Ease of Use


The Good

  • Real 720p image quality
  • Slight keystone adjustment
  • Simplistic user interface
  • Decent colour and contrast in dark rooms

The Bad

  • Not usable with any ambient light
  • Very loud fan
  • Headphone 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.
