Uwell Caliburn G4 Pro Pod Kit
The Uwell Caliburn G4 Pro Pod Kit is a landmark device: the first Caliburn to feature a full touchscreen interface. A 2.51 inch touch display puts four output modes, six UI themes, eight language options, and a full settings hub at your fingertips. A substantial 1800mAh battery delivers serious all-day runtime, and PRO-FOCS 4.0 flavour technology ensures every draw is rich and satisfying through the 2ml refillable GPP pod. Whether you want the raw intensity of Storm Mode, the smooth delivery of Waves Mode, or the precision of Custom Mode with its adjustable three-stage power curve, the G4 Pro puts you in complete control.
The Most Advanced Caliburn Ever Made
2.51 Inch Touchscreen Interface
Uwell's first smart touchscreen brings full swipe and tap control to a pod kit. Access modes, brightness, UI themes, language settings, and device renaming all from the vivid display — no complex button sequences required.
Four Output Modes Including Custom Mode
Choose from Smart Mode (automatic power matching), Storm Mode (intense throat hit), Waves Mode (smooth pulsed delivery), or Custom Mode, which lets you set distinct power levels for the start, middle, and end of each puff.
1800mAh Battery with Fast USB-C Charging
One of the largest batteries available in a compact pod kit. The 1800mAh cell provides extended all-day vaping performance, backed by 5V/2.5A USB-C fast charging to get you back to full capacity quickly.
PRO-FOCS 4.0 Flavour Technology
The G4 Pro pairs the advanced PRO-FOCS 4.0 coil system with its intelligent output modes, delivering 35% more flavour satisfaction than previous Caliburn generations and a 35% increase in coil lifespan.
Stepless Airflow Control
A precision stepless slider gives you infinitely adjustable airflow resistance, allowing you to fine-tune your draw from a tight MTL pull right through to a more open, unrestricted inhale without fixed notches.
U2 Anti-Leak and Droplet E-Liquid Window
The G4 Pro features Uwell's U2 anti-leak technology through ultrasonic welding and a U-shaped internal channel, paired with a droplet-shaped e-liquid window for easy level monitoring at a glance.
Four Reasons the G4 Pro Is Worth It
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. The G4 Pro represents the brand's most ambitious pod kit to date, combining touchscreen technology with four intelligent output modes in a platform already trusted by millions worldwide. Uwell products are sold in over 100 countries and backed by the same rigorous quality control that has defined the Caliburn name for nearly a decade.

How to Use the Uwell Caliburn G4 Pro
Step 1: Fill the Pod
Remove the pod and locate the side-fill port. Fill with up to 2ml of e-liquid, then reseal the fill port firmly. Allow 5 to 10 minutes for the coil mesh to saturate before your first draw.
Step 2: Insert the Pod and Power On
Slide the filled pod into the device until it clicks securely into place. Power on the G4 Pro by tapping the screen. The touchscreen will illuminate and display your current settings.
Step 3: Select Your Output Mode
Swipe down to access the Smart Settings hub. Choose from Smart Mode, Storm Mode, Waves Mode, or Custom Mode. For your first use, Smart Mode is recommended as it automatically sets the ideal output for your coil.
Step 4: Configure Custom Mode (Optional)
To use Custom Mode, set your preferred wattage for the start, middle, and end stages of each puff independently. This three-stage curve allows precise control over warmup, peak output, and cool-down for a tailored vaping experience.
Step 5: Adjust the Airflow
Use the stepless airflow slider on the device body to set your preferred draw resistance. Slide toward closed for a tighter MTL draw, or open for a more airy, unrestricted inhale.
Step 6: Personalise Your Display
Swipe through the settings to choose one of six UI themes, adjust screen brightness and timeout, and select your preferred display language from eight available options. You can also rename the device to your preference.
Step 7: Charge via USB-C
When the battery is low, connect the USB-C cable for fast 5V/2.5A charging. The 1800mAh battery and fast charging combination means downtime is kept to an absolute minimum.

Frequently Asked Questions
What is the difference between the Caliburn G4 Pro and the standard G4?
The G4 Pro has a significantly larger 1800mAh battery (vs 1300mAh), a full 2.51 inch touchscreen interface (vs a 0.85 inch display), four output modes including the advanced Custom Mode, and stepless airflow control. It is the more feature-rich and premium option in the G4 family.
What is Custom Mode on the Caliburn G4 Pro?
Custom Mode allows you to independently set the wattage for three phases of each puff: the initial hit (start), the main draw (middle), and the tail-end of the inhale (end). This creates a personalised power curve that can improve flavour, manage warmup, and extend coil life based on your exact vaping style.
Is the G4 Pro compatible with existing CALIBURN GPP cartridges?
Yes. The Caliburn G4 Pro is fully compatible with all CALIBURN GPP cartridges. The kit includes two pods: a 0.4ohm and a 0.6ohm. Additional 1.2ohm pods are also compatible for tighter MTL vaping.
What e-liquids should I use with the G4 Pro?
Nicotine salt e-liquids and 50/50 freebase liquids work best. High-VG e-liquids above approximately 70% VG are not recommended as they may not wick efficiently through the GPP coils and could result in dry hits or reduced flavour performance.
How long does the 1800mAh battery last?
Battery life will vary depending on your chosen output mode and how frequently you vape. Most users can expect a full day of regular use from a single charge. Charging from low to full takes approximately 40 to 60 minutes via USB-C at 5V/2.5A.
Is the Caliburn G4 Pro TPD compliant?
Yes. The pod capacity is 2ml, which fully complies with UK Tobacco and Related Products Regulations (TPD). All Uwell products sold at Hulme Vapes meet current UK regulatory requirements.
