    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.

    I had a recent power outage after this was purchased. It was connected to my Apple iMac and it prevented a loss of data. Data was saved and kept because I had the back up connected.

    We had a surge a few days after purchase and it clicked in as it is suppose to. Just remember is is designed to keep your devices powered until you can shut the device down properly.

    I always buy Cyberpower. This smaller unit was great for what I needed. I usually buy the larger VA but I needed a small one for the modem and router....Works great.

    This device replaced an older backup device. It has been working great and has good spacing for printer computer modem and router. Gives me enough backup time to save and shut down.

    Acts as a backup as described but has a loud beep and seems to drain a lot faster than you would think. hard to tell it is charged and has limits to current so it wont let you power a lot of things off of it.

    Light duty UPS from a good company

    Hard to review a UPS for at least a year, but my other CyberPower UPS's are impressive. This has a bit more power capacity and is noticeably lighter than the APCC unit it replaces. That was a pleasant surprise because it's easier to handle. Overall, CP's units are years ahead technology wise, IMHO, than APCC.

    Space saving design and gives me the power supply to cover the gap between loss of power to the time our generator kicks in.
