Battery Adapter ego - 510
This adapter allows you to use eGo atomizers/Clearomizers with a 510 threaded "MOD" device.
May be needed with some MOD/APV batteries to allow you to use an atomizer or cartomizer with a battery of a different model.
Made from a solid piece of steel with a rubber isolated inner core, it will last a lifetime if used correctly - do not over tighten!
