The Uwell Crown 4 IV Replacement Coils offers a highly advanced atomizer technology, featuring double helix mesh designs with self-cleaning technology. The coils are available in two resistances - The 0.23ohm FeCrAl UN2 Coil and the 0.4ohm Dual SS904L Coil. Both of these coils are rated at 60-70 watts and it's down to personal preference on which you prefer.
How to change the Crown 4 coil
Ensure the tank is empty before changing the coil. Unscrew the bottom cap of the tank and pull out the old coil. Push the new coil into place and replace the bottom cap. Allow the e-liquid to soak into the coil for 15 minutes before initially vaping.
