Overview

The Accell USB-C to HDMI Adapter (model U187B-005B) is an active adapter that connects USB Type-C devices to HDMI displays. It supports up to 4K UHD resolution at 60Hz, making it ideal for presentations, media playback, or extending your desktop. The adapter works with any host device that supports DisplayPort Alternate Mode over USB-C, including Thunderbolt 3 ports. Measuring just 6 inches (15 cm) in length, this ultra-portable adapter is easy to carry in a laptop bag. It draws power directly from the USB-C port (5V @ 160mA), so no external power supply is needed. The adapter is compatible with a wide range of devices, from MacBooks and Windows laptops to Android smartphones.

Connectivity & Compatibility

This adapter requires a USB-C port that supports DisplayPort Alternate Mode. Confirmed compatible devices include MacBook Pro (2016 and later), MacBook Air (2016 and later), Dell XPS 13, Chromebook Pixel 2015, LG G5, Samsung Galaxy S8/S8+, Lenovo ThinkPad T470/T480/X1 Carbon, and HP Spectre series. Thunderbolt 3 ports are fully supported. On the display side, any HDMI-equipped monitor, TV, or projector will work. The adapter supports HDMI 2.0, enabling 4K at 60Hz with smooth video playback. Note that devices with USB-C ports that do not support DisplayPort Alt Mode (e.g., charging-only ports) will not work with this adapter.

Product Info

The Accell U187B-005B is available through major online retailers like . It typically retails for around ¥11,000–¥12,000 and comes with a 2-year limited warranty. The package includes only the adapter itself; no drivers or additional cables are required. Positioned as a mid-range active adapter, it offers better signal integrity than passive alternatives, making it suitable for longer cable runs or demanding 4K/60Hz applications. The active circuitry ensures reliable performance even with less powerful host devices.

Best Use Cases

Laptop users needing an external monitor: If your laptop only has USB-C ports (e.g., MacBook, Dell XPS, Surface), this adapter lets you connect to an HDMI monitor or projector for presentations, coding, or media consumption. The 4K/60Hz support ensures crisp visuals. Smartphone or tablet users wanting big-screen output: Android devices with DisplayPort Alt Mode (like Samsung Galaxy S8 and later) can mirror or extend their screen to an HDMI TV. Great for watching movies or showing slideshows, but check device compatibility first. * Thunderbolt 3 PC owners: Since Thunderbolt 3 is electrically compatible with USB-C, this adapter works seamlessly. It's a cost-effective way to add an HDMI output to a Thunderbolt 3 laptop without buying a full dock. However, this adapter is not suitable for devices without DisplayPort Alt Mode support, and it cannot output 4K/60Hz to older HDMI 1.4 displays. For users who need multiple HDMI outputs or additional ports, a full USB-C hub might be a better choice.
