Riello Plug Dialog 600 review

£38
Price when reviewed

The Riello is one of the most compact UPSs here, and weighing only 3.3kg it can be wall mounted. It ticks plenty of boxes too: the battery is user-replaceable, it has a USB port for PC control and RJ-45 sockets for modem protection.

Riello Plug Dialog 600 review

Like the Belkin, it boasts four UK-type sockets, three of which are battery and surge protected. But, where the Belkin can deal with 450W loads, the Riello handles only 335W.

There’s no reset button, but the power button and three LEDs are sensibly placed at the top of the unit, indicating battery faults and whether mains or battery power is being used. An alarm sounds when the power fails, doubling in frequency when the battery is about to expire.

The UPSmon 5 software has to be downloaded from Riello’s website. It’s easy to use, but doesn’t let you mute the alarm or check the battery’s charge level. There’s no USB cable bundled either: only an RJ-11 cable and a power cable.

After cutting power to the Riello, it lasted for 13mins 28secs – plenty of time to save work and shut down your PC. When subjected to our surge tests, the Riello failed at 6kV, meaning we couldn’t finish our testing. But the tests at 2kV and 4kV were passed easily.

While the Dialog 600 is the second cheapest here, the cheaper MGE offers more sockets, more power, longer runtime and software in the box.
