Rebuildable Dripping Tank Atomiser or RDTA. An RDTA is a combination between an RDA and a tank. It has a rebuildable deck on the top and a tank at the bottom. You would build on it in the same way as an RDA but with one difference. The end of your cotton would need to go into the tank at the bottom. There are holes for you to feed the cotton through into the bottom. As you vape it, the magic of science happens, and the juice is pulled up from your tank and into your coils. RDTA’s provide the taste of an RDA with the convenience of a tank, it’s a great in-between.
