Home theater projectors used to be exclusive to multi-thousand dollar screening rooms full of overstuffed recliners and vintage popcorn machines. Now, you can fit one inside a jacket pocket, and it's one of the coolest gift ideas of the year.

The Anker Nebula Capsule is the size and shape of a soda can, but can project up to a 100" screen onto the wall, the side of your tent, your ceiling, or anything else you point it at. It's not as bright as a "real" projector, and its standard definition picture isn't as sharp, but in a dark room or at night in your backyard, it's an awesome way to watch a movie or sporting event with friends and family.

It even has a battery built in that can last up to four hours (long enough to watch The Irishman!), and it even includes built-in streaming apps and casting support for your phone, in addition to an HDMI port that you can use to plug in any streaming device, game console, or Blu-ray player. At $222, it's never been cheaper on Amazon, but that price is only available today.

Or, for $370, you can opt for the new Nebula Mars II Pro projector. It's larger than the Capsule, but still plenty portable for backyard movie nights, and has a 720p HD picture, and five times the brightness. At that price, it's less of a gift idea and more of an indulgence, but it's undoubtedly one of the coolest deals of the holiday season.
