Description

StarTech DKT31CHPD3 USB C Multiport Adapter

Overview

The StarTech DKT31CHPD3 is a compact USB-C multiport adapter designed to expand your laptop's connectivity for demanding professional workflows. It enables you to connect to an external display, peripherals, and charge your host device simultaneously, making it ideal for mobile professionals, content creators, and anyone needing to connect multiple devices to a single USB-C port. The DKT31CHPD3 supports high-resolution video output and high-speed data transfer, ensuring efficient operation in environments requiring robust peripheral support.

Compatibility

This adapter is compatible with any USB-C host device that supports DisplayPort Alternate Mode (DP Alt Mode) and USB Power Delivery 3.0. This includes most modern laptops and tablets from major manufacturers such as Dell, HP, Lenovo, Apple MacBook, and Microsoft Surface. It supports 16:9 aspect ratio displays up to 4096x2160 at 60Hz and 21:9 aspect ratio displays up to 3440x1440 at 60Hz. Ensure your host device's USB-C port supports video output and Power Delivery for full functionality.

Installation Notes

The adapter connects via its integrated 10-inch (25cm) USB-C cable. For optimal performance and to enable 100W Power Delivery pass-through, connect a USB-C power adapter (sold separately) to the adapter's USB-C PD port. The maximum power output to the host device is limited by the connected power adapter and the host's charging capabilities. Operating temperature range is 0 to 50°C (32 to 122°F), with storage temperatures from -20 to 70°C (-4 to 158°F). Humidity tolerance is 0% to 95% RH (non-condensing).
