Built Small. Performs Big.
PRO-FOCS 4.0 Flavour Technology
The same cutting-edge flavour system found in the full Caliburn G4, delivering a 35% improvement in flavour satisfaction and 35% longer coil lifespan over previous Caliburn generations.
35W Output in a Compact Body
Despite its smaller dimensions, the G4 Mini pushes up to 35W through CALIBURN GPP coils, providing a genuinely powerful vaping experience that punches well above its size.
1100mAh Battery with Type-C Charging
A capable 1100mAh battery delivers solid all-day performance, with fast USB-C charging to top you back up quickly whenever you need it.
Auto-Draw Activation
Simply inhale to fire. Auto-draw detection removes the need for a button, making the G4 Mini one of the most natural and intuitive pod kits in the Caliburn lineup.
Dual Adjustable Airflow
The combination of a side-mounted slide valve and pod rotation lets you dial in your preferred draw resistance precisely, from a tight MTL to a more open restricted draw.
U2 Anti-Leak Technology
Ultrasonic welding and Uwell's U-shaped internal channel design combine to provide exceptional leak resistance, keeping the device clean and performing reliably every day.
Four Reasons to Pick the Caliburn G4 Mini
A Brand Built on Flavour and Innovation
Founded in 2015, Uwell has grown from a specialist coil manufacturer into one of the most respected names in the vaping industry. The brand made its reputation with the original Caliburn, which became the world's best-selling pod kit, and has since continued to push the boundaries of flavour and performance through continuous R&D investment. Uwell's engineering-first approach is evident across every product: from the precision of the CALIBURN GPP coil platform to the leak-resistant U2 ultrasonic welding process. Today, Uwell products are sold in over 100 countries and trusted by millions of vapers who prioritise taste above everything else.

How to Use the Uwell Caliburn G4 Mini
Step 1: Fill the Pod
Remove the pod from the device and locate the side-fill port. Fill with up to 2ml of your preferred e-liquid, then firmly close the fill port seal to prevent leaking before reinserting.
Step 2: Prime the Coil
After filling, leave the pod to sit for 5 to 10 minutes before taking your first draw. This allows the e-liquid to fully saturate the mesh coil, preventing dry hits and maximising coil life.
Step 3: Insert the Pod
Slide the filled pod back into the device until it clicks securely. Rotate the pod to your preferred airflow position before you start vaping.
Step 4: Charge If Needed
Connect the USB-C cable to charge the 1100mAh battery. The clear-view window lets you monitor your e-liquid level while the device charges, so you are always ready to go.
Step 5: Adjust Airflow
Use the side slide valve to fine-tune your airflow resistance. Combined with pod rotation, this allows you to find the perfect draw from tight MTL to a more open restricted style.
Step 6: Inhale to Vape
The G4 Mini is auto-draw activated. There are no buttons to press. Simply inhale from the mouthpiece and the device fires instantly, delivering smooth and flavour-rich vapour with every puff.

Frequently Asked Questions
What is the difference between the Caliburn G4 and the G4 Mini?
The G4 Mini is a smaller, more minimalist version of the Caliburn G4. The key differences are a slightly smaller 1100mAh battery (vs 1300mAh), no built-in display screen, and a cleaner auto-draw-only design. Both share the same PRO-FOCS 4.0 technology, 35W output, and full CALIBURN GPP cartridge compatibility.
Does the G4 Mini have a display screen?
No. The Caliburn G4 Mini does not include an LED or colour display. Instead it features a clear-view juice window so you can monitor your e-liquid level at a glance. If a display screen is important to you, the standard Caliburn G4 includes a 0.85 inch HD colour screen.
How does the G4 Mini fire? Is there a button?
The G4 Mini uses auto-draw activation. There is no firing button. Simply inhale from the mouthpiece and the device detects your draw and fires automatically, delivering a smooth and instant vaping experience.
What pods and coils are compatible with the G4 Mini?
The Caliburn G4 Mini is compatible with all CALIBURN GPP cartridges, including the upgraded range. Available coil resistances include 0.4ohm (RDTL), 0.6ohm, 0.9ohm (MTL), and 1.2ohm. G3 series pods are also compatible.
What e-liquids work best in the G4 Mini?
For the 0.9ohm and 1.2ohm MTL pods, nicotine salt e-liquids between 10mg and 20mg are recommended for the smoothest experience. For the 0.4ohm and 0.6ohm pods, lower nicotine freebase or 50/50 e-liquids between 3mg and 6mg are ideal.
