AAXA Pico Projectors

these seem expensive for such a low lumen output.

Their portability are worth some of that cost though. These don’t replace a boardroom projector, but work in small venues where you have control over reducing the ambient light. If you have a room with large windows letting in a lot of light, these pico projectors don’t perform that well. I’ve seen 400 lumen ones and they do ok. But any of these would be nice in a room you can darken. I sure like the small form factor as I travel a good bit with a projector.

Remember that not everybody uses projectors for meeting rooms. I have a few pico projectors for Halloween effects, and the work great.

The 450 Lumen one AC only specs make no mention of any kind of power.
