The eGo-C Twist Variable Voltage battery is another advanced version based on eGo-C original battery. Joyetech modified the circuit to enable the adjustment of output voltage from 3.2V to 4.8V as the lithium battery power decrease. With a smart Buck-Boost converter inside, you can spin the knob at the bottom to adjust the output voltage depend on your need.
A fully charged 1000 mAh eGo C Twist variable voltage battery can support you 6 hours, it takes 2-3 hours to be fully charged using fast USB charger for eGo/eGo-T/eGo-C! Using the battery at a higher voltage output will drain the battery quicker than when using it at a lower voltage.
How to adjust the output voltage?
There are 8 grids on the knob at the bottom, and each represents 0.2. Spin the knob in a clockwise direction to increase output voltage and spin the knob in anti-clockwise direction to decrease output voltage. High output voltage gives more vapor. You can adjust the output voltage so easily and enjoy the whole vapor time.
