Typically the lower priced inverters are Modified Sine Wave (MSW) rather than the more expensive Pure Sine Wave (PSW) ones (although the prices are getting closer together.

The MSW models run most everything including laptop computers and any others which transform the incoming 120V AC to 12V (or 5V or 19V) DC. The two things which don't seem to react well to MSW are laser printers and things with 120V motors.

I have been running a cheap MSW for 10 years running TV, stereo, DirecTV box, power inserter, laptops and cell phone chargers. Never a problem. YMMV
