pdomansky Posted February 4, 2011 Report Share Posted February 4, 2011 I have a 2010 Dodge Journey SXT with all options including the built in power inverter. I was wondering if anyone knows if it is a square wave or sine wave? Thanks! Quote Link to comment Share on other sites More sharing options...
OhareFred Posted February 6, 2011 Report Share Posted February 6, 2011 Found this on Google: "The output of an inverter is a very square wave, not like the smooth, round wave of a perfect sine. Some devices are inherently sensitive to the signal produced by an AC wave. Typically, these are devices that receive or broadcast some kind of signal, such as audio or video equipment, navigation devices or sensitive scientific equipment. You can see or hear the square waveform on a television as lines on the screen or a steady buzz or hum. Cleaning up the sine wave requires a series of filters, inductors and capacitors. Inexpensive inverters have little or no filtering. The alternating current they produce has a very square wave, which is fine if you just want to make coffee or run something with a simple electric motor. If you need a smoother sine wave, you'll need an inverter with better filtering. Of course, better filtering also costs a little more." I used mine to run a 22 inch LCD TV while tailgating and had no problems. Run my sons power cord for his Gameboy & played without problems.. I think just about anything you might use in the car would be OK. I wouldn't try to run a big computer or sensitive radio equipment on it.
