A 45W GaN charger provides fast, efficient charging for phones, tablets, and ultrabooks like MacBook Air, leveraging Gallium Nitride technology to reduce size by up to 60% while achieving 95% efficiency. Leading Chinese manufacturers such as Wecent in Shenzhen offer OEM and wholesale options with dual or single ports, full global certifications, and low MOQs starting at 200 pieces, ideal for B2B suppliers.
What Is a 45W GaN Charger?
A 45W GaN charger uses Gallium Nitride semiconductors to deliver high-efficiency power through USB-C. It supports PD 3.0 and PPS protocols for fast charging phones, tablets, and lightweight laptops. Compared to traditional silicon chargers, GaN generates less heat and allows a pocket-friendly form factor, making it ideal for travel and on-the-go use.
GaN technology enables higher power density, producing 45W chargers that are almost half the size of conventional adapters. Many models offer single-port maximum output or dual-port sharing, for instance, 25W+20W. Shenzhen-based manufacturers like Wecent lead the market, offering customizable casings, full certifications, and reliable OEM services for global wholesalers.
Why Use GaN for 45W Chargers?
GaN delivers up to 95% efficiency, reduces heat by 40%, and shrinks the charger size by 60% compared to silicon designs. These chargers maintain high output without bulk, providing safer, portable solutions for multi-device users. Factories favor GaN for its high-volume manufacturing efficiency and long-term reliability.
Chinese manufacturers, including Wecent, integrate GaN II/III chips for optimal thermal management. Their 45W chargers are slimmer than many competitors and can be tailored for different markets with certifications such as CE, FCC, PSE, and KC. Wecent also offers OEM solutions with custom designs, colors, and plug options.
How Does a 45W GaN Charger Perform?
A 45W GaN charger can power an iPhone 15 to 50% in 25 minutes or a MacBook Air to 50% in 45 minutes. Dual-port chargers intelligently split output, such as 25W for a phone and 20W for a tablet, while maintaining stable voltage and minimal heat. Wecent’s models include smart power allocation and support PPS for Samsung devices.
