This is a step by step guide to building and installing the RBA coil on a SMOK RPM 4 pod.
SMOK RBA coil comes with its own kit including the base, coil and cotton. Compatible coils can also be used depending on the resistance of the coil.
This RBA is incredibly handy for people who prefer hanging on to be the same coil base and takes little money and effort to rewick it.
Some RPM 4 Pods which are made for The RPM coils may not function with the RBA coil base properly. That is why I have also demonstrated what to do if such happens.
