The UWELL Caliburn Air takes a slightly different approach from other Caliburn devices. Instead of adding a bigger screen, more buttons, or another menu to learn, UWELL has actually stripped things back.
The Caliburn Air weighs just 39g, uses draw activation, works with UWELL’s wider G Pod Platform, and gives you two output modes without needing a screen. You can even adjust the airflow by simply turning the pod around.
That makes the Caliburn Air pretty easy to use. It’s for people who like the Caliburn pod experience but don’t necessarily want all the controls that come with more advanced devices.
In this UWELL Caliburn Air review, we’ll look at how it works, what makes it different, which pods it uses, and who it’ll suit best.
TLDR;
- The UWELL Caliburn Air weighs only 39g, making it one of the lightest Caliburn devices.
- It has a 1000 mAh built-in battery.
- There’s no fire button or screen. You simply inhale to vape.
- You get WAVES Mode and STORM Mode for two different output styles.
- Switching modes is simple. Remove and reinsert the pod twice quickly.
- Airflow is adjusted by turning the cartridge around.
- It uses the newer GPP Alpha cartridge with a soft-touch TPU mouthpiece.
- It also works with the wider UWELL GPP cartridge family.
- It’s best suited to people who want a light, uncomplicated refillable pod without giving up useful options.
The Caliburn Air keeps the features you’ll actually use and removes the stuff you probably won’t.
What Is the UWELL Caliburn Air?
The Caliburn Air is a lightweight, refillable pod system from UWELL.
It sits inside the same Caliburn ecosystem as devices like the Caliburn G4 and Caliburn G5 series, but it’s built around simplicity rather than screens and advanced controls.
There’s no menu to work through.
There’s no wattage button to press every time you change something.
There isn’t even a fire button.
Instead:
- you inhale to activate the device
- you flip the pod to change airflow
- you remove and reinsert the pod twice to change output mode
That’s really the whole idea behind the Caliburn Air.
It’s still flexible enough to adjust, but it doesn’t feel like something you need to constantly manage.

The specs tell the story pretty clearly. This isn’t trying to be a miniature vape mod. It’s built to stay light, simple, and easy to carry.
39g Design: Why the Caliburn Air Feels Different
The first thing that stands out is the weight.
The Caliburn Air weighs only 39 grams.
That’s genuinely light for a refillable pod system, especially one carrying a 1000 mAh battery.
Weight might sound like one of those specs that doesn’t matter much until you actually carry a device every day. Then it matters a lot.
A lighter pod is easier to:
- keep in your pocket
- carry around at work
- take on short trips
- hold for longer periods
- keep as a second device
There aren’t many parts sticking out or extra controls taking up space either.
The design feels like UWELL started with one question: How much can we remove without making the device too basic?
That’s probably the best way to describe the Caliburn Air.
How Long Does the Caliburn Air Battery Last?
The UWELL Caliburn Air has a 1000 mAh built-in battery.
UWELL says it can provide up to three days of use under its own testing conditions.
Battery life will depend on:
- how often you vape
- which GPP cartridge you’re using
- whether you’re using WAVES or STORM Mode
- how long your draws are
- how open your airflow is
Someone taking occasional MTL puffs will obviously get much longer between charges than someone vaping heavily throughout the day.
So, rather than focusing too much on the three-day claim, the more useful takeaway is this: 1000 mAh is a decent amount of battery for a pod that weighs only 39 g.
That’s the balance UWELL is going for.
You’re getting reasonable battery capacity without turning the Air into a bigger or heavier device.
How Does the Caliburn Air Charge?
Charging is handled through USB Type-C at 5V/1A.
There’s nothing complicated here. Plug it in, charge it, and you’re ready to go again.
The charging rate isn’t as fast as some larger Caliburn devices, but that’s not really what the Air is built around.
It’s a smaller battery inside a very lightweight device, so the priority is portability rather than having the fastest charging system in the Caliburn range.
GPP Alpha Cartridge: The Main Upgrade
The GPP Alpha cartridge is probably the most important part of the Caliburn Air.
