Just like shopping for a proper pair of shoes for a special occasion, there is also a need for you to know how to choose a proper tank to satisfy your vaping experience. After evolving for many years, VOOPOO has designed mickle of tanks, including Uforce series, Rune RDA, Pericles RDA, Rimfire RTA etc. Do you actually know the difference between RDA & RTA? Let’s find out. What is an RDA? RDA (Rebuildable Dripping Atomizer) — an RBA with a deck with posts to anchor the coils and provide the electrical connections to the battery (mod) that heats the coils. The deck is covered with a cap (an outer shell) that screws on with threading or slides on with o-rings. RDAs have no tank section to hold e-liquid. They’re designed for e-liquid to be dripped from a bottle, drop by drop, directly onto the coils and/or wicks (usually after removing the cap, which is then replaced after dripping). Sometimes the decks have a well under the coils that holds a small amount of e-liquid, usually less than 1ml. A commonly held opinion in the vaping community is that RDAs as a class produce purer and more intense flavor than any other method of vaporizing. Thus, RDAs represent the gold standard against which all other types of atomizers are measured. (Pericles RDA) What is an RTA? RTA (Rebuildable Tank Atomizer) — a rebuildable atomizer (RBA) with a deck that has posted and is covered by a sealed metal chamber cap, around which is a tank reservoir for holding e-liquid. The chamber cap connects to a chimney that directs vapor to the drip tip. Gravity and pressure automatically force e-liquid in the tank down around the chamber cap and then up through slots or channels on the outer circumference of the deck. The wick ends are placed in these channels. As e-liquid saturates the wick, it is delivered to the coils to be vaporized. The difference between an RDA and an RTA is the tank. There’s no manual dripping with an RTA. (Rimfire RTA) All in all, all the innovative structures aim at bringing better vaping experience to you. which one is your wish to get?
