- Reviewed in the United States on March 31, 2018This projector fulfilled my dreams after several months of searching, purchasing other products and failing to find a match for my needs. I wanted a light weight, portable projector that would work off of my iPhone, set up quickly and show a great picture in a moderately light room--big hopes and expectations. I tried the new Sony, and it was a total failure--dim images, poor technology integration, very poor performing app interface. I tried the Amazon DB power, and it was just cheap--I couldn't read any text on the screen.
The Asus is totally great! It throws out very sharp, clear, bright images. It is very small and light and easy to set up quickly. The ultra short throw is fabulous. I put the Asus on a small table about five feet or less from the screen, and it makes a big, clear image. That saves a lot of space in the room, and you don't have to worry about people walking in front of it or knocking it around. It warms up fast and is ready to go shortly after you turn it on. I don't worry about turning it off and on because it is so quick.
In one of my regular settings I don't need to turn the lights off. In another room with plenty of daylight, I turn off the lights and adjust the blinds and still get a functional image. Words show up sharp and clear.
I recommend that you don't even try to work off the battery. It takes the image quality and brightness way down. But that's okay with me because the whole package is so small and light that I can carry a power cord without much extra weight. Because of the ultra short throw, I find that a short adaptor cord usually works fine without the need to carry a big orange cable around.
I add a Bose speaker to the system for great sound when I want to show a YouTube. I use a headphone adaptor to connect the projector and speaker because there are always complications with bluetooth when there are other devices, such as my hearing aids, in the vicinity. I prefer a smooth presentation with no tech glitches. All the little connectors and cords fit into the case with the projector, except for the extra wall extension cord. So all I carry is the projector case, the Bose speaker and an extension cord. It all fits into a shoulder bag.
The projector has all the connections I need--HDMI is the big one for me. The projector works really great with my iPhone through the HDMI. Be sure you use the Apple digital AV adaptor, or nothing will work properly. Do not use third-party adaptors with iPhone! The Apple adaptor makes everything work perfectly with the iPhone.
I strongly recommend purchasing the little Manfrotto stand that screws into the bottom of the projector. It makes it very stable and you can adjust the throw easily.
This projector is small but mighty. It would be great for throwing a big picture on a wall for viewing movies at home. I love it and would recommend it to anyone who needs a small, lightweight projector for informal settings or even on-the-go business needs.
- Reviewed in the United States on June 16, 2023I am so frustrated trying get this projector to connect wireless until I finally gave up. I was upset but I finally hit the ceiling when my ASUS laptop stopped recognizing it and the last few times I’ve tried I can’t get it to connect with the HDMI to my laptop. I threw $500 in the woods and it felt great.

- Reviewed in the United States on February 15, 2021I purchased the projector with WiFi dongle in order to project wirelessly from my iPhone. However, the ASUS app doesn't support iPhones more recent than iOS 11. This limitation isn't mentioned on the product page, unfortunately, which deceptively implies it will work with all iOS and Android devices.
- Reviewed in the United States on December 20, 2019small size, good quality. can't see it so great in the day unless all curtains are closed. we only use it at night. I've used many projectors for work and home and not many can be used without lights off. that being said, this one is pretty great. nice small compact size, love the case and the build quality. I feel I got my money's worth. the screen size can fill an entire wall which is many times larger that my 65" tv that I have. my family enjoys movie night with this little unit. works for me! I bought it for my side DJ mobile service I own; works well. easy to transport; fits in my backpack, don't even know it's there!!!!!!!!!
- Reviewed in the United States on July 28, 2018Disclaimer: I only received this projector yesterday, so my review is only for my initial impressions. I will update the review later if my opinion changes as I use the projector more.
I love this little thing. It is EXACTLY what I was looking for. I looked at the Nebula series by Anker, ZTE Spro, and many other unknown Chinese brands that are sold here on Amazon. After spending a lot of time reading the reviews, I learned how many of these projectors failed to live up to the hype - or they lacked enough lumens to be used in any setting except for complete darkness. Then I came across the Asus P3B and everything seemed to line up for what I wanted :
Short throw? Check.
Optional battery power? Check.
Compact and easy to travel with? Check.
Enough lumens to be used in a low light setting? Check.
Native resolution was at least 720p? Check.
Some concerns I had before buying: Many reviewers complained about not being able to get wireless USB adapters to work. I found that it indeed does have problems with USB wireless adapaters, at least for the one I tried to use. It just did not recognize it and the USB adapter I tried was an Asus adapter (ASUS USB-AC53)... go figure. Others mentioned it would not work with Miracast connectors. In my case, it works BEAUTIFULLY for me. And it does not require a wireless adapater to be used in addition to it either. I just simply plugged the Miracast adapter (specifically I have the Microsoft Wireless Display Adapter) in to the HDMI and USB ports on the projector, switched the input to HDMI and bingo - there it was. I connected with my Surface Book 2 and I instantly had an extended display. The picture quality is superb. The colors are rich and the projector instantly powers on.
Asus includes a soft case but I don't trust that for traveling where the potential of damage could occur, so I bought the Pelican 1200 case to use with this projector and it perfectly fits the projector, power cords, and remote.
I love this thing and will be using it a lot in the future! I will update my review later if there is anything relevant to add.

4.0 out of 5 stars The Short throw, with big screen size, and the colours are good
I just received my order today. It is a well packaged, and beautiful projector. The remote doesn't seem to respond well. I have several regular and about four cheaper mini projectors, but have not encountered difficulty with a remote like this one. It is too confusing. All in all, I like the Asus P3B projector with its short throw, and hopefully I will be able to overcome the pitfalls of the controls. For such a nice mini projector, you should have done a better job with the remote control.

1.0 out of 5 stars High Ratings But Not Bright Enough - Good Amazon Return Customer Service So Far
Having read all the good ratings of the P3B I expected the brightness and resolution to be better. I had planned to use it in a week long meeting in a hotel projecting text from a laptop computer. In a meeting room with the blinds partially closed it was hard to read the projected text from a WORD document. Fortunately I had an HDMI cable and the TV monitor was connected to my laptop computer instead. Maybe my expectation for a mini projector was too high but I have a nine year old NEC portable projector, pre-HD, and it projects a significantly more brighter image. After having spent about $800 I was very disappointed but when I called Amazon and I shared my concerns and there was no hesitation for the agent to offer to send me a return label. I packaged the projector and sent it off and it is apparently "out for delivery". The good Amazon service will be confirmed when the money for the projector is refunded to my credit card.
