We advise the following if your cartridge isn't heating up or creating any vapor:
- Check the cartridge to make sure it isn't damaged or compromised in any way that might prevent the heating element and cartridge from making appropriate contact.
- Confirm that your device is fully charged.
- Use a cotton swab soaked in isopropyl alcohol to clean the connecting point of any oil residue, dust, or other debris.
Please contact our customer service department at info@dubcharge.com if you're still having problems, and we'll be happy to assist you.
