    For the money, this seems to be one of the best home battery backups you can buy. No problems installing it following the recommended charging time.

    It's pretty cut and dry. It works like a champ. I would prefer more battery-powered sockets and less surge-only ones, but it works as advertised.

    Use this to supply my wifi router and modem. means i have a few hours of wifi even if we lose power, for not much more than a standard surge protector.

    Make sure you understand the times it says it can power all your devices that you typically use. For my iPhone and laptop it lasted about a half hour, when buying it I saw 6 hours and didn’t see the little wrong that states itll last that long when connected to a router/modem and that’s it. I was going to use it as an extra power source for a enclosed area on the back porch but now it’s just a glorified, way overpriced surge protector.

    I've used this brand and APC many times and they are both very good battery backups. The only reason I lean toward these is that APC disconnects the battery, which is good, but it's a real pain in the buns to reconnect it.

    I bought the CyberPower - 650VA Back-up System for my wife. Ihad just bought her a new $17,000 quilting machine. One of the owners of the store was installing it and said, you better have a good battery back up for this machine because if you had a power outage, even if you have a generator, because it can ruin the computer inside the machine. The CyberPower was the highest rated online and at a great price.

    Good battery back up. I had to purchase 10 of these at different locations, 2 of them were not working at all,I had to return/exchange them. Overall performance is OK, I would have to keep an eye on them to make sure they are stable.
