V3 is the updated glass adapter for the Tempest V1 and V2, designed for hands-free use with the iSpire Wand.

The new, shorter cup design is more efficient, resulting in better heating and reduced battery usage. The plastic V2 adapter is still slightly more efficient, however the glass allows for improved visibility of the visual indicator. 

14 mm inner diameter. We recommend using it with the Wand Stand (sold separately).
