A Pico projector is a small, portable device that can project images and videos onto a surface, such as a wall or screen. These projectors are compact enough to fit in a pocket, making them convenient for on-the-go presentations or entertainment. They typically connect to various devices like smartphones, tablets, or laptops, allowing users to display content easily. Pico projectors use LED or laser technology to create bright and clear images, despite their small size. They are ideal for personal use, such as watching movies or sharing photos, and are increasingly popular in business settings for quick presentations without the need for bulky equipment.
