The Joye eGo-C 1000mA "Twist" is Joyetech's first variable voltage battery that allows the user to adjust the voltage output to give a customed vaping experience. To adjust simply twist the dial at the end of the battery anywhere from 3.2V to 4.8V. Using a higher than normal voltage (3.7v) will drain the battery faster than using a lower voltage. The eGo-C Twist battery also comes with the "5-Click Protection" to keep the battery from accidentally being activated. To turn the battery on or off simply press the manual button 5 times within 2 seconds. The button will then flash once telling you that the battery is now on or off!
It is recomended to use the Joye eGo USB Battery Charger to charge the Joye eGo-C "Twist" battery.
