Different cartridges will use different coils to produce vapor. The Special-K cartridge uses a Cotton and steel coil, which will affect the taste of your vapor. It is not harmful, but may be different than other cartridges you've tried previously!

This may indicate damage to the battery, or a faulty charger. Overtightening of the cartridge may cause damage to the battery, as will improper cleaning, or even supercharging of the battery. Make sure to only use the charging equipment that comes with your device. If this problem persists, please contact support@kandypens.com
