for one with a replaceable battery. I bought this one that is about half the cost of one with a replaceable battery. When tested, it has enough run time to power down during a prolonged outage. will definitely buy again to replace others as they age out.

    worked well on computer. prevented spikes as well as could be determined. Wasted about 15 minutes when power went out. enough time to close out valuable programs. also tried on DVR to attempt to even out spikes a keep it from rebooting. Jury still out on that one.
