Overview

The j5create JCD388-EJ is a ultra-slim USB-C mini dock that adds six ports to any USB-C laptop in a single plug-and-go package. Measuring just 11mm thick and weighing 47g, its aluminum unibody design feels right at home next to a MacBook. You get two USB 3.0 Type-A ports, one USB-C port with Power Delivery 60W and data, plus separate SD and microSD card slots. It supports DisplayPort Alt Mode for external monitor output without drivers. Whether you're at a desk or on the go, this dock covers the most common expansion needs without adding bulk.

Connectivity & Compatibility

The host interface is a fixed USB-C male connector that plugs directly into your laptop's USB-C port. Compatible with Windows, macOS, and ChromeOS devices. Works well with MacBook Air/Pro, Dell XPS, and iPad Pro. Two USB 3.0 Type-A ports transfer data at up to 5Gbps, ideal for mice, keyboards, and flash drives. The USB-C port supports Power Delivery 3.0 at up to 60W, charging your laptop while simultaneously transferring data. SD and microSD slots are UHS-I compliant, handling cards up to 2TB. Video output via DisplayPort Alt Mode — no driver installation needed.

Product Info

Released around 2020, the JCD388-EJ remains widely available at a very affordable price point (around ¥4,600). It sits firmly in the entry-to-mid-range segment, offering a practical 6-in-1 port selection at a price that's hard to beat. The dock comes with a 2-year manufacturer warranty and no accessories beyond the unit itself. Purchase is straightforward via major online retailers. Its market position is clear: deliver the essential ports in the smallest possible footprint. If you don't need Thunderbolt 4 speeds or 100W charging, this dock covers 90% of daily scenarios with zero fuss.

Best Use Cases

MacBook Air/Pro users: The slim design matches Apple's aesthetic perfectly. Two USB-A ports let you connect legacy peripherals without separate adapters. Not ideal for those needing Thunderbolt 3/4 speeds. Mobile workers and travelers: At 47g, it's barely noticeable in a bag. Pass-through PD 60W charging lets you charge your laptop through the dock, reducing cable clutter. However, laptops requiring 100W charging will charge slower. Photographers and content creators: Built-in SD/microSD reader makes offloading photos from cameras quick and easy. UHS-I speeds are adequate for most stills but won't saturate UHS-II cards. iPad Pro users: With a USB-C iPad, you can connect external storage, a wired mouse, and import photos from SD cards simultaneously. Check iPadOS version compatibility for specific features.
