All About Clearomizers

Apollo offers a large selection of clearomizers, and with so many options, it can be confusing to decide on the one that is right for you. Almost each and every model produces a distinct vapor sensation based on its components. Our advice is to try out a few different models and find the one that suits your preferences. Follow this helpful guide to learn more about the differences and benefits of each model.

What is Threading?

Similar to the threading on a screw, all e-cig batteries and cartridges have threading used to screw them onto each other. In order to be compatible, the threading types need to match between the batteries and the cartridges. Some common threadings include 510, eGo, 906, 108 and 808D. 510 and eGo tend to be the most common. A standard eGo battery is compatible with both 510 and eGo threading, which is why you’ll often see them listed together. 906, 108, and 808D refer to the smaller e-cig batteries that more closely resemble actual cigarettes.

What are Coil Heads?

Coil heads are what house the wick and atomizer in clearomizers. Essentially, it’s the part that heats up and turns your e-liquid into vapor. Coil heads need to be replaced periodically(about every 2 to 3 weeks), so a clearomizer with replaceable heads is more cost effective. Your coil head needs to be replaced when your vapor starts getting an unpleasant burnt/spicy flavor and/or the liquid inside turns dramatically darker. Coil heads come in different resistances, measured in ohms. The lower the resistance of your coil head, the hotter the coil will get. This temperature effects how the vapor feels when you inhale. Everyone has their own preferences, so it’s best to test out different resistances to find what you like best.

Top Coil vs Bottom Coil

The location of the wick and coil plays a role in the feel of the vapor and the performance of the clearomizer. Bottom Coil clearomizers have the wick and coil located at the base of the tank. This location keeps the wick submerged in e-liquid and saturated at all times, resulting in a smoother vapor feel, and allows you to get every drop of e-liquid in the tank. Top Coil clearomizers have their wick and coil located towards the top of the tank. This location results in a stronger throat hit, and can also make it difficult for the wick to stay saturated when your tank gets low on e-liquid.
