The Uwell Caliburn G / G2 Coils essentials in 10 seconds
- Mesh Technology: The 0.8 and 1.2 ohm variants use a UN2 mesh core that heats the e-liquid uniformly, preventing any hot spots and generating dense, flavorful clouds.
- Zero Hassle: Their design is threadless. They press-fit into the base of the cartridge by aligning the guide notch, ensuring a perfect and leak-free seal.
- Maximum Compatibility: Uwell unified its coil standard, meaning these exact same bobbins fit into a massive catalog of G and Tenet series devices.

Customize your vaping experience
Select the ohm rating that best suits your liquid:
- 0.8 ohm Mesh: Geared toward RDL (Restricted Direct Lung) vaping. Produces the warmest and thickest vapor in the family. Maximizes the sweetness of fruity liquids.
- 1.0 ohm Regular: Uses classic wire. Offers a firm and traditional MTL draw, with a very pronounced throat hit and highly efficient battery consumption.
- 1.2 ohm Mesh (G2 Coil): The ultimate choice for Nicotine Salts. The mesh delivers a hyper-clean flavor, while the high resistance softens the nicotine delivery so it doesn't irritate your throat.


Frequently Asked Questions about Caliburn G / G2 Coils
Why is my cartridge leaking immediately after changing the coil?
Look closely at the base of the coil: it has a flat edge on one side. The cartridge also has a flat mark on the insertion hole. You must ensure you push the coil in by aligning that flat mark; if you insert it twisted, it will not seal and the e-liquid will drain out completely.
I have the original Caliburn G, can I use the 1.2 ohm (labeled G2)?
Yes, absolutely. The entire coil series (0.8, 1.0, and 1.2) share the exact same outer mold. The 1.2 was launched alongside the Caliburn G2 (which is why they call it the G2 Coil), but it fits and works wonderfully in the original Caliburn G and Koko Prime.
