Kanger sure has hit the spot with their SubTank-concept. Here's a replacement RBA-base for the Subtank Mini and Plus.
One of the things that makes the SubTanks stand out is the option of building your own coil with the special RBA (Rebuildable Atomizer) base. This spare base can either replace a broken one or give you the ability to switch between different coil-builds for more diversity.
It even comes with a coil pre-mounted, so all you need to do is to ad wicking-material (cotton is recommended).
See if you can make a better coil than Kangers own pre-made coils.
Purchase is for: 1 x Mini RBA base for the Kanger Subtank Mini and Subtank Plus (works on both models).
*RBA base does NOT fit the Kanger Subtank or the Subtank Nano.
