An uninterruptible power supply, or UPS (which is how we’ll refer to them from now on), are, at the most basic level, a big battery that kicks in when your power goes out. They range from really small units to enterprise units. We’re going to focus on testing smaller, desktop models that give you enough power for a desktop PC or NAS.

Our review unit will be Prolink Pro851SFCU 850VA.

If you want to monitor and control your UPS power input or output and manage auto-shutdown of the devices, I would recommend getting SFCU instead of SFC model.

The package comes with:

1x UPS
1x User guide book
1x USB cable
1x RJ11 cable
