AAXA P300 Portable Projector Review

Marc Davidson, April 5, 2013


Low audio volume. The P300's 2-watt speaker isn't loud enough to hear from even few feet away. If you need sound, plan on using a headset or external sound system.

No zoom. As with most small projectors, the P300 leaves out a zoom control, so the only way to adjust the image size is to move the projector.

Hard to focus. The focus thumbwheel on the P300 changes focus a lot with very little movement. It's not hard to get the focus close to its best setting, but it's far too easy to overshoot and wind up merely close to the best.

Battery is hard to install. If you get the optional battery (which you should), be sure to order it with the projector, and make sure it will come installed. The battery connector, which is on a wire, is hard to plug into the projector unless you have a pair of long needle-nose pliers with a right angle bend in the tip. I tried it twice with two different projectors, using standard long needle-nose pliers, and found it highly frustrating both times.

Scaling artifacts. One image quality issue the P300 shares with most directly competing projectors is scaling artifacts. Even with 1280x800 image, it adds unwanted extra patterns to large areas filled with repeating patterns of fine lines or dots.

Scaling artifacts shouldn't show up when the input signal is at the projector's native resolution, but I've seen them with every projector I've tested that uses the same DLP chip as the P300. As I've reported in other reviews, Texas Instruments says that there is no scaling. However, it also says that the issue is likely due "in part" to the chip's architecture, although it hasn't provided an explanation beyond that.

The good news is that unless you use patterned fills in your graphics instead of solid blocks of color, you probably won't see these artifacts. If you show any images with closely spaced lines or dots, however, you will almost certainly see them.


The P300 shares many of the same advantages as competing models rated at 300 lumens, and it fits in the same general category. Compared with pocket projectors, it's larger and heavier, but still small and light enough to take up very little room in a briefcase or laptop bag so you can carry it without much effort. And although its brightness on our tests was significantly lower than its rating, it's still enough brighter than a pocket projector to give you a noticeably larger usable image with any given lighting conditions.

The big advantage of the P300, and the main reason to consider it, is its ability to run on batteries. Other projectors with a similar size, similar connection options, and a similar ability to read files directly from memory are brighter. However, the P300 is the only one among its most direct competitors at this writing that can work without AC power. If you want the freedom to show images without being tied to a power outlet, that may well make the P300 your preferred choice.

Joey - I've had the same issue. The projector goes off as if overheated and then doesn't stay on after cooling. I had another adapter in my bag and it was fine with that adapter. I tried others and only my spare would work. I plan to call the company.

Would anyone happen to know why after an hour of operation the P 300 would shut off and the error red light flashes? I thought this unit overheated so I let it sit for an hour, try to turn it on and it automatically shut off. I also tried to charge it and the green indicator light would not come on. Could this be a charging adapter issue?

Can anyone chime in and help me out?

How does this projector perform in a well lit room?

Hi Mel! Yes, I own a MacBook Pro and have watched many things already with it! You will have to purchase an adapter which can be easily found on ebay for pretty cheap for the VGA port or the HDMI port (my preferred port as it gives you hd images and videos)

I hope this helped you!

Hey I just have this thing for 4 month now. Perfect picture and very nice image quality but the fan noise is horrible. High leveled and too loud. Tried to replace the fan with a more quiet one but it detects the wront fan and shuts down. So I really want to replace this device because of the noise....

Could you write something about the sound level (fan noise) for the P300? Compared to some other devices. Or even better provide a recording of the sound.
