Yes, pico projectors are legit. They are small and portable projector modules that can be integrated into mobile devices or used as accessories for mobile workers. While they may not be powerful enough for large screens, they are popular for home entertainment and can project a larger image than a laptop when streaming movies, TV shows, or sports. Pico projectors use DLP or LED technology and do not rely on traditional bulbs, making them more energy-efficient. However, the brightness may be a drawback as it is dependent on the power supply. Overall, pico projectors offer a convenient and compact solution for on-the-go projection needs.
