The Nebula Capsule 3 is a highly portable, compact full HD projector with good smart-features, vibration for on-the-go use, and decent battery life. The Nebula Mars 3 is built for outdoor durability and more powerful performance. If you want a projector that works indoors and outdoors, with high brightness, durability, and long battery life, the Mars 3 outperforms the Capsule 3 in most real-world use.
Let’s make long story short: If you want something ultra-portable and easy to carry anywhere, the Capsule 3 is great. But for an all-around, more capable projector especially outdoors, with larger screen sizes, better durability, and stronger presence the Mars 3 is the better investment.
