Needs a power adapter - NightStar 4X50 mm Digital Night Vision Monocular w/ Camera and Recorder

The binocular is decent overall for it ability to see in the dark you can see a long way in low lite and an ok distance in pitch black with the infra red illuminator the only drawback is the batteries you done get that much time it takes 2 and they are 11 to 14 dollars a piece so you pay min $22 for about 45 minutes to an hour of use and energizer is supposed to make a rechargeable but you can't get them unless you active military so an AC adapter would be the best alternative but I can't seem to find one for it
