The Ewent Line Interactive UPS 600 VA With 6 Sockets is a lifesaver in case of a power outage. When this happens, the device gives an audio signal and an LED notification, and it also works as a kind of emergency generator. In case you have 120W of devices connected, you'll have about 10 minutes to store your files and properly close your devices. 3 of the 6 sockets are connected to the backup battery. This UPS also provides protection against overvoltage, short circuit, discharge, and overloading.
