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.

    We bought this to backup my sewing machine. Just the other day we had a power outage. My sewing machine did not even flicker. Gave me time to get to a point that I could shut it down properly.

    With so many power outages in the summer where I live, this is a must have for peace of mind. I have not lost any files due to power outages because of this battery.

    To get a battery backup surge protector for this price is a good deal. I previously had a different model from this company and it lasted a long time and I had no issues with that one.

    Plugs are spaced well. Note only one side has battery backup. The other side is only surge protector. No software to automatically shut down your system but you shouldn't expect that at this price.

    This battery backup has enough plugs for my computer, printer, and other peripherals, and will keep it running for about 30 mins during a power outage. Plenty of time to shutdown.

    Power went out about 10 minutes after plugging everything into this little champ. Power surged back on before I could shut down the computers. The computers didn't even notice.

    I love the battery backup on this product. I plug in my photo booth, printer, and accessories. If the power goes out, I have plenty of time to close out properly. Highly recommend.

    Just today we had a power surge in the office. Everything reset itself except what I was working on. No interruptions while equipment was plugged into this. Great purchase!

    Purchased back in Feb 2017, not problems since. Run as it should. Last power supplied had blown a few of its internal surge protectors and stop working. A very good upgrade.
