The Kodak Luma 150 is a portable theater that very nearly fits in your pocket. It's not the highest quality projector in this list, but it weighs less than half a pound, manages the equivalent of an 80-inch screen at 12 feet, and at $200 you'll still have some money left over for that Netflix subscription. You can stream files via Airplay or Miracast, or plug in a microSD card, USB cable, or HDMI cable. The HDMI port means you can hook it up to your FireStick or a Roku device. The display is bright enough in a dark room, but it struggles in the daylight. Still, if portability is your priority, the Luma 150 is hard to beat.
