USAMS CC279 65W 3-Port GaN Fast Charger Overview
The USAMS CC279 is a compact, multi-port GaN (Gallium Nitride) wall charger designed for efficient, high-speed charging of laptops, tablets, smartphones, and accessories. Launched around early 2023 as part of USAMS’ Sandru series (similar to the US-CC180/CC110 models), it leverages GaN technology for a smaller footprint, reduced heat, and faster power delivery compared to traditional silicon chargers. With two USB-C (PD) ports and one USB-A (QC) port, it supports simultaneous charging of up to three devices via intelligent power allocation (PPS protocol for Samsung/OnePlus). It’s UL/FCC/CE-certified for safety, making it a reliable travel companion. As of November 14, 2025, it’s popular for its balance of power and portability, available in EU/US/UK plug variants.
