Troubleshoot Issues with Your Vape Cartridge
oil cartridge
troubleshooting
If your cartridge isn’t working properly, give these solutions a try. If the issue persists, return it to the store where it was purchased or contact us for assistance.
Cartridge Won’t Produce Vapor
Cold temperatures can thicken the extract. Warm the cartridge using a preheat function, hand warmth, or a hairdryer on low.
Use a fully charged battery producing less than 4 volts.
Take a few gentle, sip-like puffs and repeat warming if needed.
If clogged, gently heat the bottom where air enters and remember to keep the cartridge upright to prevent clogging.
If no vapor forms, slightly loosen the cartridge from the battery (¼ turn counterclockwise) and test again.
Vapor Hits Are Too Light
Use a fully charged battery with at least 280mAh and 4 watts of power.
Warm the cartridge until air bubbles move when tilted.
Take a few light puffs to prime the coil.
If these steps don’t work
Your coil may have burned out, often due to using a battery over 4.2 volts.
Always use batteries that operate at 4.2 volts or lower.
Cold Weather Tips
Extracts may become thick in cold temperatures, preventing vapor production. Make sure you store your cartridge indoors!
Warm your cartridge and prime it as outlined above. Once warmed, it should function normally.
