What is a Vape Pen for E-liquid?

E-liquid vape pens, or e-cigarettes, are complete pen-style AIO kits that consist of a battery, a detachable vape tanks, and an atomizer coil. The atomizer coils will need to be replaced regularly depending on how much you vape. The tank can be refilled with any e-liquid you choose to bring you fantastic flavor.

Vape pens for e-liquid used to be the size of a pen but nowadays many tube mods are significantly larger due to higher battery capacity and have more functions to cater to advanced vapers. The vape pens are usually much easier to use than the complex box mods. They look more like cigarettes. Many smokers or new vapers opt for vape pens as their first e-cigarettes.

Notes: All the vape pens available in the UK are TPD compatible.

How to Choose the Best Vape Pen for you?

Vape pens come in a number of sizes and shapes and have plenty of functions and features. There are many factors need to be taken into account when picking up a vape pen that works best for you. For example, there is a tradeoff between size and battery life. The smaller vape pen will certainly compromise on battery. You should consider how you prefer to use the vape pen and what you will need it for.

Sub-Ohm Vape Pen for DTL Vape

The sub-ohm vape pens are higher powered devices for those who prefer the intense flavor and huge amount of cloud. They usually come in the shape of a tube and will be larger than regular vape pens to accommodate the high-capacity battery. The sub-ohm vape pens have higher power output and are fully functional. They have coils with a resistance below 1.0 Ohm and are vaped direct to lung. If you are a new vaper or looking for a first e-cigar, these are not recommended.

The sub-ohm vape pens should be used with higher VG e-liquid for huge vapor. I recommend a minimum of 70VG right up to 100VG. The downside is that they drain the e-liquid and battery faster with higher output.

Mouth to Lung (MTL) Vape

MTL is essentially the same as how most people smoke on a real cigarette. The vapor gets into your mouth then inhale into your throat or lungs. The MTL vape pens are generally smaller in size than the DTL devices. The wattage outputs for MTL vape pens are usually under 15W. They don’t require much power to generate huge clouds. Instead, flavor and nicotine hit are the key elements to delivering nicotine satisfaction.

There are 3 types of vape juice that are usually used with MTL vape pens: 50PG/50VG e-liquid, 40PG/60VG e-liquid, and nic salt.

How to Use a Vape Pen for E-liquid?

Most of the vape pens come with two parts, a battery mod, and an e-liquid tank. The battery is the main body that you hold and the tank includes a coil head for vaporizing. It is quite simple to use an e-liquid vape pen. If you struggle with using a vape pen for the first time, read the detailed guide carefully. This is a general tutorial that will work for most vape pens.
