I have considered the option of having a UPS to keep the Genius alive when the power fails but decided against it because of the cost and the fact that all UPSs seem to be targeted at keeping desktops alive. The power conditioning benefits simply are not needed.
However being Wellington-resident I lost power for just over 12 hours this weekend.
Looking at the Genius power pack the output is 12 volts DC, implying I could use a car battery to keep it going. We have an internal garage so if I could find a way of connecting the unit to the cigarette lighter I could simply move it to the car and get it up and running. The biggest physical hurdle is finding a plug that will go into the power socket on the Genius - that shouldn't be too hard.
The nagging doubt I have is that with a VOIP unit such as this there should be options to power it from other than a mains power pack. Is there a commercial accessory available for this?
