    Needed a small UPS for my crockpot. When power flickers it would reset itself and ruin what I was cooking. This UPS fit the bill.

    I love this little Cyberpower battery backup. It powers my older desktop gaming computer and makes me feel very secure whenever my house has a surge or a dip in power. Very satisfied with the value for price aspect too.

    It did it's job right when our power went out recently. The router and security cameras where connected to independent batteries. Luckily the Internet provider was unaffected as well and we were able to see remotely what was happening although the batteries did not outlast the outage. Overall a good solution for short power outages.
