Product information

Description

The Dell USB-C Mobile Adapter DA300 is a compact 6‑in‑1 wired USB‑C adapter designed to connect laptops and ultrabooks to monitors, wired networks and USB peripherals. It provides video output up to 3840×2160, Gigabit Ethernet, and USB data connectivity via a single USB‑C host connection in a small, portable form factor.

Advantages

The adapter combines HDMI, DisplayPort, VGA, Gigabit Ethernet, USB‑C and USB‑A ports in one round, pocketable unit, enabling video, network and data connections without multiple dongles. It supports up to 4K at 60Hz on compatible hosts and offers SuperSpeed USB data transfer rates up to 10 Gbps when connected to a suitable USB‑C or Thunderbolt port. The retractable cable and compact design simplify storage and transport.

Suitable for

  • Connecting a laptop to an external monitor or projector (HDMI, DisplayPort or VGA)
  • Wired network access via Gigabit Ethernet for meetings or travel
  • Connecting USB peripherals such as external drives, mice or keyboards
  • Mobile professionals who need a small multiport adapter for office and travel

When it may not be suitable

Only one video output can be used at a time, so the adapter is not suitable for driving multiple independent displays simultaneously from a single connection. Also, full 4K at 60Hz and 10 Gbps USB speeds require a host port that supports DisplayPort Alt‑Mode 1.3 (or higher) and sufficient USB‑C/Thunderbolt power and bandwidth; on earlier or lower‑power USB‑C ports, video may be limited to 4K at 30Hz and USB data rates may be restricted to USB2.0 speeds.

Key specifications

  • Ports: HDMI, DisplayPort, VGA, Gigabit Ethernet (10/100/1000 Mbps), USB‑C downstream, USB‑A downstream
  • Video support: up to 3840×2160 (4K); up to 60Hz when host and display support required Alt‑Mode/HDMI standards
  • USB data: SuperSpeed up to 10 Gbps on supported host ports; fall back to lower USB speeds on limited ports
  • Network: Gigabit Ethernet
  • Host interface: USB‑C (wired)
  • Colour: Black
  • Weight: 0.08 kg

How to use

Plug the adapter into a USB‑C port on your laptop. Then connect a monitor or projector using HDMI, DisplayPort or VGA, and plug a network cable into the RJ‑45 port for wired connectivity. Attach USB peripherals to the USB‑C or USB‑A downstream ports as needed. The adapter is plug‑and‑play on supported operating systems; no external driver installation is generally required. If you need advanced Dell Business features (PXE Boot, Wake‑On‑LAN, MAC address pass‑through), pair the adapter with compatible Dell systems.

What to consider before purchase

  • Verify your laptop's USB‑C port supports DisplayPort Alt‑Mode 1.3 or higher for 4K@60Hz output
  • Check whether the host USB‑C port supplies sufficient bandwidth/power for 10 Gbps USB transfer rates
  • Only one video output can be active at a time
  • Compatibility: works with most Windows and macOS versions; check specific OS requirements for your system

Usage recommendations

For best results, connect the DA300 to a USB‑C or Thunderbolt port on a laptop that explicitly supports DisplayPort Alt‑Mode 1.3+ and higher power/bandwidth. Use HDMI or DisplayPort when you need 4K@60Hz, and connect peripherals to the downstream USB‑C/USB‑A ports according to the host's supported USB speed.
