27W GaN Multi-Voltage USB-C Power Supply: 5.1V 5A Optimized for Raspberry Pi 5

Product Overview

The 27W GaN USB-C Power Adapter is a precision-engineered, high-efficiency power solution designed for the modern era of single-board computing and mobile technology. By integrating advanced Gallium Nitride (GaN) semiconductors, this unit achieves a significant reduction in physical footprint while delivering a robust 5.1V 5A output—the critical requirement for the Raspberry Pi 5 to unlock its full peripheral performance.

Beyond its specialized support for the Pi 5, this adapter features a multi-voltage Power Delivery (PD) controller, making it a truly universal travel companion. It intelligently switches between 5V, 9V, 12V, and 15V profiles to provide optimal charging for flagship smartphones, premium tablets, and industrial IoT modules. The fanless, ultra-compact design ensures cool and silent operation, even under sustained maximum load.
