This is referring to an atomizer that allows the user to build and install the coil and wicking material themselves, rather than buying and replacing coil heads that contain prebuilt coils like one would do with a tank.
RDA (Rebuildable Dripping Atomizer)
A rebuildable atomizer style that requires you to drip liquid directly onto your coil and continue to do so as your wicking material dries out during vaping.
RDTA (Rebuildable Dripping Tank Atomizer)
This is essentially an RDA, but with a reservoir that holds juice located underneath the coil. The tank allows the user to vape for a longer period of time than with an RDA before needing to drip more juice onto the coil.
RTA (Rebuildable Tank Atomizer)
An RTA is a rebuildable atomizer with a juice reservoir located above or underneath the coil. It has the convenience of a tank, in that it can hold a decent amount of juice, but it allows the user to build and install their own coils, giving enthusiasts the best of both worlds.
The natural resistance of a coil, measured in ohms (Ω). As a general rule, higher resistance coils (1.0Ω +) will run at lower power levels, while lower resistance coils (0.15Ω) will run at a higher power level. Coils below 1.0Ω are commonly referred to as sub-ohm coils.
When excess juice in the coil isn't completely vaporized and instead heats up, then spits out of the drip tip and into your mouth. Among other things, this is a symptom of flooding.
This term refers to any coil or coil head that reads under 1.0Ω . Vaping with sub-ohm coils requires more power and vaporizes more juice at a time than coils over 1.0Ω .
A tank is the component of your vape set up that holds your coil or coil head and is surrounded by a chamber that holds e-liquid. A drip tip extends from the top from which you inhale and a connector protrudes from the base of the tank, which you screw into your device.
Temperature control is a method of vaping in which you control the exact temperature that you coil heats up to, rather than the wattage or voltage. Temperature control isn't supported on all devices and will not work with kanthal coils, so you will have to make sure that you are using Stainless Steel, NI 200, or Titanium coils and that your device is capable of temperature control.
Vape is a bit tricky as it can be used as either a noun or an verb. When used as a noun, it simply describes any device used to vaporize eLiquid, whether it be a pod system or a dual-battery mod with an RDA attached. An example sentence would be: “I went online and ended up ordered yet another vape last night and now I have more vapes than I can realistically use.” When used as a verb, it describes the action of inhaling vapor from an electronic cigarette of some kind. An example sentence would be: “I'm going to go outside and vape for a few minutes since it isn't socially acceptable or legal to chuck clouds in a restaurant.”
This is a common way to measure the power level that a device will fire at. Nearly every mod made in the last few years uses wattage as its default power adjustment mode. Increasing the wattage will result in more power going through the coil and decreasing the wattage will result in the opposite.
A wick's purpose is to feed eliquid to the coil, where the eliquid is then vaporized. The most commonly used wicking materials are cotton, wood pulp, and ceramic. In a pre-built coil head, wicking material is already installed and there are typically windows cut into the coil head that allow juice to travel into the wicking material.
