This is an analog TV, but it can't receive broadcasts anymore, so it would be used as a monitor. Composite input is possible via the AV input terminals on the side. I used it as a monitor for a digital camera using the yellow and white RCA cables. Power is supplied by either three AA batteries or an external 5V power supply with the same connector as a common PSP charger. However, it's an old item, so I can't guarantee its functionality. The item will be shipped as the main unit only. Please feel free to ask if you have any questions. Thank you.
