A mini-projector is a device that will be of great help if you need to view and display graphic or video materials.
Types of mini-projectors
Devices, depending on their purpose, can be divided into:
- mini-projector for presentations - it is used for conducting lectures or trainings. The device proves to be indispensable when frequent changes of audience are necessary;
- mini-projectors for the house - they are used at home to watch your favorite movies;
- pocket mini-projector - a device of a small pocket size, similar to the size of an average smartphone . It can easily fit into a portfolio or in a jeans pocket, which makes its use especially attractive for business people who often make displacements in the nature of their activities. A projector connected to a mobile device allows you to view videos and photos in larger amounts than the screen of this device allows.
Advantages and disadvantages of mini-projector
Among the advantages of a mini-projector are:
- light weight - for a portable device it is 3-5 kg, and for an ultraportable device it is less than 1 kg;
- compact dimensions - the device does not take up much space, which makes it possible to store it with convenience;
- a sufficiently powerful battery that provides about three hours of continuous operation in an autonomous mode;
- convenience in moving and transporting.
At the same time, a mini projector for a laptop has some disadvantages compared to fixed devices, which include:
- less qualitative brightness of the image, which is explained by a relatively low indicator of the intensity of the light flux. Some devices are equipped with a powerful LED to achieve an output of 30 lumens at a resolution of 800x600. This allows you to receive images of bright quality, even in a dark environment. But this function affects the cost of the device and makes it much more expensive;
- limitation in the size of the screen format;
- lack of many functions that provide correction of image quality, resulting in a more blurred picture.

The capabilities of the device determine the presence of different connectors for connection to a computer or other equipment. In order for the device to be freely movable, there must be a wireless function.
The presence of a mini-projector usb-port for connecting a flash drive or built-in card reader will avoid the need for a complicated connection to a stationary device .
Many devices have a built-in audio system. The disadvantage of this function may be the weakness of sound when connected to more powerful repeaters.
In addition, some instruments are equipped with such auxiliary functions:
- A console that facilitates the use of a mini-projector;
- a special laser pointer - can serve as an additional tool for conducting lectures;
- protection from unauthorized use and theft;
- an option to capture an image to form an insert with a logo;
- the ability to display a text string on the screen.
It is recommended to pay attention when choosing a carrying bag for a mini-projector. It should be comfortable and protect the device from possible damage. An additional advantage will be the availability of a variety of pockets in which you can place accessories.
Thus, the mini-projector will be able to significantly help you when using in professional activities or to bring additional comfort when used at home.
