My suggestion, which I have never tried, is to get a UPS with the right
wattage and that support 240V out but variable (90V-300V) input. Just a

PS Please don't make the mistake that a certain US supplier made with kit
shipped to UK and specify 16A connectors which required special wiring (over
standard 13A in the UK) as at 240V the current is lower by 240/110 :)
Measure watts, not amps. Unless you have a weird PSU of course.
