GaN (gallium nitride) chargers dominate new product launches. The material handles higher voltages and switching frequencies than silicon, so chargers shrink while staying cool.
Size and efficiency
For the same 65W output, a GaN design is typically 40% smaller and runs more efficiently, wasting less energy as heat. That means lighter travel chargers and slimmer product designs.
Multi-port intelligence
Our BK-W002 GaN II charger packs 2 USB-C and 2 USB-A ports into a palm-sized body with 100W total output and smart power allocation across ports.
Should your brand switch?
For premium retail SKUs, GaN is now expected. For cost-driven promotional items, silicon designs still win on price. As an OEM partner we build both, and can also mix — GaN chargers bundled with braided cables for gift sets.
