    a good size for a small-medium powered computer

    Does not have USB monitoring which is fine, it can keep a small-medium sized computer running for a couple minutes on full battery charge. Not sure if it can be silenced when power goes out. That is a minor thing, although I am sure someone will know the power is out when things do not turn on, the beep is just a reminder!

    Bought this for an elderly parent who uses an electric lift chair. If the building loses power, the lift chair will still function allowing our loved one to lower the chair and not get stuck in a laid back position. We have not had opportunity to use this device.

    This ups is cheaper than the APC, and is rated the same to similar units, but it has a small battery. Works good.

    What can i really say about this item? A ups is a UPS, i needed a new UPS to replace the old one i had. This has the same number of surge and battery backup outlets as the one before. The old one served me well for three plus years and i expect this one to do so as well.

    Easy to unpackaged and quickly had the old one replaced and new one doing the obligatory pre-charge of battery. The unit seems to be working effortlessly.

    I have a piece of electrical equipment that I have to move around the house occasionally, and everytime I unplug it and then plug it back in I get an error message. Now I plug it into this battery back-up, so when I move it, it stays powered up. Works like a charm.

    Basically to sum this item up, it is a fancy plug strip that has the amazing ability to power your devices long enough to power them down safely should the power go out and I love it!

    This device works as advertised. One word of caution would be, the limitations on voltage. I have a portable AC unit plugged in, lamp and router. On a somewhat regular basis, it will triple breaker on the device, needing a reset. Beyond that, though, I am very satisfied.
