The Ego K 1100 mAh battery is very sleek with its laser engraved designs in black and silver. Different color options are available. 

A fully charged eGo K battery works at 4.2v, and the voltage will decrease as battery power decreases. The battery will stop working at 3.0v and will need to be recharged. The battery comes with overcharging protection and a 5-click on/off function. Press the button 5 times within 2 seconds to turn the battery off and on. 

Please use only the 420 mAh Ego Fast USB Charger or the Joyetech Ego charger for Ego-Q and Ego-K battery. You may use our wall adapter to charge battery in a standard wall outlet. It takes approximately 3 hours to fully charge the battery.
