    Works as it should. Just follow the directions plug it up for a few hours before use. I haven't had an outage yet but I did test it by unplugging it and it ran everything well for a while.

    Excellent UPS for Short Term Backup

    This is the second unit like this that I have purchased. It has worked without fail during several power outages. I trust that this second unit will perform the same. If the beeping during is not desired, there is an easy way to disable it by just pressing the power button twice very quickly. You can turn on the beeper by doing the same thing again.
