Evolution MK-36 1C USB PC Keyboard Electronic Piano portable synthesizer Big Wheel ) Front blade moves up/downPick up price is $70. Pickup only, or request shipping cost. 8. 35 LBS. 38x 9x 4 including the height of the knobs. No USB cord included. Apparently if you plug this into your computer via the USB port you do not need a power supply and it is optional. This is not portable in the sense that it does not have speakers in the unit itself you must attach it to the computer and use the computer speakers. I do not see a headphone jack so you cannot use that
