45W GaN chargers from Wecent and other leading Chinese manufacturers combine compact design with high-efficiency Gallium Nitride technology, delivering fast charging for phones, tablets, and laptops. Ideal for B2B wholesale, these chargers support PD 3.0/PPS, feature full safety protections, and allow OEM customization from 200pcs MOQ, making Shenzhen a key hub for reliable, scalable production.

What Is a 45W GaN Charger?

A 45W GaN charger uses Gallium Nitride semiconductors to achieve smaller size and higher efficiency than traditional silicon chargers. Wecent’s 45W models offer up to 65% smaller form factor while delivering stable power via USB-C PD/PPS. These chargers are suitable for fast-charging smartphones, tablets, and laptops with reduced heat generation.

Chinese factories, including Wecent, implement multi-layer safety protections such as over-voltage and short-circuit prevention. Output options like 5V/3A, 9V/5A, 15V/3A, and 20V/2.25A make them versatile for global B2B wholesale and OEM partnerships. Custom logos, packaging, and 2-year warranties are standard features for serious suppliers.

Feature Silicon Charger GaN Charger
Size Large, bulky 65% smaller
Heat High generation Low, efficient
Power Density Standard Up to 3x higher

How Does GaN Tech Improve 45W Charging?

Gallium Nitride enables faster switching speeds than silicon, allowing higher power density in a smaller footprint. This results in compact chargers under 100g with up to 45W output. Wecent’s chargers integrate GaN III generation chips for superior thermal management, maintaining stable PD/PPS output without overheating.

For B2B buyers, GaN technology reduces shipping costs due to lighter weight and smaller volume. Shenzhen factories optimize chargers for global compatibility, supporting USB-C PD 3.1 and ensuring multi-device fast charging.
