    It Does what its suppose to do. I needed a small Battery Backup to keep my Lan and Network NAS protected in case of spikes or Power Failures. This works great for me.

    i have my garage door opener plugged into this box in case of power outage. it was much cheaper than replacing the whole garage door opener with a newer one that had a backup battery.

    Needed a UPS to get us past short power outages. This unit fits the bill. Easy to set up, easy to use. Now have three for different devices around the house.

    Won't know if it works until the power fails. But did test it by pulling the power cord. No reason why it won't work. Great for the price. The small KVA model is all I needed to protect the water softener.

    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.

    I have this in place powering my network switch. I have a whole house generator and this is more than adequate to hold everything until it kicks in.

    Convenient in the event of brown outs or temporary blackouts. Will allow you to save your current work without loss. 20 - 30 minutes average life-- depending on whats plugged in.

    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.

    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.
