According to the information I have learned, the charging port of the armrest can support fast charging, which adopts a Type-C interface and a USB-A interface, in which the Type-C interface supports a maximum of 15W charging power, while the USB-A interface supports a maximum of 18W charging power. Therefore, the charging port of the armrest can support fast charging, but the specific charging power will be limited by the device itself.
The charging port of Rongfang armrest supports fast charging, and the maximum output power is 18W. However, it should be noted that to use fast charge, you need to use a charger and data cable that support fast charge. At the same time, overcharging and long charging should also be avoided when charging to protect battery life.
