UWELL COILS

Resistances are the options stocked for each family. Availability varies - check the product page.

Match the generation, not just the name. Crown 3, Crown 4 and Crown 5 coils are different fittings. The number printed on your tank is what matters.

You want maximum vapour - the Valyrian 2 coils go down to 0.14 ohm, the lowest resistance stocked here, and are built for high-wattage direct-lung vaping.

You want a balance of flavour and coil life - the 0.3 and 0.4 ohm options in the Crown 4 and Crown 5 families draw less power and last noticeably longer than sub-0.2 ohm builds.

You are after a Caliburn part - Caliburn devices take pods, not tank coils. Those are in the Uwell pods collection.

The Crown series is one of the longest-running sub-ohm tank lines in vaping, and Uwell has kept coils available across several generations - which is also why matching the generation matters so much.

Resistance sets behaviour. Lower resistance draws more power, makes more vapour and heat, and consumes e-liquid faster. Higher resistance runs cooler and tighter and generally lasts longer. Stay inside the wattage range printed on the coil.

Prime every new coil: e-liquid onto the exposed cotton, fill the tank, then wait several minutes before firing. A dry first fire is the usual cause of a burnt taste on a brand-new coil.
