Asus has quietly launched a new a-bean 100W GaN charger in China. Now available for about 179 yuan ($25), it features a compact design and can charge multiple devices at once.
The new charger uses a 3C+1A port layout offering three USB-C ports and one USB-A port. Asus says the charger is built around GaN (gallium nitride) technology, which allows it to deliver high power output while keeping the overall size relatively small.
According to the official specifications, the a-bean 100W charger measures 75 x 61 x 29mm and weighs around 211 grams. It also features foldable wall prongs, making it easier to carry in a backpack or travel bag. The product is available in multiple color combinations, including Cloud White + Graphite Gray, Cool Black + Fluorescent Green, and Cool Black + Space Gray.
Up to 100W charging from two USB-C ports
The charger’s two main USB-C ports, labeled USB-C1 and USB-C2, can each provide up to 100W of power when used individually. The third USB-C port supports up to 20W, while the USB-A port can output up to 22.5W using the SCP protocol or 18W through Qualcomm Quick Charge.
Asus has also included support for a wide range of fast-charging standards, including USB Power Delivery (PD), PPS, QC, SCP, FCP, QFC, and PE.
Like most modern multi-port chargers, the maximum output changes depending on how many ports are in use. When both high-speed USB-C ports are connected, the charger splits the power between 60W and 30W. Pairing USB-C1 with USB-C3 delivers 60W + 20W, while using USB-C1 and the USB-A port gives 60W + 22.5W.
For users charging three devices at once, Asus offers several power allocation modes. For example, using USB-C1, USB-C2, and USB-C3 together provides 45W + 30W + 20W, while connecting USB-C1, USB-C2, and USB-A results in 45W + 30W + 22.5W output.
When all four ports are active, the charger distributes power at 45W through USB-C1, 30W through USB-C2, and a shared 20W for USB-C3 and the USB-A port. This setup should be enough to fast-charge a laptop while also topping up a phone, wireless earbuds, and another accessory.
