This article covers USB Type-C 7-port HUB JCH377 by j5create.

Overview

The j5create USB Type-C 7-port HUB JCH377 is a compact expansion hub that adds seven USB 3.0 (5Gbps) ports to any USB-C equipped laptop, tablet, or desktop. One dedicated port supports Battery Charging 1.2 (up to 2.4A) for fast-charging smartphones and tablets while the other ports handle data transfer. The aluminum enclosure is both durable and heat-dissipating, and the hub can operate in bus-powered or self-powered mode via the included DC adapter (5V/4A). This hub is particularly useful for MacBook and Ultrabook owners who need to connect legacy USB-A peripherals, external drives, or charging cables through a single USB-C port. A USB-C to USB-A adapter is bundled for flexibility.

Connectivity & Compatibility

Product Info

  • Release: Originally launched around 2016 (still widely available) - Price range: Approximately ¥8,000 ( Japan, as of July 2026) - Warranty: 2 years (manufacturer) - Accessories: DC adapter (5V/4A), USB-C to USB-A adapter, manual - Where to buy: Japan, electronics retailers, online stores In terms of market positioning, this hub sits at the entry-to-mid level. It offers a straightforward expansion solution without extra video or networking features, but its 7-port count and fast-charging support make it a strong value choice for users who primarily need USB-A expansion.

Best Use Cases

  • MacBook / Ultrabook owners: If your laptop only has USB-C ports, this hub lets you connect a mouse, keyboard, external SSD, and other USB-A devices simultaneously through a single cable. Ideal for desk setups where you don't need video output. - Smartphone / tablet users: The dedicated fast-charging port can charge an iPhone or Android device at full speed while other ports handle data transfers or syncs. Keep in mind: you cannot charge the host laptop through the hub – the USB-C port is data-only. - Desktop PC power users: Place the hub on your desk for easy front-access USB ports. For power-hungry devices (external hard drives, etc.), connect the DC adapter to ensure stable operation. - Not for: Anyone needing HDMI, DisplayPort, Ethernet, or card reader functionality. Consider a multi-function docking station instead.
