    It provided the power to keep my phone's base station powered during a power outage. Cordless phones were able to connect to the base station, while the base station was connected to Xfinity.

    I use these with my location cause the brand we were using cost a lot more and got the same features and they were more fragile compared to the cyberpower battery. So for the price you can’t beat it.

    This thing is perfect for my work station as long as I don’t have my printer plugged into it. When the printer is plugged in it beeps (loudly) over and over every time you print. Apparently the surge of power is more than it prefers.

    Small, has plenty of outlets. The outlets are spaced far enough apart to accommodate most "wall wart" power supplies.
