The S1 mobile LED projector is designed for your on-the-go life. At just 3cm (1.18 inches) tall and weighing 342g (0.75lbs), the S1 Mobile LED Projector is the perfect portable projector for mobile professionals that need to travel light, so you can take it with you wherever you go. Its built-in rechargeable 22Wh battery gives you up to 3 hours of cable-free projection time; it means you're free to set up the projector wherever you want without having to worry where the nearest power socket is. The S1 can also serve as a 6000mAh power bank to charge your mobile devices even when the S1 is off. With a best-in-class short-throw ratio, the S1 Mobile LED Projector displays a 41-inch diagonal projection just one meter away from the screen -this lets you turn any large flat vertical surface into a display, and makes it perfect for presentations in confined spaces. The S1 has a mercury-free, 200 lumens LED light source that provides 100% NTSC colour saturation and full colour RGB projections for uncompromised visuals. The S1's LED light source helps you save on costly maintenance fees. With a 30,000 hour lifespan, you can use the S1 for eight hours a day for up to 10 years without needing a replacement lamp. The S1 has an instant On/Off capability as there is no need for the LED light source to warm up or cool down. This means your ideas, your videos, or your pictures can be shared in a jiffy.
