    Can I use my portable electric compressor in a basement?

    I recently bought a Coltri MCH-6 compressor. Since the only 220 outlet I have in my house is in the laundry room in the basement, is it ok to fill tanks there or do I need to put the compressor outside and run the power cord thru the window? Reason I ask is just for Radon and humidity concerns.
