Inverter usage

[PhotoMan]

I'm about 85% electro-idiot; understanding just about enough to keep me out
of trouble. Scenario: I have a new Compaq laptop I wish to use in my car
for downloading files from my digicam. I also have a year-old RayoVac
inverter rated at 350W, 120V, 3A continuous output which I'd like to use for
AC power for the computer, and to recharge the LiIon batteries for the
camera. Is the sine wave output of the inverter likely to be too 'impure'
for this usage?

TIA

Computers use switch-mode power supplies (SMPS) so AFAIK this would not be a
problem.

Most of the newer switching power supplies don't really care if the AC
line input is a sine wave, since it gets rectified to DC as soon as it
gets into the power supply. And these newer PSes are very tolerant of
the incoming line voltage. They may accept anything from 95V all the
way up to 240VAC. But look on your power supply to see what its ratings
are.
