Verdict

The Asus Zenbeam S2 is a palm-sized portable LED projector featuring a 720p (1280 x 720) native resolution, 500 lumens of brightness, and 100% NTSC colour space coverage. Weighing just 497g, it utilizes a short-throw lens to project images up to 120 inches from only 3 metres away. Its main advantages include a built-in 6000mAh battery that provides up to 3.5 hours of operation and doubles as a power bank, rapid 3-second autofocus, 2D keystone correction, and versatile connectivity via USB-C and HDMI. On the downside, the 720p resolution is lower than Full HD standards, and its 500-lumen brightness may struggle in rooms with significant ambient light.
