AAXA Technologies P4 Pico Projector Review
We measure the sound of the room, and the sound of the room with the P4 turned on, and check the difference to see how much noise it produces. An increase of about 7dB is very little, but when it sat on our desk for a couple hours buzzing away before it died, we got a little annoyed.
This pico does not heat up very much. The exhaust fan shoots out air at a temperature that is 18.6º hotter than the room temperature, which is about a third of the usual amount of heat for a video projector, and still very cool for a pico projector.
All of our pico projectors cost about the same to run for an average year of use: not very much. We also mark an average year of use as if you were using this projector as your main display; as you would a television. It's going to cost even less than the $2.73 we have posted here.
The light source is comprised of three colored LED lights which are tested for 20,000 hours. You cannot replace these lights, but 20,000 hours should tide you over until you want to throw this thing out anyway.
