Ill be bringing the charger to SPSP so anyone needing a quick top-up is welcome to hook up.
On the subject of inverters, to run my laptop I dont use an inverter I have a 'thingy' that runs off a battery and ups the voltage to the required and plugs straight into the lappy, seems to work ok.
Any views if this would be more/less efficient than going via an inverter ?

You just beat me to it. Save your money and power, just buy the DC to DC converter. Has a ciggy plug on one end, an output voltage selector, and an output jack. A lot more efficient than stepping 12V up to 240, then back down to whatever your laptop uses. I had a sparky test this for me at the Macquarie Uni open night a while back. The inverter used about 4 times the power!
