What are dab pen coils?
A dab pen coil is the heating element. It turns cannabis concentrate into vapor. Coil types differ in material and shape. Maintenance means cleaning, burn-off, and replacement.
Coil material affects flavor, vapor, and heat time. Each material has a recommended wattage or voltage. Match the coil to your battery.
Coil types
- Quartz coils heat fast. They give flavor.
- Ceramic coils hold heat. They work at low temperatures.
- Titanium coils resist corrosion. Heat range is 300 to 500 degrees Fahrenheit.
- Kanthal coils have resistance of 1.0 to 3.0 ohms. Use 5 to 15 watts.
- Nichrome coils heat at low voltage. Use 3.2 to 4.8 volts.
- Stainless steel coils work with temperature control. Resistance is 0.5 to 1.0 ohm.
Dual and quad coils add surface area. They make more vapor. They also use more power.

Maintenance steps
- Remove the coil from the pen.
- Soak the coil in 91% isopropyl alcohol for 15 minutes.
- Use a cotton swab to remove residue.
- Let the coil dry for 10 minutes.
- Do a burn-off at 5 to 15 watts. Do not exceed 20 watts.
- Replace the coil after 1 to 2 weeks of daily use.
Do not use water. Water can damage the coil. Do not soak the battery. Keep the pen upright. Store it away from heat.
Clean the coil after every 3 to 5 grams of concentrate. A dirty coil wastes oil. A clean coil gives full flavor.
Signs of a worn coil
- Weak vapor.
- Burnt taste.
- Clogged airflow.
- Dark residue.
- Uneven heating.
Replace the coil when these signs appear. A new coil costs $5 to $15. A new pen costs $20 to $80.
Safety notes
Use legal cannabis. Check your local laws. Do not use a damaged battery. Do not disassemble a coil. Follow the device manual. Consult a doctor for health questions.
