The Uwell Caliburn GK3 pod kit is a pocket-friendly vape, ideal for new and seasoned vapers alike. It contains a built-in 900mAh battery, which offers plenty of vaping before needing to be recharged. Delivering a 5-25W power output range, the GK3 is a solid option for both MTL (Mouth To Lung) and RDTL (Restricted Direct To Lung) vaping. This kit is compatible with the refillable Caliburn G3 pods and two 2ml pods are also included to help get you started.

  • Dual Airflow
  • 2ml Refillable Pods

  • Built-In Coils

The GK3 boasts single-button operation and you can get started with five quick clicks. When unlocked, vape by either pressing the button or just inhaling on the mouthpiece. The device’s smart, built-in chipset recognises your coil’s resistance and selects the best power output automatically, helping your pods last longer. If you’re looking for extra customisation, you can also set a power level manually. Remove the pod, rotate it and re-insert it to take advantage of the dual airflow design and experience a tighter or looser inhale. However you decide to vape, keep track of power and battery life easily with the GK3’s built-in OLED display.

The Caliburn G3 pods hold up to 2ml of e-liquid and boast a simple top-filling design. Refilling your pod is as easy as lifting off the mouthpiece — you don’t even have to remove it from your device. Their built-in coil design cuts down on maintenance, as you can just replace the whole pod when the coil inside needs changing. Want to switch between an RDTL and MTL inhale? Simply swap between the 0.6 Ohm and 0.9 Ohm pods, both of which will work best 50% VG e-liquids and higher PG vape juice.

Grate flavour. (02 June 2024)

Much better flavour over the g2/gk2.
The screen is a good addition and adjustable wattage is nice.

By Jamie from Devon

Battery poor, no major improvements (31 January 2024)

Poor battery life (no improvement over the AK3 which only has 500mah). Feels/looks quite cheap and is quite bulky considering it has no real performance improvements over similar versions. I wouldn’t recommend for the price.

By Chabz from London

By far the best GK (30 January 2024)

Very confused why people are dissing this device, when it is a lot better then any previous GK device, bigger battery for starters. Its so light and it has such a smooth finish and not at all slippery. The massive display has all the basic information from the wattage, puff counter, resistance and just because it is big it doesn't have a big impact on the battery life. And like with the G3, the pods are fantastic. That's where probably the biggest improvement is with this series. They last at least three times longer, and they boost the flavour as well. I do prefer the 0.6 over the 0.9. I can not say anything bad about this device, except that the top filling pods are a bit fiddly, but you can get use to that. I own several different uwell devices and this one with the G3 are my absolute favourite!

No real improvement (09 January 2024)

Still using the 900mah battery with no real big improvement on the coils or pods. The only upside is the adjustable wattage which make a slight difference but this is marginal

Another one… (02 January 2024)

Used to love the Caliburn range then they just keep bringing out the same stuff with no real improvements. Is Uwell the new Smok?