UWELL designed the Alpha cartridge around two things pod users care about a lot:
- keeping flavour more consistent
- making the pod last longer
UWELL’s own lab testing reports:
- 17+ refills for the 3 mL cartridge
- 25+ refills for the 2 mL cartridge
- 50 mL+ of e-liquid through the cartridge
These numbers come from UWELL’s own testing, so they shouldn’t be treated as a guarantee.
Your pod life can change depending on:
- the e-liquid you use
- how often you vape
- your puff length
- which output mode you use
- whether you let the pod run too low
- how well you prime a new cartridge
Still, the direction is useful.
UWELL clearly wants the Alpha cartridge to last longer before flavour starts dropping off.
That matters because replacement pods are one of the biggest ongoing costs with any refillable pod system.
Soft-Touch Mouthpiece
The GPP Alpha cartridge also uses a soft-touch TPU mouthpiece.
That might sound like a small detail, but it actually makes sense on a device like this.
The mouthpiece is the part you’re physically using every time you take a puff. If you’re carrying the Air all day and using it regularly, comfort matters.
Most pod mouthpieces use fairly hard plastic.
The softer TPU surface gives the Alpha cartridge a slightly different feel and fits nicely with the whole lightweight, comfortable design of the Air.
It’s not something that’ll completely change your vaping experience, but it’s the kind of detail you’ll probably appreciate more after using the device for a while.
WAVES Mode vs STORM Mode
The Caliburn Air gives you two output modes:
WAVES Mode
WAVES Mode gives you the smoother of the two outputs.
It’s designed for a steadier, more relaxed draw rather than hitting hard straight away.
This’ll probably make more sense if you:
- prefer smoother puffs
- vape regularly throughout the day
- don’t want a strong initial burst of power
- like a more balanced draw
STORM Mode
STORM Mode gives you a stronger initial output.
It feels more direct and punchier than WAVES Mode.
You might prefer STORM if you:
- want a stronger-feeling draw
- like quicker power delivery
- prefer a little more intensity from your pod
Neither mode changes the device into something completely different.
Think of them as two different ways the power gets delivered.
WAVES is smoother.
STORM is more immediate.
How Do You Change Modes on the Caliburn Air?
There’s no menu and no screen.
To switch between WAVES and STORM Mode, you simply:
- Remove the cartridge.
- Reinsert it.
- Repeat that quickly a second time.
That’s it.
The device then switches modes.
It might sound a little unusual at first, but it makes sense once you understand what UWELL is trying to do.
Adding a button would’ve added another control.
Adding a screen would’ve made the device more complicated and heavier.
Using the pod itself as the control keeps everything simple.
How Do You Adjust Airflow on the Caliburn Air?
The airflow works in a similar way.
There’s no airflow slider.
Instead, you remove the cartridge, turn it 180 degrees, and put it back in.
Each orientation gives you a different airflow setting.
One side gives you a tighter draw.
Flip the pod around and you’ll get a more open draw.
That makes the system very easy to use, but there’s one tradeoff.
You don’t get the fine adjustment you’d get from a proper airflow slider.
So if you’re the kind of person who likes making tiny airflow adjustments until the draw feels exactly right, something like the Caliburn G5 may suit you better.
If you just want a choice between tighter and looser, the Caliburn Air keeps things much easier.
Does the Caliburn Air Have Auto-Draw?
Yes.
The Caliburn Air is draw activated, which means there’s no fire button.
You simply inhale through the mouthpiece and the device activates automatically.
That’s one of the reasons it’ll probably feel familiar to people coming from disposable vapes or simpler pod systems.
There’s very little to learn.
Fill the pod, let a new cartridge soak properly, install it, and inhale.
For experienced Caliburn users, auto-draw also makes the Air a good grab-and-go device when you don’t feel like dealing with extra controls.
Which Pods Work With the Caliburn Air?
This is one of the device’s biggest advantages.
The Caliburn Air is compatible with UWELL’s G Pod Platform, or GPP cartridges.
That means you’re not buying a device that only works with one special new pod.
If you already use compatible GPP cartridges with newer Caliburn devices, the Air fits into the same broader ecosystem.
That makes replacement pods easier to find and gives you more options when choosing resistance.
Depending on the compatible cartridge you choose, you can move between:
- tighter MTL vaping
- slightly looser MTL
- lighter RDL vaping
That’s quite a bit of flexibility for such a simple device.
