Why Choose the UWell Caliburn G4 Vape Kit?
1300mAh Battery for Longer Vaping
The built-in 1300mAh battery gives the device the power needed for regular vaping. Its integrated design keeps the kit compact and removes the need to carry a separate external battery.
Battery life depends on your wattage, pod resistance and vaping frequency. Lower-powered MTL vaping may use less power, while higher-powered vaping can consume the battery faster.
35W Output for Personalised Performance
The adjustable 5–35W output lets you control the intensity of your vape. Lower settings can create a cooler, more restrained draw, while higher settings can produce warmer vapour and a fuller output with a suitable pod.
Increase the wattage gradually and remain within the range recommended for your pod. This helps you find the right balance of flavour, vapour and warmth.
Storm Mode for Faster Vapour Delivery
Storm Mode delivers a faster, more energetic vaping experience. It suits moments when you want a stronger-feeling draw and quick vapour production. This mode adds a livelier response to your inhale, making each puff feel more immediate. Use it with a suitable pod and wattage setting for the best result.
Waves Mode for Smooth, Steady Puffs
Waves Mode creates a smoother and more consistent vaping rhythm. It suits relaxed sessions when you want a steady draw with controlled vapour production. Switch between Storm Mode and Waves Mode according to your mood. One gives your vape extra energy, while the other keeps the experience calm and even.
PRO-FOCS 4.0 for Richer Flavour
The Caliburn UWell vape experience is centred around flavour. PRO-FOCS 4.0 technology works with the Caliburn GPP pod platform to help deliver a fuller and more satisfying taste from your e-liquid. The right result will also depend on your chosen flavour, pod resistance, wattage and puff length. Start with the recommended settings, then adjust gradually to find the taste you enjoy most.
35% Longer Cartridge Lifespan
Uwell’s updated GPP cartridge system offers up to 35% longer cartridge lifespan under laboratory test conditions. This can help you enjoy a pod for longer before a replacement is needed.
Actual pod life varies according to e-liquid type, vaping frequency, wattage and puff duration. Replace the cartridge when the flavour fades, vapour production drops or a persistent burnt taste develops.
0.85-Inch Colour Display for Easy Control
The 0.85-inch HD colour screen puts useful information in view. Check your battery level, wattage, puff count, selected mode and other device settings without guessing.
The display also adds a more engaging feel to the kit. Select from the available interface options and keep an eye on your vaping information throughout the day.
1300mAh Power with USB-C Charging
The USB-C charging port gives you a modern way to recharge the device. It connects easily with a suitable cable and supports 5V/2A fast charging.
Charging performance depends on the power source and cable used. Avoid using damaged cables and recharge the kit on a stable surface away from heat and moisture.
Adjustable Airflow for MTL and RDTL
The airflow system gives you several ways to change the draw. Slide the airflow valve, change the pod orientation or use both adjustments together.
A tighter setting can suit MTL vaping, which creates a controlled, cigarette-style inhale. A more open setting can support RDTL vaping with a looser draw and fuller vapour output. Try small adjustments until the draw feels right. Your preferred airflow may change when you switch pod resistance or e-liquid.
Leak-Resistant GPP Pod Construction
The Caliburn GPP cartridges use Uwell’s U² technique, which combines ultrasonic welding with a U-shaped airflow channel. This supports the pod’s leak-resistant performance and helps guide airflow through the cartridge.
The clear juice window also lets you check your e-liquid level before it runs low. Refill the pod before the e-liquid is fully depleted to help protect the coil.
Uwell Caliburn G4 Pod Compatibility
The G4 works with compatible Caliburn GPP cartridges. These pods are available in several resistances, giving you options for tighter MTL vaping or a more open RDTL draw.
Common GPP options include:
-
0.4Ω for higher-powered vaping.
-
0.6Ω for a balanced RDL or open MTL experience.
-
0.9Ω for a more restricted MTL draw.
-
1.2Ω for lower-powered MTL vaping.
Always follow the recommended wattage printed on the pod or packaging. Using the correct setting helps protect the coil and supports consistent flavour.
Browse our Uwell Caliburn Pods collection when you need replacement cartridges. Our collection includes GPP, G3, G2, A2 and A3/A3S pod types.
The older Uwell Caliburn G replacement pods belong to the wider Caliburn G pod range. Check the compatibility information carefully before ordering, as these older pods should not be assumed to fit the G4.
Refillable Pods for Your Favourite E-Liquid
The GPP cartridges let you use your own e-liquid and explore different flavour profiles. A 50% VG e-liquid is a suitable starting point for the pod types used with this kit.
Nicotine salts can work well with lower-powered MTL pods, while suitable 50/50 freebase e-liquids give you another option. Match the nicotine strength and VG/PG ratio to your chosen pod and vaping style.
The pod uses an integrated coil, so there is no separate coil to remove. When the coil reaches the end of its useful life, replace the cartridge and refill the new one.
How to Fill and Use the Uwell Vapes
-
Charge the kit. Connect a compatible USB-C cable to the charging port.
-
Remove the cartridge. Lift the pod from the top of the device.
-
Open the fill area. Remove the pod cap to access the fill port.
-
Add e-liquid. Fill through the correct opening without overfilling.
-
Prime the cartridge. Let a newly filled pod stand for several minutes.
-
Insert the pod. Place it into the device until the magnetic connection holds it securely.
-
Turn on the device. Press the power button five times.
-
Select your mode. Choose Storm Mode or Waves Mode.

Set the wattage. Use a suitable output for your pod resistance.
-

Take gentle puffs when using a new cartridge. This allows the e-liquid to reach the mesh coil and helps you settle into the flavour.

Know When to Replace Your Pod
A fresh cartridge can restore flavour and vapour when your current pod starts to decline. Replace it when you notice:
-
A persistent burnt taste.
-
Weak or muted flavour.
-
Lower vapour production.
-
Gurgling or inconsistent performance.
-
Visible damage to the cartridge.
-
An e-liquid level that has reached the bottom.
Do not continue using a pod that tastes burnt. Remove it, fit a compatible replacement and allow the new cartridge to soak before vaping.
For the wider Uwell Caliburn G Pods system, check the product information carefully to confirm that the cartridge suits your device.
