This Audiovox D1420 portable DVD player is just about an inch more in diameter than the DVD itself. The tiny player features a built-in 4.2″ 16:9 LCD widescreen and battery life is quoted at 2.5 hours, so you should be able to watch most full-length movies on a single charge.
Measuring just 5 3/8″ H x 6 1/2″ W x 2 1/4″ D, and weighing just over 1 lb., the player features a rubber frame around the case to protect from shock and to make it easier to grip. MSRP for the player is $129.95 USD, but it can be found on the street for under $100.
