    I'm thinking of getting an inexpensive inverter for the car, to charge my Lenovo Thinkpad laptop from the 12v source.

    After doing a bit of research I found a few posts out there that implied that using an inexpensive inverter with a modified sine wave (as most of them are) might damage a laptop.

    But many of the brand names in laptop devices sell these things, and laptops are listed as a device that can be charged.

    For example :
    Duracell DMPI-175Inverter (prob. a Xantrex)
    Xantrex XPower Inverter 175 Plus
    Kensington Ultra Portable Power Inverter 150

    I can't seem to get the definitive answer on this.
    I know a pure sine wave inverter would be the best (and more expensive), but is it ok to use the modified sine wave types?

    I can't say either way, except that I do it routinely.
