I had a small UPS (7Ah battery) at home which ran my computer for a few minutes. I now run a couple of fat leads out of it to an old car battery and it runs two computers for 45 minutes (with a bit of a smell of warm PVC cable insulation it has to be said - I should really put fatter cables on it.) I don't profess to be an expert in how it would cope with a fridge and the inductive load the motor would put on it. I am aware that heavy motors starting up can behave differently to things like computers.

 

Places like Makro do very cheap petrol generators for under £100 now which would do the job if you happened to be there to plug it in when the power cut started. Sod's law being what it is, you wouldn't be of course L

How long do UPSs work for?
