Not even 24 hours after we found the 3M MPRO110, we discovered Adtec’s AD-MP15A. This mini-projector also uses LED as a light source for 20,000+ hours of usage and works with a/v equipment, laptops and cell phones. The device has 15 lumens of brightness and a 200:1 contrast ratio. At a size of 27 x 58 x 90mm and a weight of 147g, the pocket-sized projector features a built-in 0.3W mono speaker and runs on a Lithium-ion battery that is good for about 40 min. The AD-MP hits Japan’s shelves sometime this month for ¥39,800 (~$427.00.)
