The Yaber K300s uses a traditional lamp-based light source rather than laser, with a rated lamp life of 20,000 hours in eco mode. It includes a built-in battery offering up to 2.5 hours of untethered use, and a dedicated smartphone app is available for added convenience. In terms of physical dimensions, the unit measures 289 mm wide, 223 mm deep, and 84 mm tall, with a weight of 1800 g, making it a moderately compact option for a projector in this class.
The Yaber K300s outputs at a native 1080p resolution with a brightness of 1000 ANSI lumens, and can project an image up to 120″ in size with a minimum throw distance of just 0.16 m, allowing for large images even in tighter spaces. Focus is handled via a motorized mechanism for straightforward adjustments. On the HDR side, the projector does not support HDR10, HDR10+, or HLG, so high dynamic range content will be displayed without those enhancements.
The Yaber K300s covers wireless connectivity through Wi-Fi, Bluetooth, AirPlay, Chromecast built-in, and Miracast, giving users a broad range of options for streaming content from phones, tablets, and laptops without cables. On the wired side, it provides one HDMI port, two USB ports, and one RJ45 ethernet port for a stable network connection. VGA, DVI, and S/PDIF output are not included.
The Yaber K300s includes a built-in smart TV platform alongside stereo speakers rated at 2 x 15W with Dolby Atmos support, and a 3.5 mm headset jack for connecting external audio. It comes with a remote control and supports voice commands for hands-free operation, while a sleep timer adds everyday convenience. Neither vertical nor horizontal lens shift is available, and there is no external memory slot. The projector does not support lens shift in either direction, but overall usability is aided by the included smart TV functionality and the broad set of audio and control features on offer.
