The only eGo threaded clearos I’ve seen that work with the Volt Spinner are S.I.’s T3 and the Kanger T2. If you want to use the 510 threaded F16 carto/tank system on a Volt Spinner, you will need an 808 to 510 adapter. A short cone will cover the eGo threads but not the adapter.
IMHO, adapters are a temporary solution at best. You’re better off in the long run to use a juice delivery device that is designed to be used with the battery you’re using. If you really want to try a tank system on a Spinner, you can get an 808 threaded carto/tank system from a different vendor to use with the Volt Spinner, or you can get a 510 threaded Vision Spinner for the F16 system.
