Uwell Caliburn G4 Classic Pod Vape Kit

Uwell Caliburn G4 Classic Pod Vape Kit

The Caliburn name has carried Uwell's pod range for a decade, and the G4 Classic is the anniversary edition of it. It pairs a 1400mAh battery with up to 35W, a stepless airflow slider and dual activation, so you fire it by button or simply by inhaling.

Two 2ml top-fill pods come in the box: a 0.4ohm for a warmer RDL draw, and a 0.9ohm for tight MTL, and the smart chip reads whichever one you fit and sets the power to match. USB-C charging, aluminium body, pocket-sized. It is one of the more polished Refillable Pod Kits around, and it sits happily beside the wider MTL Vape Kits range.

Why vapers choose this:

• Smart Mode does the thinking. Fit a pod, and the chip reads its resistance, then sets the wattage to match. No menus, no button combinations, nothing to get wrong on the first go.

• Two draws from one device. The 0.4ohm runs warmer and looser for RDL, the 0.9ohm pulls tight for MTL.

• Fire it your way, by pressing the button as you draw or just inhaling for auto-draw.

• 1400mAh stretches a long way in a pod this small.

• Top-fill pods with a leak-resistant seal, so refilling is a quick, clean job rather than a gamble with your pocket.

Uwell Caliburn G4 Classic Features

Smart Mode Sets the Power For You

This is the part that makes it beginner-proof. Drop in either pod and the device detects the coil resistance, then locks the output to the right range automatically. You do not choose a wattage or scroll a menu. Fit, fill, vape. For anyone who just wants a device that works without fuss, that alone is worth a lot.

Why Two Pods in the Box?

Because Uwell wants you to try both draw styles before settling. The pre-installed 0.4ohm leans warm and RDL, while the spare 0.9ohm gives a tighter MTL pull. Swapping between them takes seconds thanks to the magnetic pod fit, so you can find your preferred style on day one.

Flavour Is the Whole Point

Uwell's PRO-FOCS flavour tech is built into the pods to keep taste clean and consistent as the coil ages, rather than fading off after a few days. It handles nic salts and 50/50 blends well, so pair it with a bottle from the Nic Salts Range, and you get accurate flavour from the first fill to the last.

Stepless Airflow, Not Click-Stops

The airflow is a smooth recessed slider rather than fixed notches, so you can dial the draw exactly where you want it. Nudge it nearly shut for a cigarette-tight MTL inhale, or ease it wider for a softer, airier RDL feel. Small movements make a real difference, which is the point.

Fire It However You Like

Some days you want a button, some days you just want to inhale and go. The dual activation system gives you both, with twin sensors keeping the auto-draw responsive so it triggers cleanly every time. Honestly, most people settle on auto-draw and forget the button is even there.

How to Set Up the Uwell Caliburn G4 Classic

First run takes a couple of minutes. Do not rush the soak.

1. Charge the device fully over USB-C before first use. The RGB LED matrix shows the charge status as it fills.

2. Pull the pod free, flip open the top-fill port, and add your 50/50 or nic salt e-liquid to just below the max line, then close it firmly.

3. Push the pod back into the device. It seats with a magnetic click.

4. Leave the filled pod to stand for a slow five minutes so the coil wicks all the way through. New coils need that soak, and firing one dry scorches the cotton permanently.

5. Pick your firing style: hold the button as you draw, or simply inhale for auto-draw.

6. Set the airflow. Slide it toward closed for a tight MTL pull on the 0.9ohm, or toward wider for a looser RDL draw on the 0.4ohm.

What's in the Uwell Caliburn G4 Classic Box

Inside you get:

• the G4 Classic device,

• a pre-installed 0.4ohm pod,

• a spare 0.9ohm pod,

• and a user manual.

There is no e-liquid included, and note that the USB-C cable is not in the box, so pick one up from the Chargers And Cables range if you do not already have one. Pirate Vapes stocks spare GPP pods separately for when your coils wear down, and you will need your own bottle of juice to get started.

Works With the Caliburn GPP Pod Range

The G4 Classic runs on Uwell's Caliburn GPP pods, the shared cartridge platform used across the recent Caliburn generations. That means pod supply is simple and cross-compatible with the G3, G4 and G5 families rather than tied to this one device. Beyond the 0.4ohm and 0.9ohm pods in the box, the GPP range also covers 0.6ohm and 1.2ohm options if you want to fine-tune the draw.

Browse the full Uwell Vapes range for pods and matching gear. What it will not take: older Caliburn G, G2 and A2 pods, or cartridges from other brands. Match GPP to GPP, and you are sorted.

About Uwell

Uwell built its name almost entirely on the Caliburn line. Since the original landed, the series has become the go-to recommendation for anyone wanting a simple, reliable MTL pod, and the G4 Classic marks ten years of that run.

The shift to the shared GPP pod platform is the clever part: one cartridge type now spans several devices, so replacements stay easy to find and cheap to keep stocked. You can top up on GPP pods in the Uwell Coils section whenever a pod runs its course.

Stock Up and Save

Here is the maths that matters: once you own the kit, you are only buying pods and juice. A refillable setup costs a fraction of grabbing a fresh device every week, and with single-use disposables banned since June 2025, it is the sensible way to vape now.

Pirate Vapes keeps GPP pods and nic salts in stock so refills are never a scramble. Same-day dispatch before 4 pm, Free Pirate Post over £40, TPD compliant, age-verified checkout, over-18s only.

Conclusion

The Caliburn G4 Classic is Uwell doing what it does best: a compact, dependable pod kit that gets out of your way. Smart Mode handles the power, dual firing lets you vape how you like, and the shared GPP pods keep running costs low.

For a daily device that pairs with hardware and juice you can restock easily, it earns its place. Pick up spare pods and Vape Accessories, and grab yours from Pirate Vapes.

FAQs

What pods does the G4 Classic use?

Uwell Caliburn GPP pods. They are shared across the wider G3, G4 and G5 range, so they are easy to find and restock.

Is the G4 Classic MTL or RDL?

Both. The 0.9ohm pod with the airflow near closed gives a tight MTL draw, while the 0.4ohm pod with a wider setting opens into RDL.

Does the G4 Classic come with a charging cable?

No. The USB-C cable is not included, so use one you already have or add one to your order.

How long does the G4 Classic battery last?

The 1400mAh cell gets most people through a full day, sometimes longer on the higher-resistance pod. USB-C tops it back up quickly.

What e-liquid should I use with the G4 Classic?

Nic salts or 50/50 blends suit both pods best. The 0.9ohm takes 10mg to 20mg nic salt well for MTL; the 0.4ohm is happier at lower strengths.

Can I use my older Caliburn pods with the G4 Classic?

No. Older Caliburn G, G2 and A2 pods do not fit. Stick to GPP pods.
