    Great back up battery for when power goes out plug in the router to it and it also acts like a power surge bar. Perfect for things smart home and backup duration options are up to you and what you buy.

    Great little device, but not the one I'd recommend for a PC. I bought this one, heard beeping noises whenever I pulled up adobe Premiere to edit a video, and found out it was because my PC was drawing more power than this could protect. Turned it in for it's bigger sibling, the 900w version.

    This is a nice UPS for backing up a computer desktop - plenty of outlets, and (depending upon what you have plugged in), plenty of time to do a proper shutdown when the power fails.

    Excellent power back-up and protection. I used this as a battery backup for my home internet and Ooma phone. Never lose signal strength as long as the tower has power.

    I just needed a new battery back up to keep my router and modem on during short power outages. I got to test it a few days ago while a new smart meter was being installed at my home. My router and modem stayed on the entire time without needing to be re-started. I'm not sure how long it will last during a prolonged outage and hope I don't have to find out.

    Originally bought for my gaming PC and peripherals, but it was a little underpowered for the load. Bought an APC 1500va to handle that, and moved this UPS to my entertainment area for TV, Apple TV, etc. This performs perfectly for that scenario, and very happy to have all of my important electronics backed up and safe w the two UPS units.

    Item works well, has enough plugs for all my computer accessories. Fits well in a corner of my desk so I dont have to reach under to add or take items away.

    Well, it's a UPS with battery backup, and as far as I can tell it's doing its job, I haven't had any issues so far, and I think I've owned it for about a month now. The product is quite a bit lighter than my previous unit, which is a plus to me. It's also good that it has two USB ports to charge your devices, my older one didn't have that. Based on my experience, I guess I'd recommend this product to others, it wasn't too expensive, and if it protects your computer and gives you a bit of time to shut things down in the event of a power outage, I'd say it's a good purchase, basically a cheap way to insure your equipment.

    This has saved my computer twice now from sudden hits to power. We live in a new construction area with periodic stoppages in power. Electric drops can be one of the worst things to happen on a computer. I feel much safer plugged into this.

    It is exactly as advertised. Easy plug and play setup, no complications in setting up. It is a bit heavier, but it is expected when dealing with back up battery systems.

    It is very useful to have, especially if you have a computer or some other devices you do not want to get damaged due to power outages. When the power goes it does remain on but I cannot say for how long for sure as it usually comes back after maybe 10 minutes. It is great to have though

    Bought two of these because, as a remote worker, I need my computer to not shut off abruptly when storms are in the area. I have one for my work computer (bedroom) and one for the internet/wifi (living room). So far so good.
