    After bad storms effected the voltage coming into my building. Small devices could not keep consistent power. Most particular, my router. This saved my router bouncing at least 200 times in a week so very happy for what I got it for. Don’t think it has no more than 5-10 mins life in it. But cost effective.

    Connected this backup to our router/modem. Power has gone off twice in the last few weeks due to weather and fires. This guy was able to keep my connection to the rest of the world on and it kept me on one very very important zoom meeting.
