Ease of Use


The Good

  • Real 720p Resolution
  • Small keystone adjustment
  • Simple user interface
  • Decent colour in dark rooms

The Bad

  • Not usable with any ambient light
  • Very loud fan
  • Audio out jack not functional

This projector also comes in an Android version called the AUN C80 UP. The best value is found in the basic version, the regular C80, since the $50 extra is a significant jump in price with no increase in image quality. For that $50, you’re better off buying a used PC or finding a separate Android TV box with better specs at less cost.

The Aun C80 is a basic 720p projector offering approximately 240 ANSI lumens of brightness and a native resolution of 1280 x 720. Compared to most budget projectors in its price range the image quality of this projector is quite high due to the higher resolution. Most budget projectors under $100 are only 480p. Unfortunately, like most budget projectors it has several trade offs over mainstream brands: it is not usable in the daylight and the fan is quite loud. If you’re going to be using a projector as a daily driver I recommend spending more money on something from Epson and Optima, however for the occasional movie night in a totally dark room this projector does the trick.

Build Quality

Included in the box is the projector itself, a 6-ft long power cable, a remote and an RGB input cable. Build quality between these cheap projectors is largely similar so if you’re comparing this to other options you won’t do better. It’s all plastic and kinda hollow feeling, though the plastic does fit together solidly. The legs don’t extend at all. Instead you get this little flap on the bottom as a very basic adjustment. The projector also does offer a slight tilt adjustment that’s only really useful if you’re hanging it upside down. If you’re going to have it right side up, use a small tripod and the tripod screw on the bottom.

Projection Quality

In terms of actual projection quality, there are a few things to keep in mind. First, you’ll need to use this in a pitch black room. Daytime use is basically a no go as any ambient light more or less drowns out the projection. But assuming you have a dark room this projector has decent picture quality overall. The increase in resolution versus other cheap projectors is pretty noticeable especially when it comes to things like browsing web pages with text.

The projector works surprisingly well for bright movies and content such as anime and cartoons. By default the colour settings are a way too overstated but with some adjustment the colours it can reproduce are accurate and detailed. Don’t be too heavy handed on any slider or it’ll severely wash out colours and detail. Dark footage like Game of Thrones or other dramas do not work as well as bright and colourful footage does, but are still watchable.

Audio Quality

There is a built in speaker that is actually relatively good for the price bracket. Now it’s not going to blow you away like the fan noise does but dialogue from it is clear. It just lacks punchy bass. For extended watching I would recommend an external speaker, but in a pinch this does the trick. Unfortunately, the headphone output on my projector was also a problem. The audio that comes out of the headphone jack is literally unusable, with a constant high pitched feedback in the background. The best option is to use the audio output on your source device instead.

Other Notes

All of the issues mentioned so far are relatively small and common at this price point. The flexibility and brightness are trade-offs of almost all budget projectors. But there is one thing that is not great about this projector: the fan noise. It is so darn loud. Using a headset or good speakers at a reasonable volume will drown it out, but this is about the maximum volume acceptable for a projector fan.

On a whole this is a basic projector. It turns on and displays images and that’s about it. In order to meet the $100 price point the C80 forgoes a few features: there is no wireless display. There’s only 1 HDMI port. The operating system has few settings.

Ideal projecting distance with this is between 6 and 8 feet. You can go further away but it’ll get too big and dim. There’s no zoom so you’re stuck moving the projector back and forward to get the size you want. As with other cheap projectors it can be tough to get the entire image in perfect focus but in the end the quality of projection will all come down to your specific room and how the projector is mounted.

Even a slight ambient light will drown out the projector. This projector is only for use in a totally dark room.


Overall, this is the budget projector to get if you care most about resolution, and I figure it’s one of the better options under $100. The image quality is a significant step up from most 480p projectors, and even though it lacks features like wireless display, on many other cheap projectors that’s just a gimmick anyways. Use it in a totally dark room and it does fine, especially considering the price.

  1. Hi, there are versions of this product out there with at least three different specs, using different groups of advertising slide images in each. I did see one say latest 2019 version.

    Are these different models from OEM that different trade brands sell, or identical but figures confused?

    A comparison between them would help?

    AUN type new claim 2200 lumens (scope 1800-3000 lumen), 200 Anxi (I guess might be ANSI) brightness.
    Contrast somewhere between 1000-2000 static and 10000 dynamic. 30 thousand hour lamp life. 60/64 watt power.

    The erisan, and some bevision ads, claim:

    2400 lumens, 240 ANSI, 2400 contrast (a bit convenient relationship of numbers).
    50,000 hours lamp life
    Max 50 watts power

    Now, the third major types (apart from advertisements for 1500 lumen vivibright, which is supposed to be 2200 lumen). Is:

    2800 ansi lumen (obviously a mistake, and not ANSI). 270 lux. (Is this really a ANSI figure?).
    2000-10,000 contrast.
    30,000 hour lap life.
    60 watts power.

    The differences can easily be explained by using different LCD panels and due efferent LEDs. Is f this is the case, the picture quality differences could be extreme. A good led is going to have a wide dynamic range rgb color peaks, leading to more pure color and brightness passing through the LCD for the same powered led (which means power consumption could be lower, if the led is not more inefficient, meaning its hard to tell by the numbers above). But a better LCD will let more brightness through, and with a good LCD color filter more pure color, but the more pure l, eventually that reduces actual brightness passing through, as it nocks off impure light. So, a wide color, but still high eye response, light source, like a laser, or lesser a osram led or quantum dot coated led, passing through a sharp like 90% pass through lcd panel with a matching wide color gamut filter, is going produce the best results. I think the new projectors we will be seeing, will get near this).

    So, the numbers above are not obvious. The Erisan could be a better setup, with the 2800 lumens version being a higher end product, or it maybe that that this 2800 might have been last years higher end version. It could be that the numbers are confused and the Erisan is better than the 2800, or that the AUN is in reality the same, or better tham the rest despite the numbers. Which would be really odd.

    Having looked at some samples the few Erisan reviews I have seen look better color, but was that better setup or newer phone/cameras jazzing up the colour. I’ve seen one sample from one of the others, with appalling washout, but did that person put brightness up to maximum? This asks another question, the claimed 2800 lumen variation, is it going look any good at that brightness at all? Proper reviews and test benching are needed to compare projectors again past projectors.

    1. I think that some sellers are just lying about the item and they are likely all the same, or very similar. Maybe there are some with the same body and different light sources in it but it would surprise me… A lot of sellers of cheap projectors overstate what their projectors are capable of in order to sell more to customers who don’t know better.