What’s the Best Pod for the Caliburn Air?
Higher-resistance GPP cartridges
These GPP cartridges generally make more sense if you want:
- tighter airflow
- lower-power vaping
- MTL use
- nic salt e-liquid
Lower-resistance GPP cartridges
These are usually better if you want:
- a looser draw
- warmer vapour
- more vapour production
- RDL-style use
- suitable freebase e-liquid
The included GPP Alpha cartridge gives you a good starting point, but having access to the wider GPP range means you’re not stuck with one vaping style.
What E-Liquid Should You Use in the Caliburn Air?
The right e-liquid depends more on the cartridge than the device itself.
That’s worth remembering.
If you’re using a higher-resistance MTL pod, nicotine salts or balanced freebase e-liquids will generally make more sense.
If you move to a lower-resistance GPP pod and a looser airflow setting, lower-strength freebase e-liquid may be the better fit.
What you shouldn’t do is assume every vape juice works equally well with every cartridge.
Always match:
- nicotine strength
- VG/PG ratio
- pod resistance
- airflow style
That’ll usually give you better performance and help the pod last longer.
Is the Caliburn Air Good for MTL Vaping?
Yes.
With the right GPP cartridge and the tighter airflow orientation, the Caliburn Air should make a good MTL pod vape.
MTL, or mouth-to-lung vaping, uses a tighter inhale similar to drawing through a narrower mouthpiece.
That’s the style many pod users prefer, especially with higher-resistance cartridges.
The Air’s simple design suits MTL particularly well because you don’t need lots of power or complicated adjustments.
Can the Caliburn Air Do RDL?
Yes, within reason.
A lower-resistance compatible GPP cartridge and the more open airflow position can give you a restricted direct lung, or RDL, draw.
Just keep expectations realistic.
The Caliburn Air isn’t a high-powered pod mod.
It’s a small, lightweight pod designed mainly around efficient everyday use.
So it can move toward RDL, but it’s not trying to replace a larger high-output device.
Caliburn Air vs Caliburn G5 Lite
The Caliburn Air and Caliburn G5 Lite actually make an interesting comparison because both aim to keep pod vaping fairly simple.
But they go about it differently.
| Feature | Caliburn Air | Caliburn G5 Lite |
| Battery | 1000 mAh | 1600 mAh |
| Weight | 39 g | Larger/heavier |
| Screen | No | No full screen |
| Activation | Auto-draw | Simple operation |
| Airflow | Flip the pod | Adjustable airflow |
| Output modes | WAVES and STORM | Automatic pod-based output |
| Pod compatibility | GPP | GPP |
| Main strength | Lightweight simplicity | Larger battery |
| Best for | Easy pocket carry | Longer runtime |
Choose the Caliburn Air if:
- you want the lighter device
- compact size matters most
- you like auto-draw
- you want WAVES and STORM modes
- you prefer very simple airflow control
Choose the G5 Lite if:
- battery life matters more
- you don’t mind carrying a slightly larger device
- you want more airflow adjustment
- you want stronger performance with lower-resistance pods
The Air isn’t necessarily trying to beat the G5 Lite.
They’re aimed at slightly different people.
Who Should Buy the UWELL Caliburn Air?
The Caliburn Air makes the most sense for:
- people who want an extremely light refillable pod
- existing Caliburn users who already have GPP cartridges
- people who prefer auto-draw
- users who don’t care about having a screen
- beginners who want something easy to understand
- experienced users looking for a lightweight second device
- people who value portability more than manual wattage control
The Air’s biggest strength is that you don’t really need to think about it much.
Fill it.
Choose your airflow.
Pick WAVES or STORM.
Then vape.
Who Might Prefer Another Caliburn?
The Air won’t be the best Caliburn for everyone.
You might prefer something like the Caliburn G5 or G5 KOKO if you want:
- a larger battery
- a screen
- exact battery information
- manual wattage adjustment
- finer airflow control
- more settings
- a higher-powered setup
That’s not really a weakness of the Air.
It’s just a different product.
UWELL has clearly designed it for people who’d rather have less to manage, not more.
