Users of the ASUS S1 short throw projector vouch for the product’s amazing features at a great price. Let’s put that to the test, as we review this short throw projector and look at its good and bad features.
One of the first things that you will probably notice is its size. This projector from electronics company ASUS is designed to conveniently fit in your pocket. Aside from the benefit of portability, let’s look into the other features of the ASUS S1 short throw projector.
ASUS S1 Short Throw Projector Overview
- Quality imaging on the go, ideal for use in the office or a home cinema
- Large, clear display provides 41” display when placed 1 meter from the screen
- Ultra-portable: measures 110.5mm x 30.7mm x 102mm
- Three hours of battery life

Throw and Zoom
Despite its miniature size, the ASUS S1 short throw projector produces huge images. It has the ability to project images as huge as 41” when it’s placed about a meter from a screen or wall. At a throw distance of 0.6 m – 2.4 m, the image size can range from 64 cm – 254 cm.
Compared to other short throw projectors, though, the throw and picture size of the ASUS S1 short throw projector may fall a bit short.
Image quality is surprisingly good for a projector that can fit in your palm. The color balance is excellent with definitive neutral grays at varying levels from black and white in all predefined image modes. It delivers vibrant, eye-catching color in all modes.
When used to present documents such as PowerPoint slides, the projector creates images with good detail. The black text on white was readable at 7.5 points, but you may encounter a minor soft-focus effect.
In terms of video quality, the device is limited to its native standard resolution (854×480). Its aspect ratio of 16:9 lets it take full advantage of the resolution to be used with widescreen video. The colors are within an acceptable range, but they also tend to be flat when you reduce the contrast ratio.
The shadow detail is remarkable, showing only a small hint of posterization in scenes that tend to cause that problem.
Although the manufacturer’s description says that it delivers 200 lumens brightness, the actual level of brightness may be lower than that. Setting it at Theater mode, the brightness becomes 127 lumens. This is bright enough for a 30” to 35” image in moderate ambient light, though.
However, because of its low lumens-brightness, it is best recommended to use in low lighting condition.
When using battery power, the brightness drops to 108 lumens in Presentation mode and about 71 lumens for the low power Battery mode. As a result, the brightness may be suitable for 20”-25” image for long viewing sessions in ambient light.
The ASUS S1 short throw projector is made from Advanced DLP Technology that allows at least 30,000-hour LED lifespan.
The ASUS S1 short throw projector has limited connectivity options:
- Signal Input: HDMI, MHL
- Audio Output: Earphone out
- USB Port: 1 x Type A port (used for charging only)
If you want to connect your iPhone/iPad to the projector, you would need to purchase the optional Lightning Digital AV Adapter from Apple. For Android devices, you may purchase a specific MHL separately.
This is definitely the best feature of the ASUS S1 short throw projector. It can easily be kept inside your pocket as you would your mobile phones. It weighs barely a pound and can comfortably fit in the palm of your hand.
Accessories and Other Features
One of the prime features of the ASUS S1 short throw projector is that it has a high capacity power bank at 6000mAh. You can connect your mobile devices even if the ASUS S1 is off.
It has a built-in SonicMaster speaker in which the audio quality is fair enough. The 2W mono speaker offers good sound quality and volume for a small room. However, if you want to increase the audio quality, use an external audio system.
The ASUS S1 short throw projector also comes with a power adapter, USB cable, and a carrying case.
- Projects a 41-inch display when placed 1 meter from the screen
- Ultra-lightweight and portable
- Conveniently priced
- Built-in battery
- May show scaling or rainbow artifacts
- Limited connection choices: you can only use image sources that can connect to an HDMI port.
- No zoom
The ASUS S1 short throw projector is an amazing choice for people with limited budget but still desire an exemplary viewing experience. Although the competition may have a similar pocket-type projector with higher lumens rating, they may not be as portable as the ASUS S1.
Despite its limitations – especially in terms of picture size and connectivity options – the ASUS S1 short throw projector can still provide a balance of image quality, brightness, portability, sound quality, and price.
