Thanks for the response. I acutally already own a AC/DC inverter. My concern regarding it's use is I'm not sure how "Clean" the 110 AC would be when using it on something as delicate as a computer. My hope was to find something more specialized and designed for the PowerBook. I have a DC adapter for my IBM laptop (manufactured by IBM) to use specifically for that laptop. Looking for something close to the same I guess for the Mac.
