300 ANSI lumens, Android TV built-in, 640g portable, 10-hour battery, 1080p. Dark-room-only portable projector. Weakness: 300 lumens unusable in any lit room; 2–2.5hr runtime at max brightness; weakest audio in class.
Anker Nebula Capsule 3 — 300 ANSI lumens, Android TV built-in, 640g portable form factor, 10-hour battery, 1080p native resolution, palm-sized cylinder. Available at major online retailers. 300 lumens is strictly dark-room-only — any room lighting washes out the image completely; 2–2.5 hour runtime at maximum brightness limits extended sessions; the speaker output is the weakest audio in this comparison; battery-powered portability comes at the cost of all image quality metrics; best suited for bedroom or camping use only.
The Anker Nebula Capsule 3 is the only projector in this comparison that fits in a bag and runs off its own battery, which is the entire point. 300 ANSI lumens limits it strictly to dark rooms — bedrooms with curtains drawn, tent interiors, hotel rooms with the lights off — but within those conditions, native 1080p projection at 60 to 80 inches looks surprisingly competent for a 640 g cylinder. Built-in Android TV gives you Netflix, YouTube, and Prime Video natively without dragging along a Fire TV Stick, and the 10-hour battery actually delivers around 2 to 2.5 hours at full brightness for sustained projection. The built-in speaker is the weakest audio in the comparison, and the lumen ceiling means a single ceiling lamp washes out the image. As a travel and camping projector it is the easy recommendation; as a primary home projector it is not the right tool.
Pros
- 640 g cylinder with 10-hour battery for genuinely portable use
- Android TV built in — no external streaming stick needed on the road
- Native 1080p resolution scales to a watchable 60–80 inches in dark rooms
Cons
- 300 ANSI lumens means strictly dark-room use only
- Built-in speaker is the weakest audio in this comparison
