A thread adapter allows you to use an atomizer or cartomizer with a battery of a different model. For example: Our 901 to [510] adapter allows you to use a DSE901 battery with a 510 atomizer or cartomizer. The first number in the adapter name represents the battery model and the second set of numbers represents the atomizer model.
