How to fill your vape pen?

Filling a vape pen is a vital skill for vaping. Without it, you will not be able to vape. This can be tricky as different devices are filled in different ways. But don’t worry, we’re here to guide you through what to do.

Filling a Closed System Vape Pen

A closed system vape pen uses cartridges readily filled with e-liquid. These cartridges are simply connected to the battery and then the vaping can begin. The cartridge acts as the mouthpiece, the heater and the tank all in one.

When the cartridge is finished with, remove it from the device, get rid of it and add a new one on. Cartridges unfortunately do not have as much of a wide range of flavours as normal e-liquid bottles, but new flavours are being released all the time.

Another issue with cartridges is they are not see-through, so you cannot see how much e-liquid is left in the bottle. To find out if the cartridge needs replacing, look out for a weaker hit. If you’re not getting the same throat hit or your flavour has faded, it’s time to get rid of it. If you keep vaping it after, you can risk burning the atomizer, resulting in an unpleasant taste.

Filling an Open System Vape Pen

An open system vape pen uses e-liquid bottles, that you fill your appliance with manually. They often use clearomizers, which are transparent, allowing you to see how much liquid is left.

Standard vape pens are filled by first removing the battery and the mouthpiece. Carefully squeeze the e-liquid down the sides of the tube, but make sure not to get any in the central tube, as this is the airflow and you will get e-liquid in your mouth. Most bottles come with a nozzle, helping you to be more precise and stopping you from pouring liquid on the atomiser or in the central tube.

Fill it up to your desired level, which, unless you want to mix flavours, is to the top. Be sure not to fill the tank past the internal tube, as this can lead to the e-liquid leaking or can even damage the device. Most starter kits have the maximum capacity labelled on the clearomizer to make sure you don’t pour in too much.

When you refill the vape pen, it is suggested that you do it over a paper towel, so it can easily be cleaned up. When you are refilling, it is also a good time to clean the mouthpiece, to keep giving you a smooth draw. You do this by placing a tissue in the back of the unscrewed mouthpiece, then blowing through it. It is advised that you replace the clearomizer after every 10 refills to ensure the best flavour and vapour.


Hopefully, this has helped you to understand how to fill a vape pen. Some vape pens can have different ways to fill. Some mods may have child protection, so you must go through an extra step. If you are unsure about how to fill your vape pen, be sure to consult your instructions. Happy Vaping!
