Cool gadgets are always a great gift idea for teenage boys and this pocket-sized projector is definitely a cool thing to pull out of anyone’s pocket. While it won’t give your 4K home projector a run for its money, its combination of size and picture quality are downright unmatched in the category, allowing you to enjoy native 1080p images as big as 150 inches. It’s actually pretty nuts for a projector of this size, as it delivers 200 lumens of brightness, a 3500:1 contrast ratio, and 16.7 million colors, complete with instant focus optimization, automatic vertical keystone, and 100 percent offset to ensure you get a perfectly-aligned rectangular picture each time out. As you can imagine, though, the battery only lasts long enough to let you finish a movie (and a few short videos), so you’ll also want to keep a power bank around to keep it juiced.
