There are two types of e-liquids or e-liquids that can be used in refillable disposable e-cigarettes: propylene glycol (PG) and vegetable glycerin (VG) vapor.

Using the wrong e-liquid can lead to burnt-out coils or leaky cartridges. You may also experience discomfort or a burning sensation in your throat after vaping.

If you are a vaper who is more interested in the vapor experience, the VG ratio should be above 70%. When used with e-cigarettes over 20 watts, the smoke will be thicker and more flavorful.

For smokers who prefer a throat hit, choose an e-cigarette with adjustable gears.

You don’t have enough e-cigarette liquid. The lower the amount of e-cigarette liquid remaining, the longer the device’s core is in contact with the coil.

When this happens, the wick dries out and overheats, creating a dry burn when pulled. If left untreated, dry firing can turn into burning.

Priming is the process of applying oil or e-liquid (used in e-cigarettes) to the coil or wick of an e-cigarette.

This heats up the e-cigarette and converts the e-liquid into vapor correctly.

However, if you don’t give the coil enough time or saturation, you will experience a dry or burning sensation.

For most e-cigarettes, you only need to oil the coil the first time you use it. However, continuous use of e-cigarettes can cause this problem.
