My rp2, charging has a problem, through some videos, I know his part number, 18275dc. I am in China, I have asked a lot of people, and I can’t get it. I am very entangled. . Very tangled, I don't want to go after the sale, I will spend a lot of tolls and maintenance costs (450 Hong Kong dollars to repair usb). . . Because of this little thing, I need to run from the mainland to overseas. I don't want to do this. I want to buy parts to find someone to help repair.
