If you go on their official website, they don’t offer much of an explanation as to how it functions.
At its core, the JUUL pods contain a 1 mm coil containing 5 spaced wraps. It clocked in at 1.7 Ohms, which leads us to believe they are using 38-gauge Titanium, rather than Kanthal. The coil is attached to a gold-plated base, which creates contact with the battery when it’s inserted into the device.
The outer shell and mouthpiece, that also functions as a top cap, is made of plastic. Inside of the coil is a thin piece of silica, that wicks juice to the coil. The e-liquid inside contains your typical PG and VG, flavorings. The nicotine inside the juice is what separates the JUUL from your typical e-cigarette.
JUUL uses salt-based nicotine to deliver that intense throat hit that its users come to know and love. Another reason why these pods are so effective is because they contain 50 mg of nicotine. Many people misread the 5% on the package, but if you’re vaping on 6 mg, that’s equivalent to 0.6%.
When you take a puff, the coil is activated. It heats up and creates vapor which travels through a tiny metal rod, located in the center of the pod. With each puff, the vapor reaches the mouthpiece and is inhaled. No, it’s not magic, it’s just regular vaping, except that it contains a ton of that salt-based Nic.
