    I needed 3 of these for my office. With all the rain that we've been having I feel better knowing I will now have time to shut off they computers.

    This unit is small but powerful. I was able to tuck it away so it is not easily seen.

    Good short term power backup

    When the storms come that knock trees into power lines, the electricity will frequently drop out for only seconds at a time. It wreaks havoc on fine electrical equipment. For a very reasonable price, this backup bridges the gap between the loss and restore of those brief outages. My particular use is for my UV water purifier for my well water. It prevents the early demise of an expensive UV bulb. The price of this backup is WELL WORTH not buying new UV bulbs all the time.

    Nice compact UPS for low demand situations. Using it to keep an Eero powered up so Wi-Fi network stays stable during blips on the grid or until generator kicks on.

    Cheap and does its job

    This is a cheap way to ensure you can safely shutdown your electronics if the power fails. They obviously won't power your electronics for long, especially a desktop computer, but it should allow you enough time to shut down should you lose power. I would not recommend this as a replacement for a UPS, however. I got this mostly to keep my network up and to use a surge protector. If you need something like a UPS, get a full blown UPS so it can send the shutdown signal to your devices, such as computers and NAS devices.

    Areogardens shuts down with brief power failures and require human intervention to restart. This backup has prevented a shutdowns, when I have been away from home keeping my plants from dying.

    Needed a small UPS to cover the power drop between outage and the generator coming online. Also the smaller size made mounting it easy.

    I bought this item when recently a cheaper power surge protector's alarm went off. Freaked me out. Got this for my cable, TV, modem and router as well as PC & monitor. And so far, no issues. LOVE IT!

    Easy set up. Haven't had a power outage yet but I ran a quick test and it worked as advertised. There are longer lasting solutions but this works for me at the price point.
