i have an akai apc mini and a led lamp atached to my chuwi via usb hub with ethernet adaper wich makes it drain the battery even when its pluged. Is there a way to use a 3A adapter or something?
Use a powered external usb hub. This way the usb devices don’t use the chuwi’s power because they have a separate power supply. (There are powered usb hub + ethernet adapter combos too, they are similar to yours but they have a circular power socket for external power supply)
