Uwell Caliburn G4 Vape Kit

The Uwell Caliburn G4 is a versatile flavor-oriented pod vape that has functionalities. It includes a 1300mAh internal battery and can fast charge with USB-C. The device also displays the puffs that you have on its 0.85 inch color display, the wattage, battery charge and mode information. Its pods have in-built mesh coils and Pro-FOCS / U2 technologies of anti-leakage accepted by Uwell. Activation It can be of two types; draw-activated inhalation and side fire button is on. A sliding side valve can control airflow, and may also be achieved by rotating the orientation of the pod to provide a range of tight MTL (mouth-to-lung) to more relaxed restricted DTL draws.

E-liquid and nicotine

The Caliburn G4 Vape Kit comes with a refillable pod with a standard 2 ml capacity of e-liquid that was intended to accept both Nicotine salt and freebase e-liquid. It may be programmed to contain a very wide range of nicotine doses, commonly, between 3 mg and 20mg, depending on which type of e-liquid and coil is fitted. To obtain a more enjoyable, easier hit, especially by using the mouth-to-lung (MTL) mode and increased resistance coils, a user will prefer to use nicotine salts within the spectrum of 10 - 20 mg. Freebase nicotine in a lower dosage of 3-6mg is more common when it is vaped in lower-resistance coils of lower-resistance direct-to-lung (RDL) vaping. This versatility makes Caliburn G4 appropriate to the needs of both the smokers in the transition and the experienced vapers who require the capacity to change the nicotine delivery to align it with their needs.

Design features

The Uwell Caliburn G4 has a smooth and compact shape which is constructed with a lightweight aluminum alloy frame and smooth curves that are easy to hold and carry. It is clean and minimalistic in its aesthetic, with a matte finish or slight color gradients, and complemented by a small color display screen which makes viewing of settings and status easy. The pod attaching part is magnetic and just snaps in, and the transparent sides of the pod enable the user to view the remaining e-liquid. The device has also got user friendly control buttons and side trim accent which give the device style and feel. All in all, it is a sleek, ergonomic design that creates a balance between the aesthetics and practicality.

TPD compliance

The Uwell Caliburn G4 has been legally manufactured within the TPD (Tobacco Products Directive) regulations in the EU, and hence the e-liquid volume and childproofing regulations. That way, its pods in TPD markets usually have a capacity of 2mL of e-liquid. In addition, the refill port must be child-resistant (e.g. silicone plug or safety seal). Lastly, labeling and packaging should comply with the regulation e.g. warning statements, nicotine strength limitation and lot/batch markings. Practically, it is to say that the Caliburn G4 sold in the EU/UK will not have the same pod design and capacity as the version sold in other countries, to remain legal under TPD restrictions.

How to use Uwell Caliburn G4

Unbox the Device: Remove the Caliburn G4, pod, and accessories from the packaging.
Charge the Battery (if needed): Use a USB-C cable to fully charge the device before first use. The screen will display the charging status.
Install the Pod: Insert the refillable pod (with pre-installed coil) into the device until it clicks into place magnetically.
Fill the Pod with E-Liquid: Remove the mouthpiece by gently snapping it off. Locate the red fill port and insert your e-liquid nozzle. Fill the pod (up to 2 mL in TPD-compliant models). Close the port securely and reattach the mouthpiece.
Let the Coil Prime: Wait 5-10 minutes after filling to allow the coil to soak in the e-liquid and prevent dry hits.
Turn On the Device: Press the fire button 5 times quickly to turn the device on/off.
Adjust Settings (Optional): Use the screen and button to adjust wattage or view battery and puff data.
Vape: Inhale directly (auto-draw) or press the fire button while inhaling. Adjust airflow by rotating the pod or using the side airflow slider if desired.
Refill or Replace the Pod: Refill when e-liquid is low. Replace the pod if flavor drops or coil feels burnt.
