This is a small 12V monitor. The size is approximately 120mm wide and 80mm high. It was working when removed, but I can't confirm its operation now, so I'm selling it at a bargain price. I have confirmed that it powers on when connected to a battery. It is sold as junk, so no claims and no returns. How about using it as a sub-monitor for a car or a monitor for a motorcycle? Please comment first. Thank you.
