What Are Pen-Style Vaporisers and How Do They Work?
Pen-style vaporisers are long, slim devices with a bigger battery and a refillable tank. You fill the tank with e-liquid and charge the battery. Most vape pens are activated by either a fire button or automatic inhale.
They sit between pod kits and box mods in terms of power. Vape pens usually offer:
- A battery that lasts several hours to a full day.
- A tank that holds more e-liquid than a pod.
- One simple fire button, so there is nothing tricky to learn.
- USB charging, so you can top up almost anywhere.
This style suits people who already know they enjoy vaping and want longer battery life without jumping straight to an advanced mod. It also gives you room to grow, since you can experiment with different tanks and coils as your taste develops.

What Are Box Mods and Who Are They For?
Box mods are larger, more powerful vapes with settings you can adjust, like wattage and airflow. They are built for experienced vapers who want full control over their vape.
Box mods usually come with:
- Higher battery capacity, often using external 18650 batteries.
- Adjustable wattage and temperature settings.
- Sub-ohm coils, built for big clouds and bold flavour.
- Swappable tanks, so you can change your setup easily.
Box mods work best with direct-to-lung (DTL) inhaling. This means you pull vapour straight into your lungs in one smooth breath, rather than holding it in your mouth first. This style needs higher VG e-liquid, thicker in texture, made for cloud production.
Box mods are not the easiest starting point. If you are brand new to vaping, start with a pod kit or vape pen first.
What Happened to Disposable Vapes in the UK?
Disposable, single-use vapes are now illegal to sell in the UK. The ban started on 1 June 2025 and covers every shop, online store, and market stall.
The ban exists for two main reasons:
- Waste: Millions of disposables are being thrown away every week, and their batteries are hard to recycle safely.
- Youth access: Cheap, colourful disposables made it too easy for under-18s to get hold of vapes.
Devices sold in the UK must no longer be single-use products. They must be rechargeable and/or designed for continued use through replaceable or refillable components. This implication changed the shape of the whole market, and a new type of device stepped in to fill the gap.
What Are Big Puff Bars and Are They a Legal Alternative?
Big puff bars are rechargeable, refillable devices built to look and feel like the old disposable bars. Unlike traditional disposables, these devices are reusable because they recharge and use refillable tanks or replaceable pods.
Big puff bars give you:
- The same simple, pocket-friendly shape as old disposables.
- A rechargeable battery, so nothing gets thrown away after one use.
- A refillable tank or pod, which saves money over time.
- Long-lasting flavour, since you top up with your favourite e-liquid.
If you liked the ease of disposables, a big puff bar is your closest legal match. You can find a strong lineup of these among our best vape kits, picked to suit UK vapers switching over from single-use devices.
