As you know, the main mechanism of vape is to vaporize essential oils into smoke for users. Vape always has a coil (may-xo wire) that provides heat from the battery's electricity and cotton that acts as a conduit, absorbing just enough amount onto the coil to evaporate in each puff, and adding juice to the coil for the next puff. The burner will be the space designed for the coil and cotton to work. Different designs serve different purposes, today we will learn about RDA
- What is RDA: (Rebuildable dripping atomizers) are atomizers that have a dripping style (the type where the user pulls out the lid and immediately sees the wire and cotton, drops essential oil on the cotton, closes the lid, takes a few puffs until the cotton dries and there is no more essential oil, then you will have to pull out the lid to add more essential oil).
Identification features: RDA does not have a chamber to hold essential oils. The way to open an RDA is usually to pull the lid and you will see the cotton and wire immediately.
Advantages during use: easy to replace and use. Suitable for changing many different types of juice flavors. Spacious chamber space suitable for many types of coils, large and small.
Disadvantage during use: you will have to bring a juice bottle to add more essential oil after the cotton dries (after 4-5 puffs, maximum 8-10 puffs).
- What are the forms of RDA:
Classification by playing style:
Flavor play: technical characteristics of RDA types have small size and height, combined with details such as air hole design to direct the air from the bottom of the coil up, the cap (lid) has an inner surface that gradually curves towards the mouthpiece, helping the flavor to come out well, for example Hadaly, Notoy, Noname...
Usually this type is designed with a single coil, not focusing on the amount of smoke but on the flavor.
Smoke playing: technical specifications have large size, very wide chamber space for cotton coil. Large wire hole or clamp type to fit many wire sizes, usually smoke players will play coils with large cotton contact cross section. Horizontal air hole in the chamber to mix smoke, creating more smoke for the user.
Classification by design mechanism:
Very simple, there is a juice making mechanism called sqounk, this mechanism is an evolution of the first generation RDA. The only difference is that the RDA is optimized for the sqounk juice making mechanism.

Specifically, RDAs with squonk mechanism use a contact pin (with the squonk body) that is punched through a hole to pump juice from the bottom feed tank from the body of the machine up. Some manufacturers will include a regular contact pin so you can replace it when not using the squonk box body. At the same time, the design of the cotton chamber will be deeper to hold more cotton, which means holding more essential oil in each squeeze of the bottom feed tank. Divide the juice tray to divide the amount of essential oil pumped up evenly between the 2 coils.
