Uwell Caliburn G3 | Review

Does the Caliburn G go from Great to Grand?

The Uwell Caliburn G3 is the latest pod vape in the popular Caliburn series. 

Building on previous models like the Caliburn and Caliburn G, the G3 brings noticeable upgrades to power, battery life, and performance.

At first glance, the Caliburn G3 looks very similar to past versions with its slim, rectangular design. But it now packs a 900mAh battery and adjustable wattage up to 25W. 

Other upgrades include a new OLED screen, adjustable airflow via pod rotation, and larger 2.5ml pods with easy side-filling. 

The kit includes two of Uwell’s new G3 pods: a 0.9Ω and a 0.6Ω mesh pod.The Uwell Caliburn G3 is available in 6 colors: Silver, Gray, Black, Red, Green, and Blue.

Design & Build Quality

At first glance, the Caliburn G3 looks very similar to the previous G2 model, featuring the same slim and rectangular shape. But it’s slightly larger in all dimensions, measuring 115.5mm tall, 24mm wide, and 13.9mm thick. 

Thankfully, that size bump accommodates the larger 900mAh battery (compared to G2’s 750mAh).

Despite the size increase, the G3 remains lightweight and comfortable to hold. Weighing only 47g, it’s easy to palm or slip into a pocket. The aluminum alloy body feels very durable in hand with no rattles or cheap plastic feel.

The color options have been slightly tweaked also. They are muted metallics, including silver, gray, black, red, green, and blue. 

We’ve got all the versions in for review, and I particularly love the new deep Green and Blue variations. They all look clean and understated, with an excellent matte finish that resists fingerprints well. 

The pods connect securely via strong magnets. They snap cleanly into place with no wiggle. The magnetic connection is just right – not too loose but easy to remove.

The adjustable airflow is now handled by rotating the pod 180 degrees. It’s simple but does limit you to just two airflow settings rather than the adjustable wheel on previous pods.

Uwell Caliburn G3 Juice Window

One of my favorite design elements is the e-liquid window on the mod. It uses a unique cut-out shape on both sides of the battery housing to get a clear, unobstructed view of the juice level.

The fire button sits flush with the body and has a grooved texture for easy pressing. 

The most significant upgrade on the Caliburn G3 includes a small but bright 0.96″ OLED screen. 

For such a small screen, it packs a lot of info from Output, Resistance, Charge, Puffs, and Fire Mode. 

It’s a little too cramped for my liking. Still, it’s what the Caliburns have been missing, along with the fully adjustable wattage that’s now present.

Uwell Caliburn G3 USB Port

As with previous models, the USB-C charge port sits flat on the base. It supports 2A fast charging.

Overall, the Caliburn G3 has excellent build quality with an understated, minimalist look. I think the new color schemes give it a more sophisticated air than previous models, and the OLED screen brings a modern touch. 

Despite these minor changes and the size increase, the design stays true to the Caliburn series.

Features & Functions

The Caliburn G3 packs a wide range of features and functionality for a pod system. 

The most noticeable is the new 0.96″ OLED screen. It displays wattage, battery level, resistance, puff count, and firing mode in a compact space.

That adjustable wattage is another significant upgrade, ranging from 5-25W. There are no preset power levels, and it can be adjusted in 1W increments. The output automatically caps based on the coil resistance for safety.

Along with the wattage control, there are multiple firing modes. You can choose button firing, auto draw, or a mode that enables both. The auto-draw activation is instant, similar to previous Caliburn devices. 

The Caliburn G3 only has one button for making adjustments, so it can be a little fiddly. Here’s what you need to know:

  • On/Off – 5 clicks of fire button
  • Fire Mode Adjustment – 2 Clicks of the fire button to rotate through the settings. The screen also shows the settings in the following order: 
  1. Locked (locks button) 
  2. Locked (locks auto-draw, only manual firing)
  3. Auto (both active)
  • Power Adjustment – 3 clicks of the fire button. The wattage value will flash, and then each button click will increase the value by 1W. Wait 3 seconds or take a draw to confirm selection.
  • Clear Puff Counter – 4 clicks of the fire button

Learning the different click combos takes some memorization but is pretty straightforward and allows full control.

Charging has been upgraded to a Type-C USB port. It supports a fast 2A charging rate and takes about 45 mins to fully recharge the 900mAh battery from empty. 

The G3 does have adjustable airflow, but it’s limited. It’s now handled by rotating the pod, with two airflow settings available. It’s simple but is a slight step back from the Caliburn G2’s pods.

Additional features include short circuit protection, over-time vape protection, no atomizer detection, and low battery protection.

Uwell Caliburn G3 Pods/Coils


The Caliburn G3 introduces a new pod system with fixed, non-replaceable coils. 

While it feels like a step back from the replaceable coil pods used in the Caliburn G2 and other models. Uwell claims they deliver better flavor and are more leak-resistant.

