Nebula Capsule by Anker | $222 | Amazon
Nebula Capsule Series Adjustable Tripod Stand | $20 | Amazon
Okay, maybe these projectors won’t fit in your pocket—unless you have really big pockets—but they will fit in a small bag or backpack. Which means for $220 for the Nebula Capsule, or $370 for the Nebula Mars II Pro, you can project a screen onto a flat surface anywhere you go. While you’re at it, you might want to grab the accompanying tripod stand for $20 so you can set your new projector up anywhere.
