Overview

The USB-C HDMI 3-in-1 Adapter is a compact, travel-friendly accessory that turns a single USB Type-C port into three essential connections: HDMI video output, USB 3.0 data transfer, and USB-C Power Delivery charging. Measuring just 8×3.5×1.5 cm, it slips easily into a laptop bag or pocket, making it an ideal companion for business trips, remote work, or everyday use at home. This adapter supports 4K resolution at 30Hz via HDMI, 5Gbps data speeds through its USB 3.0 port, and up to 60W of PD charging—enough to power a MacBook Pro while you work. It requires no drivers or software; simply plug it into any USB-C device and start using it immediately. Compatibility spans iPhone 15/16/17 series, iPads with USB-C, Android phones, MacBooks, and Windows laptops, making it a versatile solution for almost any modern device.

This adapter is positioned as an entry-level to mid-range solution for users who need basic expansion without breaking the bank. Priced around ¥2,800, it offers a practical combination of 4K video, USB 3.0 data, and 60W PD charging—features typically found in more expensive docks.

Best Use Cases

Frequent Travelers: Business professionals who need to connect their laptop to hotel TVs for presentations or entertainment will appreciate the compact size and all-in-one functionality. The adapter eliminates the need to carry separate HDMI cables, USB hubs, and chargers. However, if you require multiple USB ports or a longer cable, you may need additional accessories. Tablet Users Wanting External Displays: iPad or Android tablet owners can easily mirror their screen to a larger monitor for online classes, video calls, or creative work. The PD port keeps the tablet charged during use. Note that some tablets may have limitations on power delivery direction, so check your device specifications beforehand. Budget-Conscious Users Expanding USB-C Capabilities: If you find full docking stations too expensive but still need basic expansion, this adapter is a cost-effective alternative. It covers the three most common needs—video, data, and charging—in one small package. However, it only has one USB 3.0 port, so users who need to connect multiple USB devices simultaneously should consider a separate USB hub. iPhone 15/16/17 Owners: With the switch to USB-C, iPhone users can now output video to an external display while charging. This adapter makes it easy to watch movies on a TV or give presentations from your phone. Be aware that iPhone video output is limited to screen mirroring (no desktop mode like Samsung DeX), and the adapter is not compatible with iPhone 16e/17e/iPhone Air models.
