I’m sorry, but I’m not familiar with a device or product called a “flum” that would require charging. It’s possible that the term “flum” may not be widely recognized or that it refers to a relatively new or niche product that I don’t have information about in my database.
To provide you with instructions on how to charge a “flum,” I would need more specific information about the device or product you’re referring to. If you can provide additional details or clarify what a “flum” is, I’d be happy to assist you further.
