Like in the picture. 510 inner threads are broken. I cant connect any 510 device. I can only use the outer threads.
@julopy that adapter uses 510 inner to connect to battery i think.
Adapter must use outer threads of battery and I must be able to connect 510 devices to other side of the adapter.
Does this adapter work? Does it's larger part fit to the outer thread?
801 to 510 Adapter
