Anker has been expanding their brand over the years from just making chargers. They now make some great portable projectors, and now, their smallest portable projector, the Nebula Capsule Air, is down to $249.99 (originally $399.99) for Prime Members after a $150 discount during the October Prime Day sale. This is the lowest price this portable projector has been, according to price-tracking tools.

Portable projectors must work independently of an outlet and be easy to cart around. The Nebula Capsule Air can do both, measuring just 5.5 x 2.7 x 2.7 inches (HWD)—that's slightly bigger than a regular soda can. The battery isn't great, but considering the size, two hours is fine (you'll be able to watch most movies in one shot). Where this projector falls short is in the brightness, reaching a mere 150 ANSI lumens. That means you need to get your space dark if you want to see a good image. If you have ambient light outdoors and you're hoping to use this projector, it might be washed out. The native resolution is also just 720p, although it supports 1080p input in HDR.

PCMag gave this projector an "excellent" rating on their review, pointing out how the HDR makes shadows look much better, giving it props for the Google TV OS (which is my favorite—it lets you seamlessly cast your phone to the projector), and praising the twist-on stand that allows you to position the image easily on your screen, wall, or ceiling.

Portable projectors need a good keystone; by their very nature, they will be moved a lot and the image will be constantly out of focus. The Nebula Capsule Air has an excellent keystone, with autofocus and automatic horizontal and vertical adjustments.
