Aspire K3 Vape Tank

The Aspire K3 Vape Tank is a straightforward mouth-to-lung (MTL) clearomiser built for consistency, ease of use, and dependable flavour. Originally designed as part of Aspire’s K3 Starter Kit, it also works seamlessly with a wide range of vape devices thanks to its standard 510 connection.

With a 2ml e-liquid capacity and fixed airflow, the K3 Tank delivers a tight, cigarette-style draw that suits new vapers and experienced users who prefer a traditional inhale. Its uncomplicated design removes unnecessary adjustments and focuses on delivering smooth vapour, clean flavour, and predictable performance with every refill.

The tank comes pre-installed with Aspire’s proven 1.8Ω Nautilus BVC coil, known for long lifespan and efficient wicking when used with high-PG or 50/50 e-liquids. Replacement coils are widely available, making the K3 an easy tank to maintain long term.

Designed for Simple, Consistent Vaping

Fixed Airflow for a Traditional Draw

The Aspire K3 Tank uses a fixed airflow system that creates a consistently tight MTL inhale. This design is ideal for those transitioning from smoking, offering a familiar draw without requiring airflow adjustments.

Nautilus BVC Coil Compatibility

At the heart of the K3 Tank is Aspire’s Nautilus BVC coil platform. These coils are engineered to produce clean flavour while maintaining efficient liquid consumption. The included 1.8Ω coil works best with e-liquids containing 50% PG or higher, delivering a smooth throat hit and controlled vapour output.

Bottom-Fill Convenience

Refilling the Aspire K3 is quick and straightforward. Simply unscrew the base of the tank to access the fill ports, top up with your chosen e-liquid, and reassemble. A series of internal seals help reduce leaking when the tank is correctly assembled.

Available in stainless steel or black, the design remains clean and understated, making it suitable for a wide variety of devices and setups.
