    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!

    I love these things. I have one for each of my computers as well as one on my on-demand hot water heater. These things are great during a power outage and have really saved me quite a bit of hassle with short power outages. The only downfall, for me at least, is that they only last 3-4 years at most.

    I did need the power of a larger UPS. Just something capable of keeping my modem and router up. This fit the bill perfectly.

    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.

    Living in Florida it was important to have a battery back up. I had my previous one for seven years and it was about time to get a new one and this one really fit the bill

    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.

    This Battery Backup/Surge Protector is just big enough But small enough to put it out of sight for my needs.

    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.
