    Our older back up went out with the last storm we had. This was an identical replacement. The previous one served us well, and I'm sure this one will also. It does what it's supposed to do.

    I use a battery backup surge protector for my desktop computer at home. Every few years the unit needs to be replaced when the battery will no longer hold a charge. I was delighted to see the price go down since the last time I bought one of these a few years back. I have used this brand in the past, with no problems.

    Got this to fix my parent's old UPS. This is a way to keep the internet up when everything goes down during a brownout or blip in power. Theirs went south and this fixed it.

    Replaces a dead battery on an old UPS. Hard to judge without a power outage, but it has the number of outlets needed and fits in the space desired.

    Simple plug and play device. This will handle a computer monitor and speakers for about 10 minutes to allow you to shut down and stop the brown outs that kill the computer boards.

    These work great. I’m glad to have them because my power goes out frequently. My only complaint is that no thought went into the layout of the plugins. So many items have power cubes and take up more than one outlet when plugged in as a result.

    of course, this review is based on how well we think it will work under duress in a real life situation. Power stays on if you unplug the UPS so it seems to work under test conditions.

    At 650va this will not run a computer for very long. However, I use these for routers, modems, etc and they can last 6-12 hours for this application. I recommend at least 1500va for computer applications.

    I have a number of these battery back up systems. They protect sensitive electronics from power surges and provide battery power to charge phones and keep lights on during power outages.
