We recently bought the cheapest cigarette lighter to AC inverter from the electrical
shop where we bought a camera
It charges the camera fine and runs the computer fine. It also runs the computer printer.
Don't worry about Pure Sine Wave its not necessary - and very expensive.
unit should cost less than $100 anywhere in the modern world.
Ours even has a USB power port for Ipods etc
See website: 150 Watt Auto/Air Power Inverter - Slimline Style
