Description

Turn your handheld gaming PC into a full desktop setup with the B3 Dock. The 4K@60Hz HDMI 2.0 output lets you mirror or extend your screen to any HDTV, monitor, or projector, delivering crystal-clear visuals for gaming, video calls, and presentations. A built-in 1000Mbps Gigabit Ethernet port provides a rock-steady internet connection, eliminating lag and ensuring smooth online play or work sessions. Three USB-A 3.0 ports give you fast access to peripherals such as keyboards, mice, external drives, or controllers, while the 100W USB-C power delivery keeps your Steam Deck or ROG Ally fully charged at full speed. Designed as a 6-in-1 solution, this dock consolidates power, video, networking, and peripheral connectivity into a single, compact station. Compatibility with both Valve Steam Deck and ASUS ROG Ally means you can switch devices without changing accessories. Note: the dock does not support the Steam Deck OLED 90Hz mode. Upgrade your portable console to a powerful workstation with the B3 Dock and enjoy a seamless, high-performance experience wherever you go.
