    Works when the power goes out. I wish the noise volume was configurable, it is a very loud beep.

    We haven't had a power outage or surge yet, so I don't know if the battery part works or not, but power flows through it....

    Missing a key very important feature

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    This may be an ok ups but it is missing the really important feature ... a USB port. Without a USB port you can’t really use this with a computer to shutdown properly in case of a power failure. If you need this for your router or some other equipment Ok but for a pc or Mac it doesn’t cut it.

    No, I would not recommend this to a friend

    We use these at my job and I must say this thing comes in handy during the power outages. I bought one for the house when the power goes out for a few mins. Everything stays on with the about 10 min backup battery.
