AAXA P300 Portable Projector Review
Brightness. Our test sample of the P300 was substantially less bright than its 300-lumen rating. With the projector plugged into a wall outlet, I measured it at 148 lumens in its brightest mode, or 49% of the rating, and 136 and 70 lumens in its other preset modes. As a small plus, thanks to its RGB light source, it delivers the same color brightness as white brightness. When it's running from the battery, however, the brightness drops by about 33% in each mode, to 99, 91, and 47 lumens.
Given the rule of thumb that you want an image brightness of 16 foot-Lamberts (fL) in theater dark lighting and 40 to 50 fL with moderate light, and assuming a 1.0 gain screen, the measured brightness makes the P300 suitable in its brightest mode for a 54" diagonal image with the lights off or a 30" to 34" image with moderate ambient light.
Good brightness uniformity. The projector earned a high score for brightness uniformity in my tests, at 81%. However, the change in brightness happens over a short enough distance so that on a solid white or color screen it's easy to see that the center area is brighter than the sides. With the test unit, the brightness also dropped noticeably over an even shorter distance in one corner, which is outside of the designated ANSI test points, so it's not reflected in the measurement. Even so, with the screen broken up by text or graphics, the changes in brightness are hard to see. It is unlikely that anyone will find them distracting.
Good Connectivity. The P300 offers a fairly complete set of connection options for a sub-two pound projector:
- 1 HDMI
- 1 VGA In (a proprietary port for a supplied adaptor ending in a male DB-15 to plug into a computer)
- 1 mini plug AV IN (for a supplied adaptor ending in female RCA connectors for composite video and stereo IN or for a $19.99 optional cable for iPod, iPhone, or iPad)
- 1 Stereo mini plug OUT
- 1 USB A and 1 microSD card slot (for reading the most common audio, video, and image file formats directly from memory keys and cards)
- A final connection choice is a $19.99 optional adapter cable for the Samsung Galaxy S3 or Galaxy Note 2.
