USB-C Power Delivery 3.1 expands on PD 3.0 by adding an Extended Power Range (EPR). For travel, the 140W capability is the sweet spot, enough to power a MacBook Pro 16-inch while keeping the charger compact. Gallium Nitride (GaN) semiconductors allow these chargers to run cooler and smaller than traditional silicon-based designs. Wecent, with 15+ years in charger manufacturing, has extensive experience building GaN chargers from 20W to 240W, making them a trusted partner for high-wattage travel solutions.
