According to a report from Chinese tech site IT Home, the major smartphone manufacturers are planning to unveil chargers based on Gallium Nitride (GaN) technology this year.
Xiaomi released its GaN-based charger last week and the charger employs a USB-C interface and is capable of delivering a 50W wired fast charge to the Xiaomi M10 Pro’s 4,780mAh battery, filling it to 100% in 45 minutes.
Currently, the fastest smartphone charger available from Apple can provide 18W wired charging, while Samsung offers 45W Adaptive Fast Charging and Huawei’s SuperCharge supports 40W charging.
According to GaN ideal , Gallium Nitride is a semiconductor that is commonly used in LEDs and Blu-ray disc readers.
What makes GaN ideal for battery chargers is its wider bandgap of 3.4 eV, compared to the 1.12 eV bandgap of silicon.