Two pod resistances are included in the kit:

  • 0.6Ω pod (RDTL)
  • 0.9Ω pod (MTL)

Both contain FeCrAl alloy mesh coils, according to Uwell.

There is also a 1.2Ω MTL pod available.

These pods have a 2.5ml capacity, are entirely enclosed, and now feature a side-fill port. 

The side-fill port works well with no flooding or gurgling issues for me. The silicone plug makes a tight seal. The fill hole is reasonably sized for easy refilling. 

Uwell will also make 2ml TPD CRC pods featuring the snap-off mouthpiece and top-fill system. These will be the only ones available in the EU, but both should be available in the US if you prefer that style.

The pods connect solidly with the strong magnets, and the device gives haptic feedback (vibration) when the connection is made.

While the airflow is not adjustable, you can rotate the pod 180 degrees to switch between two airflow settings. 

The pods themselves have different-sized inlet holes on either side to allow a tighter or looser draw. 

The new G3 pods seem to have good longevity. Both lasted around 2 weeks for me before the flavor started to degrade. 

Overall, the new pods deliver great flavor and coil life and improved leak resistance. I do miss top-fill and the replaceable coils though.

Sadly, the G3 is not compatible with previous Caliburn pods. This is a bit of a fail by Uwell, in my opinion.

I understand they wanted to go in a new direction with the pods, but surely they could’ve kept them the same size to be cross-compatible and better for users.

When it comes to vaping performance, the Caliburn G3 delivers an outstanding experience.

In my opinion, the flavor production is better than previous Caliburn kits – especially with the 0.9Ω MTL pod.

Starting with the 0.9Ω pod, the flavor is fantastic, right up there with the best MTL pods. 

I’ve been using the Vaporesso Luxe X Pro with 0.8Ω pods as my daily driver, and the G3’s MTL pod is definitely on par.

It brings out the nuanced notes in complex e-juices. The draw is smooth yet sufficiently tight for that satisfying MTL inhale. 

I don’t notice too much difference in the airflow when it’s rotated 180 degrees. Still, it does cover a tight/medium MTL and medium/loose MTL draw.

I’m sure that would satisfy most MTL vapers, but I’d still like to have seen full airflow control.

The 0.9Ω worked well with both freebase and nic salt juices. It still wicked fine with a 70VG juice with no signs of a dry hit.

The maximum wattage for the 0.9Ω pod is 15W, and it really sings at the setting, delivering a warm and saturated vape. The flavor production was equally as good down to about 13W, with just a cooler vape.

The throat hit delivered is perfect in the 13-15W range with 20mg nic salts.

After 2 weeks and about 20 refills, the 0.9Ω pod is still going strong with minimal drop in flavor and vapor production.

The 0.6Ω pod is best suited for restricted DL or loose MTL vaping. 

I found the flavor and vapor production excellent at the recommended 25W setting. However, any lower, and it did mute the flavor a little. 

The 0.6Ω pod also wicked well with 70VG juice, with no dry hits.

The airflow gives you a range of loose MTL to what I would classify as a very restricted DL.

While this pod is great for those that like a looser draw. It won’t satisfy those wanting a true DL draw.

But then it’s not really the device for that, and the 2.5ml capacity wouldn’t last long.

It does produce excellent amounts of vapor, and it’s a warm and saturated vape. 

I feel the 0.9Ω is just better suited to the G3 device.

Both the auto-draw activation and manual button firing work flawlessly. The hits come on instantly with no delay.

The battery life has improved markedly from earlier Caliburn devices. I could go 1-2 days between charges with moderate use – impressive for the small size. 

Charging is super fast, thanks to the 2A max USB-C charging rate. The battery reached a full charge in around 40 mins, give or take.

The Caliburn G3 delivered everything I wanted out of a new Caliburn. A sleek design with adjustable wattage, an OLED screen, a larger battery, and improved flavor. 

The only thing it’s missing is the full adjustability of airflow.

Uwell Caliburn G3


I can confidently say the Uwell Caliburn G3 is my favorite of all the Caliburns. 

It now competes with all other top pod vapes for features and delivers when it comes to performance.

The upgrade to a 900mAh battery, OLED screen, and adjustable wattage with a 25W max output is awesome. As is the overall build quality and new sophisticated colors.

Surprisingly, the flavor production from the new G3 pods was the most significant improvement. 

Flavors shine through beautifully on the 0.9Ω pod, while the 0.6Ω pod chucks clouds without compromising on richness. 

Sadly, it’s not all positive. As the airflow and fill methods have been simplified from the G2.

However, even with the cons like fixed coils, the Caliburn G3 still outperforms most rivals when performance counts, especially for MTL vapers who value flavor and the new 0.9Ω pods.




The Caliburn G3 is a significant step up from previous Caliburns. The increased battery life, OLED screen, and fully adjustable wattage make it the best Caliburn on offer. While the new pods do bring fantastic flavor and vape performance - it is at the sacrifice of replaceable coils and fully adjustable airflow. However, the G3 is still at the front of the pack for pod vapes - Highly recommended.
