AAXA P400 Native 1080p Short Throw Mini Projector with 2 Hour Battery, Onboard Media Player, 30,000 Hours LED, HDMI/USB/microSD Inputs, LCoS LED Portable Projector for Business and Home Theater Movies

Great mini portable projector but what let's it down? Only supports 64GB SD card and USB. And the only video format it plays from them is .avi - For something so new why only avi files?. Nobody uses them anymore. We need .mp4 and .mkv support. Please update the firmware!

This was my third attempt (out of four) at finding an affordable projector for my basement theater. The big problem is I only have 8 feet of distance from the lens to the screen, and I want a 100 inch picture to fill the space just right. This eliminates roughly 95% of the projectors out there. Well, the AAXA P400 is almost perfect in many ways. NO wonky bluetooth, no finicky WiFi, no sluggish GUI's and apps, and it broadcasts a nice 100-inch picture from the ceiling about five feet away from the screen. I use a Roku Ultra or PC for content through a Yamaha digital 5.1 receiver with 4 HDMI inputs. The P400 is a very nice unit, however I was hoping a tiny portable outdoor projector would fulfill my quality home theater needs. The picture clarity is nice, and I was almost completely satisfied every time I fired it up.. But the brightness, color quality and depth just weren't there. Almost, but not quite. I'm somewhat familiar with projectors over the last 20 years or so, and it's nice to see what the latest LED technology has done for the industry, but the only short-throw options I could find above the AAXA P400 were $700+ brand names that still use DLP tech with those expensive halogen bulbs that start burning out after about 5,000 hours. So I was somewhat happy with the P400, but then I would fire up the first projector I bought (that's now in my larger living room because it's a standard-throw), and would almost be shocked with the brilliant picture. Much brighter, and much more color depth for less than $200. I contacted AAXA, and they showed me great customer service, but I still couldn't get that little bit of 'extra' out of the picture. Before long I realized 30 days have passed, along with the possibility of return or refund.. Aaannd, that's when I suddenly stumbled on a shorter-throw Epson laser (not halogen) projector for $600 that I wish I would have found back in the beginning of my search. Pow! Home theater? Yes, finally! My fourth and projector purchase in about 5 months. The AAXA P400 is actually a very nice unit in many ways, but you need to keep in mind it was designed for portability and backyard movie nights. It would be great for kid's cartoons or movies on camping trips, but if you want something more you'll have to spend considerably more. *Update to original review.* I forgot to mention the stuck focus wheel. I had to place a small screwdriver on the wheel to pop it free, then it functioned well. It's scary to do this, but thankfully it worked. *This review is NOT part of a promotion.*

The device seems like it could be nice, however the focus wheel is so incredibly still it is impossible to turn. It does appear to be bright enough, albeit entirely out of focus from more than 6 inches from a wall

I'm moving overseas in a few months, so was needing something to replace my Optoma P2 4k and Epson 3700 projectors. Compact size, 120/240vac, 1080p, short throw, 400 ansi lumen specs caught my attention. I want my entertainment system as compact as possible, minimalist concept. *** Been using this for a week or so, mostly as a PC and Chromebook monitor replacement and for streaming Netflix, Prime, YouTube. I have a Carl's 5'x9' (120in) projector screen with 1" conduit frame. My suggestion is find an ALR screen for the best picture in brighter rooms and tamp down that ambient light. *** Alignment: There is no keystone adjustments. Assumption is that the screen or wall is flat and square. The projector needs to be exactly level (perpendicular) with the screen/wall. The top of the projector will be the very bottom edge of the image by line of sight. So if the level projector height is two feet as measured from the floor to the top of the projector, then the bottom of the image will start at two feet also. This projector shoots up from there. Knowing this, you won't have much keystone issues. If you try to project at any irregular angles, other than square on, then the image will be out of square also. If you are looking for perfection, then this isn't for you. Close enough for me since I'm not OCD. *** Short throw: I like the short throw part of this. It isn't UST like my Optoma P2 (against the wall), but at 78" from the screen/wall, you will get a 104" wide by 55" tall image (roughly 116" diagonal). I have my P400 on a metal tripod just in front of the coffee table. A smaller image will net a brighter picture. *** Focus: The focus part is fun. It is a very course focus wheel. The wheel is stiff, so an extra good time with that. Doable. The focus clarity is not uniform throughout the image. Specifically, it is slightly off in the very upper corners, and slightly off in the very middle. When doing spreadsheets, it's slightly annoying, but then you get used to it, and it ain't but a thing. Playing a modern movie on Netflix or Prime there is no noticeable focus issues. *** Image quality: So, for the price, you are not going to get deep blacks, and whitest whites. At 400 ansi lumens, it is paler than my $3200 Optoma P2 obviously. You don't need a black out room for this. Close the blinds or pull the curtains and it's fine. Any projector will have issues if the blinds are up, sun shining in or on the screen. I played a little Shadow of the Tomb Raider, and it's noticeable that the lack of brightness as well as the missing blacks and whites do affect gameplay a bit. My PC has a 5600x and 3080 12gb OC so the quality potential is there on the PC end. Maybe just need more tweaking. *** Sound: Yes, there is sound. Not the best at all. Tinny. Gets plenty loud enough. I am using a "4K@60Hz HDMI2.0 Audio Extractor Converter with Bluetooth Transmitter", so I keep the projector volume at 0 (not mute). In mute, there is an irritating OSD (on screen display) that says "mute", and never goes away. At least at volume 0, there is no OSD. So I have my JBL Charge 5 Bluetooth as sound. This does not have wifi or Bluetooth built in. *** In a nutshell: The closer to the wall, the brighter the image and the better the focus. I won't be returning this. It does what I want it to do and is beyond my expectations. I will take this with me when I travel overseas. Nice and small and compact. Simple to use. Very basic menu with preset image, or user adjustable image quality settings (color, contrast, brightness, etc.). Keystone isn't perfect, but close enough for me; don't notice watching movies. 4 stars due to imperfect focus, could be brighter, could have better contrast.

Like I said this is a small projector. It cannot connect to WiFi, which might not be that much of an issue since because this doesn’t seem to be well implemented on other similarly priced projectors anyway. There are a few concerns, this is a loud projector because of its small size the cooling fan also needs to be small, but that also means that it needs to spin much faster to move the same amount of air. Focusing is not well implemented on this projector. There is a little wheel that you just cannot get in the right spot no matter how you try, however since there is NO keystone correction you could probably fix it by moving the projector around. I really wanted to keep this projector, but the luck of keystone correction means that there really is only one position this can go, whether it works for you or not. The remote, which is also not great has keystone buttons, but it has no effect, so I assume it is for their other models.

The price is quite great for what you get (1080p, short throw) after comparing other projectors. The short throw is nice and can get ~48inch screen size when ~3ft away from wall (decent for tighter spaces). Awesome picture in the dark (not bright enough for light), quiet fan, and small size. The design flaw is that the HDMI slot is too close to the aux input to use an Amazon 4K firestick (did not try any other firesticks so perhaps it's an isolated issue to 4K stick). The 4K stick blocks the aux jack slightly and you cannot plug anything in. If the aux jack was spaced out or put on different side of device it would be greatly improved. We ended up returning as we realized for our set up and uses this one didn't really work how we expected/intended. But otherwise we liked it. We preordered a different projector "Screeneo U4" but was a lot more money, so if budget and short throw is important - this AAXA P400 is great.
