Many appreciate its surge protection and ease of use, finding it simple to set up and operate.

    This item works great. Very easy to use. Instructions are plain and easy to follow. We temporarily lost power but I wasn't trapped in my power recliner. It works as advertised.

    I have not tested it in an extended power failure yet. I bought it to handle small blips in power and it is doing great great for that purpose. Size is not bad. Outlets are well spaced to handle any plug I have. I was concerned because in the picture I thought that middle section was raised and that could cause some problems plugging in larger plugs. In reality, that middle section is a depression so it works well.

    This is a great little battery back up. I personally have four different power supply back ups, running various items in the house. We have multiple larger battery backups, running the PCs and monitors. We also have battery backups on the fiber, Internet as well.

    Solid, Basic Battery Backup

    Just wanted backup for the cable router/wifi... so when the power flickers I don't have to wait 5 minutes for XFinity to start back up. This fits the bill and is small enough/light enough to allow for different placement options while taking advantage of all the outlets. If you are looking for surge suppression over for the cable/coaxial itself, you'll need to step up to the next model. You'll need to charge it before using it... which is probably better for the environment and the battery life than having it charged before it left the factory.

    Honestly this was the best $50 I've spent in years. I currently work remotely in costa rica and the power goes out ALL the time. This little baby keeps my modem and therefore the internet up and running non-stop. Its a life saver.

    This backup battery/surge protector is perfect for my needs. My laptop has some backup protection. This device provides additional backup protection. This device also provides protection for surges in electricity which can occur during a rain storm. The CyberPower - 450VA was the perfect choice for my needs.
