Please do a post (not thread) search for
SINE WAVE. Here is a previous posting I made: Make sure you get a
pure sine wave inverter as it more effectively processes the frequencies [from
The Inverter Store: "Devices that require a
pure sine power inverter include: variable speed motors or power tools, televisions, laser printers, computers and telecommunications equipment, and many medical devices such as most CPAP machines. Without a clean power sources, these types of devices simply will not run, or you may risk shortening their lifespan and causing them to fail prematurely."].
