Best Single Coil RTA 2020 

RTA stands for Rebuildable Tank Atomizer, which is a tank system with one or more rebuildable coils. In general, an RTA comes with a build deck, a chimney that connects the build deck to the top cap of the atomizer, a glass tank, and a drip tip. Most of the RTAs on the market now comes with either a single coil deck or a dual-coil deck. We call an RTA with a single coil deck the single coil RTA and the tank with a dual-coil deck the dual coil RTA.

So what are the differences between a single-coil RTA and a dual coil RTA?

Compared with dual coil RTAs, single-coil RTAs tend to consume less battery power, fewer e-liquids and requires less expertise to rebuild thanks to their much simpler design. So if you want an RTA that is easy to build coils and can save your e-juices, a single coil RTA will be your best choice.
