Amazon has the Nebula Capsule Smart Mini Projector on sale today for $277.99, which is down from its original price of $349. That is when you use the promo code 4CAPSULE at checkout. Nebula is a sub-brand of Anker, and it is responsible for its home entertainment products - which are largely just projectors right now.
The Nebula Capsule is a pretty small projector from Anker that is about the size of a soda can and is also portable. Anker quotes that it has around four hours of battery life when not plugged in. Which isn't a lot, but this projector is pretty powerful and for its size, four hours is pretty decent. The Capsule has a 360-degree speaker built-in, so no matter where you are (in location to the projector) you can hear the sound just fine. It does run on Android 7.1, using a modified version of Android, so you're not getting Android TV here, but you do get a slew of other Android apps here, which is definitely nice to see. The Capsule can give you up to a 100-inch picture, which is great when you are hosting a large number of people, and the Capsule will make a great projector to take on a camping trip, or even just traveling. The Nebula Capsule is super easy to setup, and probably one of the best projectors you can get for this size and price.
This item is also eligible for Amazon Prime's free shipping. Which includes free two-day shipping, and pretty cheap (usually $3.99) next-day shipping if you need it extra fast.

You'll get 30 days free (if you're a student, you get 6 months), and then it's $99/year (or $49/year for students). Prime members do get a whole lot more than just free shipping though, so be sure to check out the full benefits.
