    It seems to be a very nice battery back-up, replacing an older model of the same brand which did its job for many many years.

    This is a quality product that has served me well ever since I bought it. The sockets are spaced out well to allow for multiple plugs.

    works great, using this to cover the gap between power failure and when the whole house generator comes on. Power backup is for networking equipment.

    Installed a Raspberry Pi on my parent’s home network to perform ad blocking. Needed an UPS to prevent the Pi from powering down in the event of a loss of power.

    Bought this when I ran out of power strips and I am not disappointed. It only powers my router and modem so if the power goes out at least I will have WiFi

    Bought along with a computer and drawing tablet for my daughter. Always good to have one. Costs more to replace equipment than purchase this.

    Im currently using it with my all in one desktop. It provides everything I need. Battery is not to big so don’t plug to many things to the battery side.

    The instructions were very simple. Let it charge overnight and then use. Time will tell if I made a good choice, depending on how long the backup battery lasts.

    purchased this to just run a computer off of. It can't take a ton on the battery side so just know how many VA you need and buy a little more than necessary.
