    Local Sine-Wave Inverter

    Where is a good local store to get a sine-wave inverter? Are coleman brand sine-wave, or one from wal-mart or anything?

    thanks

    I'm assuming you're wanting a 'TRUE' sine-wave inverter vs. a modified/filtered sine-wave inverter.

    The product in the URL above is definitely a modified/filtered sine-wave inverter.

    UPDATE:

    On the product page towards the bottom, Output Waveform: modified sinewave.

    Yeah 'modified sine wave' means basically 'fake sine wave' it is just a quasi square wave with filtering. A true sine wave inverter needs to switch at least at 20KHz or so

    Yeah I was wondering the same question, is it bad for your PC/PSU if you use a modified sine-wave inverter?

    Search the forums and you'll find an answer.

    Short: Probably not in the short term, but it might reduce the life of your PSU and Inverter. You may need to modify your ATX PSU.
