Features Of The Caliburn A2

  1. Compact and Lightweight Design: The Caliburn A2 is nearly identical in size to the original Caliburn and slightly smaller than the Caliburn G. It measures 110.1 mm x 21.3 mm x 11.7 mm and weighs 33 grams with a full pod, making it compact and lightweight for easy portability. The device is available in six colors, including standout options like bright orange and iris purple, allowing users to choose a style that suits their preferences.
  2. Design Upgrades: Notable design upgrades include a Type-C charging port and a large window on the front for easily checking juice levels. The mouthpiece has also been redesigned to be thinner and smoother, offering a modern look and a pleasant hand feel. These improvements enhance both the functionality and aesthetics of the A2.
  3. Pro-Focs Technology: The A2’s pods are redesigned and feature Pro-Focs technology, which focuses on delivering great flavor. The flavor from the A2 is clean and crisp, especially with 50/50 juices, and the coils last for around 20 mL of juice. While some juice may get into the mouth after multiple refills, the overall performance remains impressive, providing a satisfying vaping experience.
  4. Battery Life and Charging: The 520 mAh battery of the Caliburn A2 offers around 3 mL of use per charge. It charges via a Type-C port in about 52 minutes, though Uwell claims a 90% charge can be achieved in 35 minutes. The LED battery indicator helps monitor the battery status, with green indicating 60-100%, blue for 30-60%, and red for 0-30%. This ensures that users are always aware of their battery levels, preventing unexpected shutdowns.

How To Use The Uwell Caliburn A2?

To effectively use your Uwell Caliburn A2, start by charging it using a Type-C cable (not included). The LED indicators will show battery levels: Green (60-100%), Blue (30-60%), and Red (0-30%).

When refilling, remove the mouthpiece by pushing on the flat side. Fill the pod through the red-marked hole at the top, then reattach the mouthpiece. Let the pod sit for 5 minutes to prime the coil.

To activate the device, press the fire button five times quickly to turn it on or off. You can choose between auto-draw activation (simply inhaling through the mouthpiece) or button activation (pressing the fire button while inhaling).

Monitor juice levels through the window on the front of the device. Replace the pod when flavor diminishes or after using approximately 20 mL of juice.

Following these steps will help you effectively use and maintain your Uwell Caliburn A2 pod system.
