For the next couple weeks, if you buy Anker's Nebula Capsule you can get a free $40 travel case by using the code NEBULAD7 at checkout. The Capsule is a portable smart projector that is about the size of a coke can and can project a 100-inch picture. It has 360-degree sound, charges via a USB cable, and has a HDMI cable so you can plug in DVD players, video game systems, and more. The projector runs on the Android 7.1 operating system, which lets you stream from apps like Netflix and Hulu. This isn't a projector built for a large, bright room (it's not the brightest projector out there), but is a nice portable device for trips or smaller entertainment setups. $349.
