Welcome to the forum! I moved this question over into its own topic so It’ll be easier for people to find in the future.
Specs for Wolf King charger are 84V, 1.5A with GX16-3P connector.
The Wolf King is a 72V scooter, meaning 72 V nominal and 84 V at max charge (see our battery voltage charts for more info).
In the U.S., VORO Motors and KREO Motors both carry the King so you might inquire if they sell (I couldn’t find on their site), otherwise if you are going generic, you should be able to get a charger/quick charger from Amazon or elsewhere with these specs:
