A nifty device during blackouts

If you run your network-attached storage, or NAS, round the clock, or fear losing your work on your PC if there is a blackout, this is one device you can consider.

It combines an automated voltage regulator, or AVR, with a large back-up battery.

This uninterruptible power supply, or UPS, provides five to 30 minutes of power - enough juice to save your work and shut down your PC, game console and other equipment the correct way in the event of a power failure.

It is really easy to set up. At the back of the device is a trio of three-pin power sockets. Two of them are connected to the built-in 1,000VA battery, so that your devices continue to run on battery when there is an outage. The third is a bypass socket meant for connection only to your non-critical devices since it is not connected to the battery. I connected my PC directly to one of the two sockets. My multi-adaptor with five or six connected devices was connected to the other.

My PC, router, printer, monitor, 32-inch TV set, Playstation 4 console and mobile phone were connected to the UPS device.

To simulate a power outage, I unplugged the device's power from the mains.

It lasted about 15 minutes before the battery was totally drained - more than enough time to shut everything down properly.

The Pro1200SFTU has a battery capacity of 1,000VA to support up to 600W of power from various devices. With all my devices plugged in, it took a load of only 60 per cent, which means that the UPS still has enough mojo to handle a few more devices.

The AVR is probably not so useful in Singapore where we have a stable supply of electricity.

But in less developed places, the AVR becomes more important because it regulates the input voltage to prevent sudden electrical surges that can damage electrical equipment. Still, it is nice to have.

The UPS' fast charging capability - it takes two to four hours to charge the battery from flat to 90 per cent capacity - is useful. There is also a tiny touch screen which shows your input voltage, output voltage, load and battery capacity - you simply tap the screen to toggle among the four.

The price is a little high but this device earns its keep if you often encounter power outages or if you cannot afford to lose your work in the event of a blackout.
