China leads the production of 100W GaN chargers, with Shenzhen factories like Wecent offering OEM/ODM solutions from 200pcs MOQ. These compact, high-efficiency chargers provide up to 100W PD for laptops and mobiles, multi-port configurations, global certifications (CE, FCC, RoHS), and custom branding—making them ideal for B2B wholesalers, suppliers, and global brands seeking reliable, scalable charging solutions.
What Is a 100W GaN Charger?
A 100W GaN charger uses Gallium Nitride semiconductors to deliver 40% smaller size, cooler operation, and 3x faster charging than traditional silicon chargers. Supporting PD 3.0, QC 4.0, and PPS, these chargers power laptops, smartphones, and tablets efficiently.
Shenzhen manufacturers excel in mass-producing multi-port (2C+2A) 100W units. Wecent specializes in dynamic power allocation—100W single-port or 65W+35W shared output—perfect for travel adapters and wholesale kits.
Specifications include 100–240V input, output profiles from 5V/3A to 20V/5A, and <0.3W no-load power. GaN II/III chips achieve 94% efficiency, minimizing energy loss. Wecent models seamlessly charge MacBook Pro, Dell XPS, and Samsung S-series devices.
How Do 100W GaN Chargers Compare to Silicon Ones?
100W GaN chargers are up to 50% smaller, run 20°C cooler, and charge 30% faster than silicon alternatives. They also outperform in density, heat management, and power-sharing flexibility.
China’s ecosystem supports automated SMT lines and integrated R&D. Wecent leverages local chip supply to offer 30% cost savings on wholesale GaN chargers.
