    Yes it's big and pricey. Considering what it cost compared to what it saved makes it easier to justify. This is my second unit and it's saved a laptop, desk light and those "fruit brand" chargers. Anyone else WFH should consider putting it on the must have list.

    Actually use it in a band where we use computer system to play back tracks and in most venues, the electrical is poor and bogged down with many other appliances. This causes brown outs and spikes which we encountered a few times during performances UNTIL we started using this unit. IT WORKS! Buy it!

    Bought this for my home game server and it's pretty good I wanted something that would keep my computer from losing power just long enough for the generator to kick on

    We already have one of these on my husbands computer. We recently purchased a large fish tank and lost our first batch of fish due to a power outage. We bought one of these for the tank and it saved our fish during the next outage. (We have had a few issues with power surges since Hurricane Florence)

    Just what I need for my router to keep it working whenever the power goes out. It also serves as a power conditioner when HECO power spikes and sags throughout the day when my house lights flicker.

    Had one of these units before. Replaced the previous one since it was like 10 years old. Very important to have a battery back up so your computer and stays on even though the power is cut off. Then you can take the time to shut down your computer properly

    We are counting on this to prevent power outages for our technology. Living in a rural area, we have many short blips that can be annoying.

    We purchased this battery backup for the overhead kitchen cabinet lights. I was constantly having to reset the timers when the power flickered off. This far in the country it is a constant issue. The nice thing is that now we have light in the kitchen area even without power!!
