Amazon Basics 4-in-1 USB-C Adapter HDMI Ethernet

The Amazon Basics 4‑in‑1 USB‑C Adapter converts a single USB‑C or Thunderbolt 3 port into HDMI, Gigabit Ethernet, USB 3.0 and a 100W PD passthrough charger for laptops and mobile devices.

This compact gray hub brings four essential ports to computers with a USB‑C or Thunderbolt 3 input. It streams high‑resolution video to an external display, adds wired network access, offers a fast USB 3.0 port for peripherals and supplies up to 100 watts of power delivery while using only a small portion of that power for its own operation. The adapter is lightweight and small enough to carry in a laptop bag while delivering the bandwidth needed for common productivity and media tasks.

How well does it handle video and displays?

The HDMI port supports high‑definition output up to 4K at 60Hz with 18 Gbps bandwidth and HDR compatibility, which is suitable for external monitors, TVs and projectors for crisp visuals and smooth motion. It works with laptops and devices that support video over USB‑C or Thunderbolt 3.

• 4K/60Hz HDMI output for sharp, smooth video
• 18 Gbps bandwidth and HDR support for richer color
• Compatible with TVs, monitors and projectors over HDMI

Can I charge my laptop while using the adapter?

Yes — the integrated USB‑C PD passthrough accepts up to 100 watts of power‑delivery charging. The adapter itself consumes about 8 watts, so most of the incoming power (up to approximately 92W) is forwarded to the host device, letting you run power‑hungry laptops and charge at full speed while using other ports.

• Supports up to 100W (20V/5A) PD input
• About 8W used by the adapter, remainder passed to host
• Use your laptop’s original USB‑C PD charger for best results

What data speeds and peripheral connections does it provide?

The hub includes a USB 3.0 Type‑A port and a USB‑C data port, each supporting up to 5 Gbps transfer speeds for external drives, keyboards, mice and other accessories. The USB 3.0 port also supplies downstream charging up to 7.5 watts for devices like phones or small accessories.

• USB 3.0 Type‑A: up to 5 Gbps data, 5V@1.5A downstream charging (7.5W)
• USB‑C data port: up to 5 Gbps for fast external storage access
• Plug and play with most modern operating systems—no extra drivers in most cases

Does it add reliable wired networking?

Yes — the built‑in Ethernet port provides a wired network connection when Wi‑Fi is weak or unavailable. This is useful for stable file transfers, low‑latency video calls and setups that require a predictable network connection.

• RJ‑45 Ethernet port for wired networking
• Works well for reliable streaming, downloads and conferencing
• Ideal as a backup or primary network option where Wi‑Fi is limited

Product dimensions are approximately 3.35 × 1.77 × 0.51 inches with an overall cable length near 17 inches, making the hub portable and easy to position on a desk. It is compatible with USB‑C and Thunderbolt 3 ports and comes backed by an Amazon Basics 1‑year limited warranty for basic peace of mind.

Who is this for? This multiport adapter fits laptop users, hybrid workers and travelers who need to add an external display, a wired network connection, a USB‑A accessory port and passthrough charging without carrying multiple dongles. It’s particularly useful for people who want a compact, plug‑and‑play way to expand a thin laptop’s connectivity in meetings, at home or on the road.
