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.

Jim,
Thanks for the inverter suggestion. 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.
Stan
