UWell Caliburn G2 vs. Caliburn G

UWell has made more than a few fantastic vape devices over the last few years, and they’re determined to continue that trend with the latest model in the popular Caliburn series: the Caliburn G2. Brand new for 2022, this innovative device comes with key improvements over its predecessor, designed to give users even more control over their vaping experience.

What can you expect from the Caliburn G2 if you’re used to the previous model? And will it be for you if you’ve never owned a Caliburn before? Read on to find out. We’ll cover the key differences between these two devices and answer some common questions so that you can make an informed choice about the products you use.

What’s New for the Caliburn G2?

One of the most notable new features on the Caliburn G2 is the updated cartridge—which now holds 2mL of e-liquid (instead of 1.6mL for the Caliburn G cartridge). It’s also been designed to include a progressive airflow adjustment feature, giving you better command over your draw and resulting cloud size.

Another nice upgrade is the addition of an e-liquid window on both sides of the device, which makes checking to see how much e-liquid is left easier than ever. The Caliburn G2 also comes with a bigger battery—750 mAh vs. 690 mAh for the Caliburn G.

Finally, the G2 has a brand-new haptic feedback feature that causes the device to vibrate during key stages of its operation. The vibration helps users know when they have successfully performed tasks like inserting new pods or connecting the device to a charger. It also warns users about short-circuits, alerts them when they have taken particularly long draws, and more. To see the full list of things that can activate the G2’s haptic feedback, see “Why does my Caliburn G2 vibrate?” in the FAQ at the bottom of this post.

What Stayed the Same from the Caliburn G?

UWell seems to believe in the old adage, “if it ain’t broke, don’t fix it”. They’ve left the best parts of the Caliburn G alone—it’s still a slim, low-profile device that offers both button and draw activation and up to 18W of output.

The Caliburn G2 is just ever-so-slightly larger, but we’re talking about a difference of just a couple millimetres here. You’ll get used to it in no time.

Frequently Asked Questions about the UWell Caliburn G2

How does the progressive airflow adjustment feature on the Caliburn G2 work?

The Caliburn G2 cartridge comes with a wheel that allows you to adjust the airflow simply and smoothly. The Caliburn G also allows you to adjust the airflow, but doing so requires you to rotate the cartridge itself.

Is the Caliburn G2 compatible with Caliburn G coils?

The Caliburn G2 is not compatible with replacement coils for the Caliburn G. You’ll have to use replacement coils made specifically for the Caliburn G2.

How long does charging the Caliburn G2 take?

Fully charging the Caliburn G2 with the supplied charger takes approximately 25 minutes.

Why does my Caliburn G2 vibrate?

The Caliburn G2 provides haptic feedback via a vibrating mechanism that activates whenever:

  • You insert a pod
  • The battery is almost dead
  • You puff for longer than 8 seconds
  • You connect the device to the charger
  • The device is finished charging
  • The device is about to short-circuit

Is my Caliburn G2 supposed to vibrate continuously while charging?

Some users have reported their Caliburn G2 device vibrating unexpectedly when using non-standard chargers. To avoid this possibility and prevent potential battery damage, always use the charger supplied along with your Caliburn G2.
