A vape pen is a slim, cylindrical device that heats e-liquid into a smooth, flavoured vapour. It is simple to use, gentle on the wallet and one of the most reassuring ways to begin your vaping journey. For many people making the switch from smoking, the short answer is yes, a vape pen is a sensible first choice. It will not suit everyone equally, though, so here is the honest picture to help you make an informed choice at your own pace.

What a vape pen actually is

A vape pen is roughly the size and shape of a chunky marker pen, which is where the name comes from. It has three main parts working together: a rechargeable battery in the body, a refillable tank that holds your e-liquid, and a coil inside that tank that warms the liquid into vapour. You draw on the mouthpiece, the coil heats up, and you breathe in vapour rather than smoke.

Most pen style vape devices are built around a mouth to lung draw, which closely mimics the sensation of drawing on a cigarette. That familiarity is a big part of why the vape pen remains such a popular beginner vape. There is very little to learn. You charge it, fill the tank with your chosen e-liquid, and away you go. Because the tank is refillable and the coils are replaceable, a vape pen tends to offer excellent value over time. Rather than replacing the whole device, you simply swap in a fresh coil and top up the tank, which keeps running costs sensible and is kinder to the environment.

It is worth saying clearly that vape pens are compliant, reusable devices. Single-use disposable vapes have been banned in the UK since June 2025, so a refillable pen is very much the way forward if you liked the ease of a disposable-style device. You can see the compliant options in our disposable vape alternatives collection.

Vape pen or pod kit: which suits you

The other name you will hear most often is the pod kit. A pod kit uses small pods that click into the device, and the coil is frequently built into the pod itself, so you replace the whole pod when it wears out. A vape pen, by contrast, usually separates the tank and coil, giving you a touch more flexibility and a slightly larger e-liquid capacity. Pens tend to be longer and thinner, while pod kits are shorter and slip more easily into a small pocket.

Neither is better in absolute terms. A vape pen tends to suit you if you are new to vaping, like a cigarette-style mouth to lung draw, and are happy to refill a tank and change a coil now and then. A pod kit may serve you better if you want the most discreet, pocketable device and would rather click in a pod than refill. If you would like to see the trade-offs side by side, our guide to the advantages of each vaping style walks through it in plain terms.

Choosing a vape pen you will be happy with

If a pen style vape sounds like your kind of device, a few simple checks will help. Look at the battery capacity, measured in mAh, where a larger number means longer between charges. Check that coils are easy to find and affordable, since you will replace one every week or two. A 2ml tank is the UK standard, and if you are moving away from cigarettes, confirm the device is set up for a mouth to lung draw. E-liquid strengths in the UK go up to 20mg/ml, and a balanced 50/50 liquid or a nicotine salt at a strength that suits you both pair nicely with a pen.
