Charger plugs licensed in Hong Kong and Europe are all made of British tripods (three feet on each side), which is your kind. You can buy it at the hardware store. Or you can go to the n-machine monopoly to buy it. But the price is very expensive. If you charge it regularly. You can go to the hardware store and buy a small socket at will. There is such an interface inside. It is not too late. This is the small socket I bought. For example, MOMAX's USB multifunctional suit and other small things. A that can be used for conversion.
