Rebuildable Atomizers (RBA) and Mods Tutorial
Rebuildable atomizers and mods are huge topics. Let’s take a quick look at the basics!
Rebuildable Mods have two core sections. The lower part, the case that holds the battery, is the mod, and the top part where the coil is located is the Re-Buildable Atomizer (RBA). We’ll take a glimpse at two types of mods, the mechanical and the VV/VW, and three types of atomizers, the Genesis (Top Fed), Bottom Fed, and Dripper. Drippers are also referred to as the RDA. It stands for Re-Buildable Dripping Atomizer. Genesis atomizers commonly use a stainless steel mesh that’s rolled into a tube and torched to use as a wick. The standard build for the other atomizers use silica or ekowool as the wick, with ekowool being more robust. All atomizers currently use nichrome or kanthal as a resistance wire and Kanthal is more robust. One reason for torching is to burn off any manufacturing residue. These materials are used in many home and industrial applications, heating and ventilation systems, appliances like toasters, coffee pots and irons. Something that stands out with the drippers (RDA) is that they do not have a tank. Instead, you would just add a few drops of e-juice between drags. Drippers have fewer problems with wicking since you drip e-juice directly on top of the coil. And you can even switch flavors.
Resistance and Power
A factor in resistance is the length of the wire. Basically, adding more wraps lengthens the wire and therefore, it increases the resistance. Resistances that are less than 1 ohm is known as sub-ohm. Resistance is important because it affects the power. It’s represented with the equation Power = Voltage2 / Resistance. For example, if you’re getting 3.0V from the battery and the resistance is 1 ohm, the power will be 9W. When the resistance goes up, power will decrease, when it goes down, power will increase. Power affects vapor volume, temperature and flavor.
Mechanical and Variable Mods
Variable mods allow you to adjust the voltage or power up and down. Using the same equation from earlier, you can see how it’s related. You can adjust the voltage which will directly affect the power, or you can just set the power to a desired wattage.
Variable mods also have a protection cicuit against shorts and most will not work will low resistances, so you cannot use it for sub-ohm vaping.
Mechanical mods are basically a hollow tube with a switch. There is no circuitry in the device. However, since there is no protection circuit, you can build anything you want and it will still work. That’s why mechanical mods are excellent for sub-ohm vaping. Sub-ohm vaping can be dangerous if you do not know what you’re doing. The battery could potentially explode. It’s not recommended for new vapers, so do research about before starting.
The IMR Batteries are not your standard rechargeable batteries. The IMR’s are supposed to have a safer chemistry. They come in button top of flat top. The number on top is the battery capacity, and the lower number is the physical size of the battery.
