What is a tank on a vape?

Vape tanks hold the e-liquid and allow it to soak into the wick which makes contact with the coil Tank & RDA. This means that when the vape is in use, the coil can heat up to vaporise the liquid absorbed by the wick. The vape tank continues to replenish the wick until the e-liquid needs to be replaced.

What is the best RDA or RTA?

1) RTA tank has a larger capacity to hold more e-liquid RDA. 2) Using RTA is much easier than RDA and is recommended for beginners. 3) Fewer drips are needed than in RDAs. RTA juice tanks are more convenient and save you from carrying the liquid bottle wherever you go.
