JEMDO Switch 2 HDMI Dock 4K 144Hz 48Gbps HDMI

This portable HDMI dock cable for the Switch 2 turns a slim USB-C lead into a travel-friendly TV adapter that supports high-frame-rate gameplay and simultaneous charging. It is aimed at players who want 4K visuals and reliable power while using hotel or living-room screens, and it supports 100 W Power Delivery for longer sessions according to the manufacturer.

Key Points

This cable uses HDMI 2.1 bandwidth to carry Ultra-HD 4K at up to 144 Hz and 5.1-channel audio, helping to maintain smooth motion and detailed images during fast-paced games. The plug-and-play design works with the Switch 2 (versions below V21.0.0), the 2017 Switch and Switch OLED, and other USB-C devices that support video output, making it useful both for travel and at home. The construction focuses on signal integrity with triple shielding and gold-plated connectors to reduce interference and resist wear during repeated use. Note that it is not compatible with the Switch Lite and higher Switch 2 firmware versions may need additional firmware information from the manufacturer.

Technical Specifications

• Cable length: 6.6 ft / 2 m
• HDMI standard: HDMI 2.1, 48 Gbps

Usage Recommendations

For best results connect to a USB-C 3.2 charger or an OEM Nintendo power supply that supports the required PD profile. Allow a few seconds for the TV and console to negotiate HDR settings the same way you would when using an original dock. When using handheld PCs such as Steam Deck or ROG Ally, check the device’s supported power profiles and select the appropriate charger to benefit from the 65W or 100W options.

Advantages

The lightweight, compact cord replaces a bulky dock with a much smaller footprint and lower weight, making it convenient for commuters and travellers. Heat dissipation is improved by an aluminium shell and the cable is lab-tested for durability up to 10,000 bends, which reduces the chance of signal dropouts during extended play. According to the manufacturer, the internal chipset and Dynamic HDR support help maintain stable video output with minimal flicker or black-screen interruptions.
