KangerTech has ceased production of Protank Coils and Dual Coils. Instead, they have come out with a new series of coils that are compatible with Protank 1 & 2 models and a series compatible with Protank 3 and Aerotank models.
SOCC - Protank 1 / Protank 2 - $2.50
Single Organic Cotton Coil
Available in resistances of 1.5ohm, 1.8ohm, 2.2ohm, 2.5ohm
VOCC - Protank 3 / Aerotank - $3.50
Vertical Organic Cotton Coil
Available in resistances of 0.8ohm, 1.0ohm, 1.2ohm, 1.5ohm, 1.8ohm
These new coils use Organic Cotton wicks instead of of synthetic fiber material in their previous coils. This means these coils MUST be fully saturated with liquid before firing. Even a short dry burn will ruin the coil. After filling with eLiquid, it is recommended that the user wait 30+ seconds before firing.
The advantage of Organic Cotton is better vapor production, and a cleaner, more authentic taste.
