This coil variety empowers vapers to tailor their experience according to their preferences.

Battery Power and Charging
With a built-in 720mAh battery, the Caliburn AZ3 Kit ensures extended vaping sessions with a maximum 16W output. Its draw-activated firing system adds convenience and simplicity. In contrast, the Caliburn GZ2 Kit comes equipped with an 850mAh battery, offering up to 18W output. Both devices retain the ease of draw-activated firing, and recharging is a breeze through their shared Type C USB ports.
