27W GaN Dedicated AC/DC Power Supply: 5.1V 5A High-Efficiency Solution for Raspberry Pi 5

Product Overview

The 27W GaN USB-C Power Adapter is a next-generation power solution specifically engineered for the high-performance ecosystem of the Raspberry Pi 5. By leveraging advanced Gallium Nitride (GaN) semiconductors, this unit achieves up to 91% efficiency, significantly outperforming traditional silicon-based adapters. It delivers a robust and sustained 5.1V 5A output—a critical requirement for the Pi 5 to unlock its full 1.6A downstream USB power allocation.

The ultra-compact, travel-ready design does not compromise on power integrity. The GaN-driven architecture minimizes internal heat generation, allowing for a fanless, cool-to-the-touch operation even during sustained 25.5W heavy-load delivery. Whether used for industrial edge computing, media servers, or professional DIY projects, this adapter provides the rock-solid electrical stability needed for mission-critical 24/7 operation.
