Detailed informations: 
The EGO-C Twist battery is another advanced vision based on EGO-C original battery. We modified the circuit to enable the adjustment of output voltage from 3.2V to 4.8V. With a smart Buck-Boost converter inside, you can spin the knob at the bottom to adjust the output voltage depend on your need. 

Accurate adjustment of output voltage 
There are altogether 8 grids on the knob at the bottom, and each represents 0.2V. Spin the knob in a clockwise direction to increase output voltage and spin the knob in an anticlockwise direction to decrease output voltage. Higher output voltage gives more vapour. You can adjust the output voltage so easily and enjoy the whole vapour time. 

This battery also has the previous lock/unlock function. 
The protection switch makes it safer and easier to use and this can prevent accodental battery discharge when not in use. 

Screw battery into the hole on the atomizer and gently push the tank cartridge into the atomizer, then it's ready use. 

Battery can be easily charged with the assorted USB chargers and there are various chargers for your choices.
