    works great to keep your equipment on when power goes out or you have a power surge. Gives you enough time to shut things down if power is going to out for awhile.

    This works very well for me it keeps you from losing your data if you suddenly lose power by giving you time to shut down. It also protects from power surges.

    Backup battery works well as a day-to-day surge protector, and when needed has worked great for power blips, so that my wifi and computer don't restart.

    Due to the Covid-19 lockdowns, I had to start working from home. I was concerned about surges and outages so purchased this back up system. Sure enough, a storm knocked the power out at our house. I had time to back up all data that I was working on.

    A backup battery is a much needed equipment in any tech room or area. It doesn’t matter if you are not an IT person; this projects all your devices from sudden surges or power breaks.

    Purchased a new battery backup power surge protector. The one I had before lasted many years and wanted a new one of the same brand. Works well. I would highly recommend this product.
