RTA (Rebuildable Tank Atomizer) - a tank system with a rebuildable coil. You fill it up and vape until the liquid is exhausted and then fill again. RTAs tend to be harder to build because they are assembled with multiple parts. Nevertheless, RTAs are still popular with those prepared to invest some learning time. Many vapers swear by the flavor production that they can get from an RTA. Check out the newest RTA’s by companies such as HellVape today!
