IF YOU DO NOT ALREADY HAVE ONE, YOU NEED TO PURCHASE BOTH OUR JOYETECH HOME CHARGER AND JOYETECH FAST USB CHARGER CABLE TO CHARGE THESE BATTERIES SO THAT YOU WILL NOT HAVE ANY CHARGING ISSUES (SEE BELOW FOR CHARGERS). WE WILL NOT BE ABLE TO SUPPORT YOU IF YOU USE ANY OTHER CHARGER.

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.

It takes 3-4 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. Be careful not to damage atomizers/cartomizers. Driving them with too much power for too long or running them dry can burn them out. We recommend you starting with a low voltage setting and working your way up until you find the right setting for your atomizer/cartomizer.

It also comes with "5-click protection". Generally, the battery is shipped in the off position. In off position, it will not function even when pressing the button. To turn on battery, press manual button 5 times within 2 seconds. You will see white LED flash. To turn off battery, press manual button 5 times within 2 second as well, the white LED will flash!  "5-click protection" can protect the battery from being activated when you do not want or do not use it. No more firing in your pocket!

lithium battery protection: It has strengthened short circuit protection and over discharge protection based on eGo-T batteries and there is a device inside to prevent overcharging.
