Cthulhu 520 Plus RBA Tank - ECIGONE

Cthulhu 520 Plus RBA Tank is a rethought design of the original 520 RBA created by the incredibly talented people at Cthulhu and manufactured using only the highest quality materials. With its newly designed chimney, a new polished finish on the internal chamber for better aesthetics and a variety of different airflow pins right out of the box, The 520 Plus RBA is guaranteed to cater for each individual vaper's precise needs whether they are a beginner or a knowledgeable seasoned vaper, This RBA has all grounds covered! 

Everything You Need In One!

With the 520 Plus RBA, Not only do you get the newly improved RBA itself, But you also get a variety of different extra’s including the Boro Tank itself which is incredibly easy to fill and two different bases. It also includes various airflow pins for MTL all the way to DL uses, A PnP Coil adapter, A Nautilus Coil adapter and a 510 adapter for use when wanting to build the RBA deck. Thanks to the various added extras, This helps to create a boro RBA and tank that not only appeals to advanced vapers, But one that can also be adapted for a more simpler use for beginner vapers too!

New Improved Design

The 520 Plus RBA has been designed to completely revitalise your AIO, With its ability to create a vast array of airflow styles thanks to the inclusion of 6 airflow pins in various sizes from 0.8mm and all the way up to 3.5mm. Furthermore, Using your RBA without an airflow pin will provide a massive 4.5mm under coil airflow to deliver a spectacularly open experience for direct to lung enthusiasts while still delivering the best possible flavour performance from your chosen e-liquid. Thanks to the newly designed domed chimney, This helps reduce the L-Shaped airflow bringing the user a much smoother and far quieter vaping experience than the previous variant.

Incredible Versatility 

With the sheer amount of extra added adapters, extra base for use with the tank and airflow pins, The 520 Plus RBA truly can cater to the widest variety of use preferences imaginable. Hobbyist vapers can enjoy the easy to use build deck of the RBA catering to various handmade coil diameters, And beginner vapers can explore two different coil types as they wish with both Voopoo’s incredible PnP selection as well as Aspires well known nautilus coil selection.
