Hi Just a quick OT Question. I have a modified 600w 12v -240v inverter and
it ran my PC fine but would not run my wife's straightening irons (75W)
whilst we where camping, (Not happy wife) is this because they have
electronic temp control. wouldn't charge a APC UPS either. Is there any mods
that can be done to the unit to round the output abit?

You didn't have it on half power did you ? This sometimes uses as series diode.
The inverter won't like supplying half wave rectified ac.

I can tell you a funny story about this too if you like ! ;~)
