    This UPS is smaller than the typical UPS of this capacity. I have it powering a WiFi extender in a closet; it fits well on a shelf.

    I live in a rural area. Some times storms will take trees down and there goes the electric. Generators are great but cost thousands. So this is great for short interruptions. Easy to set up.

    My PC would shut down on its own and I needed to try something to keep current flow regulated. My pc still shuts down but a lot less than before. I still need a electrician to check the current in my home office.
