AAXA P4-X LED Portable Pico Projector, 125 Lumens, Li-Ion Battery, Media Player, 20,000 Hour LED Life, Pocket Size, DLP

Using on a MacBook Pro. Used Mac MiniDVI to VGA adapter (not included) to connect to the VGA cable supplied with the projector. Will eventually get a MiniDVI to Mini HDMI cable for normal use but the VGA quality was excellent. In a normal daylight room with overhead florescent, the brightness was sufficient on battery power to view the display on a white wall 8 feet. At 25 feet, projection is still good and size of picture is good, but blinds to block sunlight coming in. On the power adapter, it is noticeably brighter. If you are using this for a business meeting in a small conference room where you can dim the lights, it should be good enough to get the job done. If a large meeting room where a larger size is needed, worse case you may have to run it off a power adapter and shade the ambient light. In my opinion, it rivals the bigger and bulkier units. Note I was also running on battery power out of the box, not sure if they recharged it or not at the factory.It came with a mini to standard USB cable, about 6 inches in length, a cable for component video connectivity into a phone connector (TRRS) that is on the receiving side for the projector, a 3 foot mini VGA (projector side) to VGA standard cable, 1/8 inch. There is a headphone port 1/8" TRS. I did not test the audio quality because I tend not to use audio in my presentations beyond my own voice (I figure if I am not doing the talking live, what is the point of me being there?).It comes with a small remote. Not sure I will ever use that since I tend to control my presentations through the keyboard on my machine. It also comes with a flexible three point leg tripod that is 4.5 inches tall before adjusting the legs. It is packed in decent box worth keeping it organized in if you don't end up using some other kind of bag box. I will probably get a small camera/aluminum box to carry it in.The power adapter has about 4.5 feet of cable length. It outputs 12vdc at 2A, cylindrical jack with outside negative. 1/8" diameter.Shipped with a glossy two sided business card for tech support to ensure customer satisfaction. 714 area code number, email address, hours of operations, street address of AAXA Technologies. Looks like they are seriously interested in satisfied customers.The 32 page users guide is 3.5" X 5" in size, full of pictures. I did not actually read it, or need to, but given the amount of pictures it looks pretty simple if for some reason someone really cannot figure out how to use the device without it. I found the device to be pretty intuitive.When powered on it gives the option for using the mini SD card (not supplied but a port for one is on the front of the device), USB, VGA, HDMI, Composite or settings. It was pretty simple to navigate through by going left and right (not up and down). There is a back button, ok button, up, down, left, right, power on/off, and manual rotation focus control.To power on/off, hold the power button down for a few seconds. Pushing it with immediate release sends power to the unit but it does not stay on.The size is as the picture shows. It fit nicely in my hand the very same way. 5.5"X2.75" by just over 1"… weighs about as much as my mouse and iPhone held at the same time (I know, technical….but I did not have a scale. In short it is light).Given all that I really like it and it will do the job I need it to do. For the price I could have probably got an entry level larger projector, but the whole point was that I don't want to lug around a whole projector especially on a plane.The negatives. The fan is a bit loud, but I was in a room by myself when I tested it and no other noise. It is likely not any louder than any other projector that I have ever used. The room was measuring 40dB with the device off, and 54dB with the device on. The difference between a quite home or whisper conversation and a normal or quiet conversation. Talking at my normal volume, the meter was at 86dB. The meter I am using is an iPhone app, so it's likely not accurate or calibrated but based on the reference points of normal ambient noise and my normal speaking voice, you should get an idea of how loud the fan really is (I have good ears so it sounded loud to me relative to no room noise..but not so loud one cannot talk over it or find it too distracting in a large room…I was standing right next to it).The lens assembly is recessed in the unit so one should never accidentally touch it unless they go out of their way to stick a finger down 0.75" diameter hole in the front that leads to the lens. Still, a cap would be nice just to keep dust out. Then again, there are a lot of airflow vents on this device, so can you really keep dust away from it? Speaking of airflow vents, you can see the circuits through them which means they did a good job in packaging everything…just do not spill anything on it.Some have said it lacks in features that other pico projectors have for playing multimedia without a computer. I'm not sure the benefit of being able to put a powerpoint on a USB or SD card and playing it off the projector. If I am projecting, I'm probably trying to cause the audience to respond in some way or ensure they are informed. Not knowing what questions they may have in advance, I'm going to have my laptop or other device with me anyway.Bottom line, I am pleased with the purchase because it is going to do what I need it to do: Project big enough and bright enough to conduct business meetings while being compact enough that I can easily put it in my carry on with my laptop.

I have the AAXA P4X and the AAXA LED PICO projectors and the LED PICO is a much better projector except for the brightness/number of lumens. The LED PICO cost a 3rd of the price though.I really wanted to use this projector but there were to many downfalls compared to the LED PICO:• The P4X does not support the AC-3 audio format which is the standard format in HDTV broadcast, DVDs, Blu-ray Discs and game consoles, etc. So you would have to use an app like HandBrake to re-encode any videos containing this audio format and convert the audio to AAC. The LED PICO does support every video / audio format I have found so far.• The fan is much louder than the LED Pico. this wouldn't be a problem normally but in my application I have the projector mounted to the wall above my head and it vibrates the wall and makes a lot of noise.• the user interface is painful to use compared to the LED Pico. If you press the right button before bringing up a the menu it jumps to the next video in your library. On the LED pico, the right buttonis volume up. And there is an annoying delay when clicking any of the buttons where it takes several seconds to react to your input.• the screen size is not as large was the LED Pico so you have to move it further back to enlarge the image size. Plus the LED pico has a higher native resolution because it is qHD instead of wVGA.• the LED Pico supports several sound formats including surround sound.The only benefit I can find with this projector is that it is a lot brighter than the LED PICO. but all the downfalls are outweighing that benefit since the price is 3 times more. For $115.00 you get a lot more bang for your buck with the LED PICO in my opinion.

The AAXA P4X Pico projector ($300) is a lightweight battery-operated, palm-size video and monitor projector. I purchase it for conducting presentations on the fly for my photo instruction business. My instructors meet in public indoor locations for our 2 hr classes and often do have access to power or a screen for projection. Powered with LED light, the PIco projector is very effective in a darkened room for up to 10-12 feet and with a 5 foot screen projection. The battery life was about 1.5-2 hours; sufficient for a 2 hour class. I even projected a 90 minute movie for my kids outdoors in a park. Their are many connections available. I have used the VGA with and iPad retina. There also audio in for its speakers, USB connection or Flash drive , HDMI standard video and an SD card slot for viewing photos or videos. Check for formats for proper viewing. Haven't tried it yet. I will amend my review later. I connected the Pico Projector with supplied cables. The surface texture is rubber like; great gripping. I mounted the projector on my photo tripod. That's cool! It also came with a mini tripod for table top projection.What I liked:Small size. PortableBattery operated. Good life. 3 hours to recharge to first time.Supplies cables. Though may have to find adapters to other devices.Connection optionsTripod mountedButtons and menus easy to useSurface texture easy to grip.Bright projection in small spaces for small groupsMy concerns:Had some issues keeping the supplied VGA adapter cable connected to unit. A little loose in port. Had to use tape to keep it from falling out. I think the weight of the cable a bit too much. Trying another cable or HDMI next time. Does not come with minHDMI/HDMI cable. Because this issue, 4 stars other wise would have been 5.My PlansI will try the remaining viewing options and connections. Test battery life and cables in other scenarios and conditions.Connect to other devices; laptop, disc player, a phone( with adapters) that has video out. Connect speakersOverall very pleased with this projector. John Perez, Owner, Indy Photo Coach.com
