Asus has quietly introduced the a-bean 100W GaN charger in China, now available for approximately 179 yuan ($25).
The charger features a compact design with a 3C+1A port layout, offering three USB-C ports and one USB-A port.
Built with gallium nitride (GaN) technology, the device delivers high power output while maintaining a small footprint.
It measures 75 x 61 x 29mm and weighs around 211 grams.
Foldable wall prongs make it easy to carry in a backpack or travel bag.
The a-bean 100W charger is available in multiple color combinations: Cloud White + Graphite Gray, Cool Black + Fluorescent Green, and Cool Black + Space Gray.
Charging Capabilities and Power Distribution
The two main USB-C ports, labeled USB-C1 and USB-C2, can each provide up to 100W when used individually.
The third USB-C port supports up to 20W, while the USB-A port outputs up to 22.5W via SCP protocol or 18W through Qualcomm Quick Charge.
Asus has included support for USB Power Delivery (PD), PPS, QC, SCP, FCP, QFC, and PE fast-charging standards.
When both high-speed USB-C ports are used simultaneously, the charger splits power between 60W and 30W.
Pairing USB-C1 with USB-C3 delivers 60W + 20W, while USB-C1 and USB-A gives 60W + 22.5W.
For three-device charging, using USB-C1, USB-C2, and USB-C3 together provides 45W + 30W + 20W. Connecting USB-C1, USB-C2, and USB-A results in 45W + 30W + 22.5W.
When all four ports are active, the charger distributes 45W through USB-C1, 30W through USB-C2, and a shared 20W for USB-C3 and USB-A.
This setup can fast-charge a laptop while topping up a phone, wireless earbuds, and another accessory.
