With Uwell Pro-Focs flavor adjustment technology, Caliburn GK2 will give you the best vaping experience.

The Uwell Caliburn GK2 Pod Vape features a more interactive experience for users. The device shows different colors at different power levels. It also vibrates to indicate different working states like low voltage, over time, open circuit, and cartridge install.

During a vape, a shimmering green light indicates battery quantity is more than 60%. When it turns blue it marks the battery quantity is between 30% - 60%. Anything less than 30% is shown by a red sign. An 8 second vape cut off works when the lights shimmer green 5 times and send out 2 vibration that means you’re over vaping it and you should stop for a while. And when the red light blinks constantly and the battery vibrates three times, then it is time to recharge it.

According to the user manual, the lights also indicate the following potential safety issues:

  • Short circuit protection. Yellow flicker x 4, vibration x 4
  • Low voltage protection. Red flicker x 10, vibration x 3
  • Overtime protection. Green glimmer x 5, vibration x 2
  • Open circuit indication. Blue flicker x 3, vibration x 2

The lights will glint when the pod/cartridge is plugged or unplugged from the device.

With the precise airflow adjustment wheel, vapers can get precise airflow and create a looser or a tighter inhale whatever they want.

The top filling design is the easiest way to refill without pulling out the pod cartridge. Fast and convenient. The transparent window design provides an easy way to check the e-liquid level at any time.
