The short answer is yes. However, some older RBAs have less than stellar insulators that can melt with the additional hear that subohm vaping produces. Additionally, the airflow on some older RBAs will not work at tge higher heat, but that's subjective... Make sure the insulators are good and go for it.Assuming one has a regulated mod that can handle it, is it possible to build a sub ohm coil in a standard rba? Or a normal coil in a sub ohm rba?
Thanks.
