The Cthulhu 520 RBA V2 is a powerful rebuildable atomiser kit built for advanced vapers who demand control and versatility. Engineered by Cthulhu Mods, a trusted name in vaping innovation, this upgraded version introduces an enhanced chimney, refined single coil deck, and unprecedented airflow options perfect for direct-lung (DL) and restricted direct-lung (RDL) vapers using boro mods or AIO setups.

Enhanced Design & Performance

Upgraded Chimney and Build Deck

The upgraded chimney and single coil deck deliver improved flavour, airflow dynamics, and build flexibility. It's tailor-made for enthusiasts who value hands-on vaping.

Largest Airflow Range in a Boro RBA

With airflow options ranging from 0.8mm to 4.5mm, the Cthulhu 520 RBA V2 is the most adaptable boro RBA available. Whether you want a tight RDL draw or an open DL hit, this device can accommodate.

Advanced Engineering

CFD-Designed Airflow and Chimney

Utilising computational fluid dynamics (CFD) software, Cthulhu Mods has fine-tuned the chimney and airflow for maximum performance. This design reduces turbulence for a smoother, quieter vaping experience.

Versatile Coil Compatibility

The included PNP coil adapter allows use with Voopoo PNP, Vaporesso GTX, and VC Tech coils, giving vapers unmatched versatility. Whether you prefer rebuildables or stock coils, the 520 V2 accommodates both.
