The mini projector is lightweight, compact and easy to carry. It's a handy presentation guide wherever you are. In projection mode, the projector turns on in seconds and you can project from a laptop, tablet, smartphone, or use HDMI, USB or a card reader. You can even project without a wired connection using the app. The advantage of the mini projector is Texas Instruments technology, which offers sharper and higher quality images with a projection area of up to 120 ". Another advantage is the Auto Keystone Correction function, which automatically adjusts the angle of the picture at ± 40 ° deviations. The mini projector is made of high quality materials and a thin aluminum case provides protection against mechanical damage. The projector is equipped with a built-in Li-ion eco-friendly battery with a 4000 mAh capacity, which means it will last up to 3 hours to project continuously.
