[Gifts for Kids]: Home theater projectors use diffuse reflection imaging technology to protect children's eyes. Mini projectors are a must-have for kids who love watching cartoons and videos, and are very popular with children. When viewed from a distance with a projector, it can project up to 100 inches (recommended 14-100 inches), keeping kids away from mobile phones and tablets, and protecting their eyes. [Functional Screen Mirroring]: The outdoor projector measures only 4.3*1.85 inches / 110mm*47mm and weighs about 0.5LB, making it as small as a milk carton. Despite its compact size, it boasts powerful screen mirroring capabilities for iOS and Android phones. Tablets can also connect using their charging cables, eliminating the need for separate adapter cables. [HD Resolution]: The portable projector features a new light path design and a high-refraction lens, offering 8000L brightness and a 3000:1 contrast ratio. With a lamp life of 30,000 hours, a projection distance of 0.6-4.0m / 2.0-13.1ft, and a projection size of 14-100 inches, it delivers superior visuals and flexibility in projection space. [Built-in Speaker]: The projector includes a built-in 4Ω2W speaker with clear sound, low noise, and high performance, allowing you to immerse yourself in movies while catering to home and outdoor cinema needs, weddings, teaching, and artistic creation. You can also connect headphones and external speakers via the 3.5mm audio jack for a personal viewing experience or a group gathering. [Power Bank Support]: The home theater projector supports mobile power for on-the-go movie watching. While it can be powered by a wall adapter (no built-in battery), it can also be charged via a phone charger, car charger, or power bank through its micro-USB port (must support 5V/2.5A), enabling enjoyment anywhere, anytime.
