Features

The Caliburn G4 pod kit is designed to be easy and practical for daily vaping. It supports both mouth-to-lung (MTL) and restricted direct-to-lung (RDTL) styles, so you can choose the draw that suits you best. The 1300mAh battery gives you plenty of power for a full day of use, and the USB-C charging means it tops up quickly – usually in less than an hour.

You get two G3 pods in the box, each with a built-in mesh coil that delivers smooth and consistent flavour. The top-fill design makes refilling simple without removing the pod from the device, and Uwell’s leak-resistant technology helps stop any leakage issues. There’s a Smart Mode that automatically sets the right wattage for the pod, but you can also adjust the power manually if you want more control.

Colours

Compatible E-Liquid

The Wholesale Uwell Caliburn G4 works best with 50/50 or higher VG e-liquids. Most UK vapers get the smoothest flavour and good coil life when using 50VG/50PG or 60VG/40PG mixes. You can use both freebase e-liquid and nicotine salt e-liquid, depending on your preference and nicotine strength.

For mouth-to-lung (MTL) vaping, which this vape kit is mainly designed for, we recommend 50/50 nic salts or freebase liquids in strengths from 3mg up to 20mg. If you prefer a slightly more open restricted direct-to-lung (RDTL) draw, a 60VG mix will still perform well without leaking. Avoid very high VG liquids (70VG and above) as they can sometimes cause leaking or poor wicking in the G3 pods.

How to use

Using the Uwell Caliburn G4 Pod Vape Kit is straightforward. When your kit arrives, take out one of the G3 pods and fill it with your chosen e-liquid through the top-fill port by lifting the silicone plug. Put a couple of drops of e-liquid directly onto the coil if you want, then close the plug and slot the pod back into the device. Let it sit for 5 to 10 minutes so the coil can soak up the liquid properly. To turn the device on, click the button five times quickly. You can then vape by simply drawing on the mouthpiece – it’s inhale-activated – or press the button while you draw if you prefer. Use the slider on the side to adjust the airflow to your liking: tighter for a more cigarette-like mouth-to-lung draw, or slightly looser for a restricted direct-to-lung feel.

Once you start vaping, keep an eye on the OLED screen to check your battery level and wattage. The Smart Mode will automatically choose the right power for the pod, but you can change it manually if you want. When the e-liquid runs low, just top it up the same way without removing the pod. You’ll know it’s time to change the pod when the flavour starts to taste weaker or a bit burnt. At that point, simply pull out the old pod and click in a new one. Charge the battery with the USB-C cable whenever it gets low – a full charge normally takes less than an hour. Always store the device and spare pods in a cool, dry place away from direct sunlight to keep everything working properly.

Explore the Uwell Caliburn G4 Pod Vape Kit Range

The Wholesale Uwell Caliburn G4 Pod Vape Kit comes in a range of smart, modern colours that suit most vapers in the UK. You can choose from Flamingo Red, Glacier Blue, Gunmetal Grey, Polar Black, Sahara Gold, Seashell White, or Twilight Silver. Each colour looks clean and professional, so whether you want something bright or a more subtle finish, there’s an option that fits your style. The device itself feels solid in the hand and is small enough to carry around all day without being bulky. Because it supports both mouth-to-lung and a slightly more open draw, it works well for people who are switching from smoking as well as those who already vape regularly.

What makes the Caliburn G4 range practical is how easy it is to live with day to day. The 1300mAh battery gives you decent runtime, the top-fill pods make refilling quick and mess-free, and the mesh coils deliver steady flavour without much fuss. You can easily switch between different e-liquid flavours as the pods are simple to change. Many UK vapers keep one device for everyday use and appreciate that it needs very little maintenance compared to more complicated kits. Whether you’re at work, traveling, commuting, or just relaxing at home, the Caliburn G4 offers a reliable and no-nonsense vaping experience that most people settle into quickly.
