Single unit only (not a pair). No power cable or other accessories. You would need a compatible power cable (12V DC 3A) to use it.
Appears to be in very good condition. Powers on, not tested further. Assumed to be fully working. If not I'll pay for return postage and give a refund. I do not know if it works. Minor marks.
Includes only what is shown in photos. No original packaging.
