Best Battery Powered Portable Projector?

1 Answer

Answer :

answer:What projectors have you looked at? Picos are rated at 30–50 lumens, hence the ability to be battery operated… a step up in quality would be the pocket projectors (200–300 lumens) that weigh less (around 2 lbs) than the portable projectors (2000–3000 lumens / 4–5lbs),both of which require power from an electrical outlet. FAVI E3-LED-PICO and Optoma Pico PK301 Projector are top rated picos and both output 50 lumens.
