In addition, taking into account the situation of outdoor use, it is best to have a built-in battery, otherwise there is no electricity outdoors, and it will not be used.
2. The main thing is to meet our entertainment and movie watching needs, then the projection effect must be the main one, and the brightness (lumens) and contrast should be moderate;
Mini projectors generally do not have a very long projection distance, and are mainly used for personal use at home, so the lumen is generally about one or two hundred, because the higher the lumen, the more expensive it is, and the higher the brightness is, the eyes are prone to fatigue. If the brightness is too high, the fineness of the picture will be lost.
3. It is convenient to watch movies. Now more and more mini projectors have built-in Android modules, and you can directly connect to wifi to watch blockbuster movies and live TV broadcasts. It is also equipped with USB, HDMI and other interfaces, which is convenient to read the U disk and connect to the computer.
