VENTION 140W 4-Port GaN Wall Charger (Black) - Power Delivery 3.1

Description

The VENTION 140W GaN wall charger is a centralised industrial-grade power unit, specifically configured for repair workshops, electronics laboratories, and B2B IT infrastructure management. Designed to replace multiple bulky power adapters, this ultra-high-density power supply unit integrates the latest generation fast-charging ecosystem. It allows for the simultaneous powering of up to four power-hungry devices, from workstation-type laptops to workshop smartphones and tablets.

In terms of electronic engineering, this charger leverages GaN (Gallium Nitride) technology. The use of this wide-bandgap semiconductor offers energy efficiency far superior to traditional silicon, reducing Joule effect losses and minimising internal thermal heating of the casing. This efficiency allows for a maximum power output of 140W via the Power Delivery 3.1 (EPR - Extended Power Range) protocol, capable of pushing a 28V/5A current through the main USB-C ports to charge a high-end laptop at its maximum nominal speed.

The device features an intelligent power distribution matrix managed by a dedicated microcontroller (MCU). This system continuously analyses the electrical signature and charging requirements of connected devices to dynamically and safely adjust the voltage and amperage delivered (fixed profiles and PPS mode). The black chassis is machined from high-strength flame-retardant polycarbonate (PC) polymer, complemented by multiple active protection circuits against overcurrent, overvoltage, short-circuits, and thermal anomalies.

Workshop Advice & Usage

To fully exploit the 140W power of this VENTION charger on your test benches, you must use an e-Mark certified USB-C to USB-C cable that supports the PD 3.1 EPR protocol (current supported up to 240W / 5A). Using a standard USB-C cable would structurally limit the power delivered to 60W (20V/3A) for safety. Also, explain to your customers that inserting or removing a second device causes a one-second micro-cut on all ports: this phenomenon is normal and corresponds to the algorithmic power distribution recalculation phase performed by the internal microcontroller.
