Fatures of the eGo-C Twist:

Unique twist-dial increments your voltage from 3.2v to 4.8 in .2v increments. Dial is clearly marked.

BUCK-Boost circuitry provides constant voltage at your desired setting until battery shuts off (we always recommend starting at the lowest setting when changing/mounting atomizers and cartomizers and then working up to your vaping delight - remember, TWIST down before screwing on)

eGo-C battery advanced protection features - short circuit cut-off, 10 second button press cut-off, 5 click ON/OFF (the battery will probably be shipped to you in the OFF position).
