    So far this has proven to be an excellent UPS. I use it to support my cable box which was having problems with short power interruptions causing it to reboot. Problem solved. It includes two USP power plugs which I use for my Fire-Stick. I I can also sleep better at night knowing that all my AV equipment is protected against power line spikes. All this for less than $ 50
