I bought the 808-510 adaptor from Vapor Kings so I could use my 808D1 battery with a 510 cartomizer. I am fairly certain I bought the right adapter- one end fits perfectly over the cone threading on my battery and the other end screws into the cartomizer nice and tight. But it's not working. It's as if something is not making contact all the way. I seem to remember reading somewhere that the pin inside the adapter might be adjustable so that it makes better contact between the battery and cartomizer. Has anyone tried this adjustment? If so, what tools did you use and how did you do it? Thanks so much for reading and helping me out; I really want to be able to expand beyond 808 cartomizers.
