Overview

The j5create JCA175-EJ is a compact 4-in-1 USB-C multiport adapter designed for laptops and tablets with USB-C ports. It packs an HDMI output (up to 4K at 30Hz), a VGA output (up to 1920x1200 at 60Hz), a USB 3.0 Type-A port (5Gbps), and a USB-C Power Delivery pass-through port (up to 100W) into a tiny 40g body. It's ideal for professionals who need to connect to projectors or monitors on the go without carrying multiple dongles. The adapter supports plug-and-play with Windows, macOS, Chrome OS, and iPadOS, making it a versatile travel companion.

Connectivity & Compatibility

The adapter requires the host device to support DisplayPort Alt Mode over USB-C. It works with Windows, macOS, Chrome OS, and iPadOS, and is also compatible with Thunderbolt 3/4 ports. The HDMI and VGA outputs can work simultaneously in mirror mode, making it perfect for presentations where you want the same content on two displays. The USB 3.0 port enables high-speed data transfer up to 5Gbps, and the PD port allows you to charge your laptop while using all other ports. Note that the Apple USB SuperDrive is not supported due to manufacturer restrictions. Additionally, on M1 iPad Air/Pro, a USB device must be inserted into the adapter first for it to function correctly.

Product Info

Released around 2020, the JCA175-EJ remains widely available at a street price of roughly ¥5,400 (about $50 USD). It comes with a 2-year manufacturer warranty and local Japanese support via phone, email, and AI chat. The package includes the adapter, a quick-install guide, and a warranty card — no driver installation needed. It sits in the entry-to-mid-range segment, offering excellent value for users who need basic video output and charging expansion without breaking the bank. Compared to competitors like Anker or UGREEN, j5create differentiates with strong domestic support and a solid warranty.

Best Use Cases

This adapter is best suited for: Business travelers and presenters: The dual HDMI+VGA output covers most conference room displays. You can leave your bulky dock at home and just take this lightweight adapter. It's not ideal for extended desktop use since simultaneous output is mirror-only. Users with single-USB-C laptops: If your laptop only has one USB-C port (like many ultrabooks), the JCA175-EJ lets you charge and use peripherals simultaneously via that single port. Perfect for MacBook Air, Surface Pro, and similar devices. Budget-conscious shoppers: At around ¥5,400, it's a cost-effective way to add video and USB expansion. However, if you need 4K at 60Hz or have devices without DP Alt Mode, look for a different adapter. Users who prioritize portability: At 40g, this adapter is one of the lightest in its class, easily slipping into a laptop bag pocket.
