CyberPower CyberPower CP550SLG/CP550HG Standby UPS 550VA 330W Compact

Muy bueno, no se habido la luz, así que no he podido probar su funcionabilidad como nobreak, pero los demás aparatos funcionan bien.

Works perfectly as backup for computer...

We have a small Haier thermoelectric wine cooler and use it to store a few "better" bottles we want to keep. The one problem it had was after even a brief power "flicker", the unit would go off and stay off. "Flickers" are fairly common in our rural area, so we were always afraid that we'd come back from a trip and find the cooler off and our effort to keep it at a constant temperature defeated. This week, following a severe thunderstorm, the power not only flickered, but remained off for an hour. The UPS unit kept the power on and the temperature steady for that time. Obviously it wouldn't last forever on battery, but we feel better that a brief outage will not affect it. I have not had the opportunity to test the other features of this model like computer shutdown and connectivity.

Excelente producto, la batería de respaldo duro 42 minutos conectado solamente con una míni Mac y minutor de 28 pulgadas Samsung

It arrived on time and in good working order. I plugged it in and waited 8 hours to fully charge the battery. Then I plugged everything I wanted to power with it. When I unplugged it everything I wanted to use the UPS for worked fine and when I downloaded the program to monitor the UPS with my computer it was easy to download and install.
