Vention USB-C to USB 3.0*3 + RJ45 HUB 0.15M Black

Vention USB-C to USB 3.0*3 + RJ45 HUB 0.15M Black

Wi-Fi drops mid-call. A large file transfer stalls at 60%. A video conference stutters at the exact moment it should not. These are not hardware failures. They are the predictable result of relying on wireless for work that needs a wired connection. The Vention TGPBB USB-C Gigabit Ethernet hub fixes this with one plug. Wired internet appears. Three USB-A ports appear. The laptop stays connected to everything at once.

Wired Network and Peripherals From One Port

The TGPBB converts a single USB-C port into three USB 3.0 ports, a Gigabit RJ45 Ethernet port, and a Micro-B power input. Five connections from one USB-C plug. All run simultaneously.

This is a connectivity-first hub. It solves the network problem and the port shortage in one device. No separate Ethernet adapter. No USB-A dongle. One compact hub handles both.

Gigabit Ethernet — 10/100/1000 Mbps, Wired and Stable

The RTL8153 chip drives the RJ45 port at up to 1000 Mbps full-duplex. It supports auto-MDI/X crossover. It runs on IPv4 and IPv6 networks. Connect a standard RJ45 cable — the hub negotiates the network speed automatically.

Wired connections do not drop during large file transfers. They do not slow when neighbouring devices compete for bandwidth. They do not introduce the latency that makes video calls feel slightly off. Gigabit Ethernet is simply faster and more stable than Wi-Fi in almost every real-world condition.

5Gbps Across Three USB 3.0 Ports

The VL815 hub chip drives three USB-A ports at up to 5Gbps each. Connect a keyboard, a mouse, and a flash drive simultaneously. Transfer files to an external drive at full USB 3.0 speed. All three ports run at the same time. Older USB 2.0 and USB 1.1 devices connect at their own native speeds — the hub handles both without adjustment.

Micro-B Power Input for High-Demand Peripherals

The Micro-B port accepts 5V/2A supplemental power. Use it when connecting power-hungry devices — an external hard drive, a high-draw peripheral — that exceed what the laptop’s USB-C bus can supply alone. It is optional for most setups. It is essential for a few.

Where the TGPBB Gets the Work Done

The Remote Worker With an Unstable Wi-Fi Connection

A home network shared with streaming, gaming, and other devices creates congestion. A USB-C laptop with no Ethernet port has no way out of that congestion — without this hub. Plug the TGPBB in, connect an Ethernet cable, and the laptop leaves the Wi-Fi entirely. Video calls stabilise. File transfers complete. The connection no longer depends on who else is using the router.

The IT Professional Configuring Devices On-Site

Connecting a laptop to a wired network switch, a USB keyboard, and a diagnostic flash drive simultaneously is a routine on-site task. The TGPBB handles all three from one USB-C port. The Gigabit connection supports the full network speeds of most corporate infrastructure. Plug-and-play operation means no driver installation on the target machine — the hub works immediately on any compatible OS.

The Business Traveller in a Hotel or Conference Venue

Hotels and conference centres often provide wired Ethernet in rooms and meeting spaces. A USB-C-only laptop cannot access it without an adapter. The TGPBB fits in a jacket pocket. It connects the laptop to wired Ethernet while keeping USB peripherals — a presentation remote, a mouse, a flash drive — simultaneously available. Full product specifications are confirmed on the official Vention TGPBB product page.

The Student on a Campus Wired Network

University campus networks often deliver faster, more reliable speeds over Ethernet than Wi-Fi — especially in dense residential areas. A student with a USB-C MacBook or ultrabook connects to the wired network via the TGPBB while keeping a mouse and a USB drive running on the remaining ports. The CE, FCC, and RoHS-certified build meets any institutional compliance requirement.
