Every single-flavour Ingot 9000 uses the same hardware: Rated for up to 9000 puffs (usage dependent), a 22ml pre-filled tank, a 2350mAh battery that is not rechargeable, a mesh coil, inhale activation and a smart LED for battery and e-liquid. That figure comes from the manufacturer. The number you get changes with how long each puff is and how you draw. It is not a promise of 9000 puffs.
Strawberry Coconut Watermelon layers jammy strawberry, a coconut-cream middle and watermelon on the way out. Coconut is what sets it apart from Strawberry Watermelon: creamier, slower, and less splashy. Leave it if you want a single fruit note or a strong icy finish.
