Main description: The Twist Variable Voltage battery is the upgrade version. We 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 can work with eGo-C/eGo-T/eGo/510/510-T/Protank/Davide etc atomizers!
A fully charged Twist variable voltage battery can support you 10 hours, 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!
