I got my inverter from Lenovo about 9 months ago. I don't remember the cost but it wasn't much. Get it specific for your laptop. I think one-size fits all. Check Fry's Electronics.

I have the Lenovo W530 laptop. The power supply that comes with it puts out 20V, 8.5A. Would I need to find a DC to DC inverter that puts out 8.5A? Is there an amp range that is acceptable? Who has this inverter? I would need it within a week or so and so someplace in town is better than ordering it from the internet.
