This is the Genuine JoyeTech eGo-C Twist 900 mAh Battery.
The Joye eGo-C Twist is one of the most popular new e-cigarettes for a reason. The Twist combines advanced variable voltage technology, simple operation and the familiarity of the eGo e-cigarette.
The eGo Twist lets you custom tune your vaping experience by selecting the output voltage from 3.2v to 4.8v. Set the voltage higher for a hotter vape or high resistance cartomizers, or turn the voltage down for a cooler vapor or low resistance cartomizers.
Using the Twist is simple, even with this advanced technology. Simply turn the dial at the bottom of the device to one of the marked voltage settings, or something in between to suit your tastes.
This is a genuine Joye product which means this is a high-quality product. Genuine Joye also means maximum compatibility with 510 and eGo cartomizers.
