SQUONK TANKS Squonking has made a big return this year, combining the best of all worlds by combining the flavour of RDAs and RDTAs with the ease of a bottom-fed squeeze bottle.We have controlled, complete mechanical, and safe mechanical modifications to choose from.Complete mechanical mods (mech mods) are not recommended for beginners since they need a detailed understanding of Ohms Law, battery protection, and stable coil construction techniques.Squonking is possible for any RDA or RDTA that has a BF (bottom fed) pin.
