The KEFEYA S1 is a plug-and-play, versatile external, portable folding single-screen laptop splitter designed to enhance productivity by providing multi-screen mirroring or extended display capabilities. It allows for the quick setup of a personal mobile workstation, aiming to boost work efficiency by up to 50% and enable efficient multitasking.

Function Description:

The S1 serves as a laptop screen extender, offering an additional display for laptops. It supports a wide range of laptop shells, from 13 inches to 17.3 inches, making it suitable for various users including professionals, white-collar workers, gamers, stock traders, entrepreneurs, programmers, and students. Beyond laptops, the S1 also supports screen mirroring on select smartphones (such as Samsung and Huawei) and utilizes the smartphone's built-in desktop mode for audio-video transmission.

The device features an easy-to-use stand that clips onto the top of the laptop screen, ensuring a secure and non-slip attachment. Each screen of the S1 allows for independent adjustment of brightness, sound, contrast, and other parameters. It is equipped with both MINI HDMI and Type-C interfaces, eliminating the need for additional docking stations. For laptops with a full-featured Type-C port (which supports both signal and power supply), a single Type-C cable is sufficient for connection. Devices with an HDMI output interface (such as desktop hosts, mini PCs, set-top boxes, or game consoles) can also be directly connected, but the screen will require an external 5V/2A power supply to light up (a Type-C mobile phone charging cable can be used for this purpose).

A notable feature is the S1's ability to provide a complete 180-degree rotation on a single screen, allowing users to choose their optimal viewing angle for the best visual experience.
