However, looking at the sinewave stuff, it would seem that my 90w (an APC BackUPS Pro) may not be suitable (plus I think it needs recharging), so my other one (an APC SmartUPS Pro) would probably be better suited...
Just on a side-note, I get UPS' pretty cheaply from a monthly computer fair, I got my SmartUPS Pro for £10, and I got the other one for free (it wasn't powerful enough for a 21" monitor, even on mains power!!!)...
