How to Use the Uwell Caliburn G4 Pro Vape Kit

Getting started with the Uwell Caliburn G4 Pro is quick and straightforward. Follow these simple steps to set up your device and enjoy a smooth, flavourful vaping experience:

Unbox the Device

Remove the Caliburn G4 Pro and all accessories from the packaging. Ensure all components, including the pod and charging cable, are included.

Prepare the Pod

Take one of the included GPP pods (0.4Ω or 0.6Ω). Remove the protective seals from the contacts and mouthpiece before use.

Fill the Pod with E-Liquid

Open the side-fill port and carefully fill the pod with your preferred e-liquid, ideally a 50/50 freebase or nicotine salt formula. Avoid overfilling to prevent leakage.

Prime the Coil

Allow the filled pod to sit for 2–3 minutes before use. This helps the coil absorb the e-liquid properly, preventing dry hits.

Insert the Pod

Push the pod firmly into the device until it clicks into place. The magnetic connection ensures a secure and stable fit.

Power On & Unlock the Screen

Tap the display to wake the device. Use the touchscreen controls to adjust wattage, switch modes (Smart, Storm, Wave, or Custom), or view puff information.

Adjust Airflow (Optional)

Use the stepless airflow slider on the side of the device to customise your draw, tighter for MTL (mouth-to-lung) or looser for RDL (restricted direct-lung) vaping.

Inhale to Vape

Simply inhale through the mouthpiece to activate. The device delivers a responsive and consistent vape every time.

Recharge When Needed

When the battery indicator shows low power, connect the USB-C cable to recharge. Thanks to 5V/2.5A fast charging, a full charge takes under 45 minutes.

Frequently Asked Questions

What e-liquid is best for the Uwell Caliburn G4 Pro Vape Kit?

The Uwell Caliburn G4 Pro works best with nicotine salt e-liquids that have a 50/50 VG/PG ratio. This provides smooth flavour and consistent vapour. You can also use 50/50 freebase e-liquids if you prefer a stronger throat hit, but high VG (70/30) blends are not recommended as they can affect flavour and coil life.

How long does the Caliburn G4 Pro battery last?

The Caliburn G4 Pro features a 1000mAh rechargeable battery that easily lasts a full day for moderate users. It supports 2.5A USB-C fast charging and can fully recharge in about 40 to 45 minutes. Battery duration may vary depending on your wattage setting and how frequently you vape.

Are Caliburn G and G2 pods compatible with the G4 Pro?

No, the Caliburn G4 Pro only supports GPP pods, designed specifically for this model. These pods deliver better coil performance, improved leak resistance, and enhanced flavour compared to older Caliburn pods.

When should I replace the Caliburn G4 Pro pod?

Replace the pod when you start noticing a burnt or dull flavour, reduced vapour, or darker e-liquid. On average, a pod lasts for about 10 to 15 refills depending on your usage. Replacing it regularly ensures better flavour and a smooth vaping experience.

Does the Caliburn G4 Pro use a button or auto draw system?

The Caliburn G4 Pro is designed with a button-free auto-draw system. You simply inhale through the mouthpiece to activate the vapour, making it simple and ideal for beginners or users who prefer convenience.

What is the wattage range of the Caliburn G4 Pro?

This device supports a 5W to 35W adjustable wattage range. You can manually change the wattage using the touchscreen or activate Smart Mode, which automatically sets the best power level based on your installed coil.

How does the airflow adjustment work?

The Caliburn G4 Pro features a precision airflow slider on the side. You can adjust it for a tighter mouth-to-lung (MTL) draw or a looser restricted direct-lung (RDL) experience, giving you full control over your preferred inhale style.

Does the Caliburn G4 Pro prevent leaking?

Yes, the GPP pods are equipped with Uwell’s Pro-FOCS flavour technology and a triple-seal anti-leak design. This advanced system minimizes condensation and prevents e-liquid from leaking, keeping your vape clean and mess-free.

What information does the G4 Pro screen display?

The smart OLED touchscreen shows all key vaping details, including wattage, battery percentage, coil resistance, puff counter, and current mode. It’s easy to read, responsive, and makes adjusting settings quick and simple.

How can I clean and maintain my Caliburn G4 Pro Kit?

To maintain performance, clean the pod and device contacts with a dry cloth weekly. Avoid water exposure, always store the device upright, and use only genuine Uwell pods and coils. Proper maintenance ensures the best flavour and extends device lifespan.
