ROG Bulwark DG300 | 7-in-1Dock | Connectivity

Enjoy seamless connectivity and simplicity with the ROG Bulwark Dock, a 7-in-1 dock supporting 100W USB-C charging, 10Gbps file transfer, and HDMI 2.1

USB 3.2 Gen2 Type-A | (10Gbps/BC1.2 5V/1.5A)

While USB Type-C is incredibly convenient, we know that tons of your favorite peripherals are natively USB Type-A. The ROG Bulwark Dock is equipped with a built-in 5V/1.5A power module, offering a stable 7.5W output that's optimized for the charging needs of smartphones and portable devices.

USB 3.2 Gen2 Type-A | (10Gbps 5V/0.9A)

With 10Gbps data transfer speed and 4.5W output, these ports ensure high-speed connectivity for your mouse, keyboard, or other essential devices-making it perfect for streamlined, travel-friendly setups.

Ethernet

A Gigabit Ethernet port eliminates the need for Wi-Fi when docked, for a faster, more stable connection.

HDMI 2.1

The ROG Bulwark Dock boasts an HDMI 2.1 port capable of delivering up to 4K at 144Hz or 8K at 30Hz, giving you the flexibility to game at high refresh rates, create content at high resolutions, or anything in between. With support for VRR (Variable Refresh Rate), the DG300 ensures seamless synchronization between your ROG Ally and external display - eliminating screen tearing and stuttering for a smooth, immersive gaming experience.

Downstream Port | For device output USB 3.2 Gen2 Type-C

Designed for high-performance handhelds like the ROG Ally, the Bulwark Dock supports up to 140W of input from an external charger-keeping your device powered during extended sessions. 10Gbps data transfer offers support for your USB drives and essential peripherals with ease, allowing you take your setup to the next level wherever life takes you.

Upstream Port | For system input USB 3.2 Gen2 Type-C

One port to rule them all - plug, play, and power up with USB Type-C. Upstream, the ROG Bulwark offers 10Gbps file transfers, enabling seamless sharing of large files and projects or games. The Bulwark Dock supports high resolution displays, allowing you to easily extend your laptop, handheld, or smartphone display to a second screen for an immersive visual experience. Up to 100W of Power Delivery allows the ROG Bulwark Dock to intelligently adjust and meet the power demands of your connected device.

3.5mm Combo Jack

A 3.5mm audio combo jack offers a one-plug solution to all of your audio needs.

Seamless Compatibility

The ROG Bulwark Dock is designed to pair your phone, gaming handhelds, and laptops with monitors, TVs, mice, keyboards, and any other peripheral you can think of. One cable, infinite possibilities.

Bold ROG styling adorns the ROG Bulwark Dock, with a fully illuminated ROG "Fearless Eye" logo.

This unique futuristic look makes the ROG Bulwark Dock a symbol of the cyber-metropolitan subculture. Built with a dystopian gamer style, it delivers an immersive aesthetic at the bleeding edge of design and tech.

With full control of its RGB lighting, these cyberpunk details transform your setup into a bold showcase of style and performance.

The transparent design on the flip cover blends gritty urban realism with cutting-edge tech. The ROG Bulwark Dock oozes an industrial, nostalgic vibe that feels both vintage and futuristic.
