Uwell Caliburn AZ3 Pod Vape Kit

Uwell Caliburn AZ3 Pod Vape Kit

Pocket-sized at 68.9mm tall and 39.5g in the hand, the Uwell Caliburn AZ3 is a compact MTL pod kit built around a 750mAh battery and a 17W maximum output. It runs on Caliburn A3 refillable pods with a fresh U-Valve 3-step refill system and a ClearView juice window so you can see what is left before the coil dries out.

Powered by USB-C fast charging and auto-draw activation, this is a nicotine salt kit for ex-smokers, disposable switchers, and anyone shopping the Refillable Pod Kits shelf for something small, cheap to run, and easy to live with.

Why vapers choose this:

• The refill window actually works. The ClearView cut on the pod lets you eyeball the liquid level in a second, which is the single easiest way to stop burning a coil out early.

• Two coils, two draws. The 0.8Ω pod runs looser and warmer; the 1.0Ω tightens the draw for a firmer cigarette-style hit.

• Charges fast. 2A USB-C means the AZ3 tops up quicker than most pod kits in this class.

• Fits in a coin pocket. At 39.5g, it disappears into a jacket.

• Auto-draw only. No fire button, no accidental pocket firing, no learning curve for anyone stepping across from a disposable.

Uwell Caliburn AZ3 Features

3-Step U-Valve Refill

Uwell's 3-step U-Valve refill mechanism is the headline feature here. Open the port, drip your juice in, close it. The valve seals the airflow path away from the fill hole, which is where most pod leaks originate. If you have ever pulled a soggy kit out of a bag, you will notice the difference within a week.

ClearView Juice Window

That transparent strip down the side of the pod tells you exactly when to refill. Running a mesh coil dry for even a minute cooks it. Being able to glance at the pod and top up on time is the single cheapest way to make your pods last longer, and by extension keep your Nic Salts budget under control.

Breath-Pulse LED Indicator

The LED pulses in different colours as you vape. Green tier for a full battery, an orange middle, red when it is time to plug in. Simple, glanceable, and it means you never get caught mid-shift wondering how much charge is left. Small touches like this are why the Caliburn line has held its reputation for years.

0.8Ω and 1.0Ω Pod Options

The 0.8Ω pre-installed pod suits a slightly looser, warmer MTL draw and pairs well with 10-15mg salts. The 1.0Ω spare tightens the airflow noticeably and works best with 20mg Nic Salts for ex-smokers who want that firmer throat hit. Both are FeCrAl mesh, both hold 2ml, and both use the same pod slot.

Aluminium Alloy and PCTG Build

The device body is anodised aluminium, so it takes daily pocket knocks without the cheap plastic creak you sometimes hear on budget pod kits. The pod itself is PCTG, a plastic chosen for chemical resistance to sweetened juices. In practice, that means the pod does not cloud up or crack after a few weeks of citrus and menthol.

How to Set Up the Caliburn AZ3

Under two minutes from box to first draw.

1. Remove the pod from the device and peel the protective sticker from the base.

2. Snap off the black mouthpiece to access the top fill port.

3. Insert your bottle nozzle into the red silicone fill valve and fill the pod.

4. Snap the mouthpiece back on until it clicks firmly into place.

5. Pop the pod back into the device and leave it upright for 8 to 10 minutes.

6. Take short, gentle draws to start vaping without burning the coil.

What's in the Caliburn AZ3 Box

Inside the box, you get the AZ3 device itself, a pre-installed 0.8Ω FeCrAl mesh A3 refillable pod, a spare 1.0Ω FeCrAl mesh A3 refillable pod, a Type-C USB charging cable, and the user manual.

No e-liquid is included. Pair it with anything from the 50/50 E-Liquid range or a bottle of 10ml nic salt to get going.

Made for the Full Caliburn A3 Pod Family

The AZ3 accepts any Caliburn A3 refillable pod, and that includes A3, A3S, and AK3 pods on top of the AZ3 ones in the box. That is deliberate, since it means one pod supply covers you if you ever pick up a second Caliburn device from the Uwell Vapes range.

What does not fit: original Caliburn G, G2, G3, Koko, X, and any pre-A3 generation pods. Those use a different pod format entirely. If the pod on the shelf does not say A3 in the name, it will not click into an AZ3.

About Uwell

Uwell built the Caliburn line into one of the most recognisable pod-kit families in vaping, largely on the back of two things: consistent flavour delivery through their Pro-FOCS coil tuning, and pods that actually seal without leaking.

The AZ3 sits inside the newer ZEGA form factor, which is Uwell's answer to disposable-switcher demand: something as light and pocketable as a bar, but properly rechargeable, refillable, and legal to sell after the June 2025 single-use ban. Every AZ3 sold through Pirate Vapes is MHRA-notified, TPD-compliant UK-market stock.

Stock Up and Save

A single pod will typically see you through a week or so at moderate MTL use, sometimes longer if the pod stays sealed and the coil stays wet. A spare 2-pack of A3 pods sitting in the drawer means you never lose a day of vaping to a burnt coil.

Pirate Vapes ships every AZ3 order same-day when placed before 4 pm, tucked into padded packaging to survive the postal system. All hardware is age-verification-gated at checkout, over-18s only, and part of our wider Reusable Vapes selection. Free Pirate Post kicks in on baskets over £40.

Conclusion

The Caliburn AZ3 does exactly what a good pod kit should do in 2026. Small, quick to charge, refillable, cheap to run, and forgiving enough that disposable switchers can pick it up without a manual.

The U-Valve refill and ClearView window are the two upgrades that make this feel like a genuinely thought-out kit rather than another rebadged pen. Grab one from Pirate Vapes, pair it with a 20mg salt in your favourite flavour, and you have a daily driver for well under a tenner in ongoing costs a month.

FAQs

What nicotine strength should I use in the AZ3?

Nic salts at 10mg or 20mg work best. Freebase up to 12mg is fine in the 1.0Ω pod. Sub-ohm juice is not designed for it.

Is the AZ3 refillable or does it use prefilled pods?

Refillable. Both pods in the box are empty and take standard 10ml nic salt bottles.

How long does the battery last?

A 750mAh cell typically covers most vapers for a full day at moderate use. Heavy chain-vapers may want to top up at lunch.

Can I use my old Caliburn G3 pods in this?

No. The AZ3 only accepts A3-format pods (A3, A3S, AK3, AZ3). G-series pods use a different slot.

Why does my pod taste burnt?

Almost always dry wicking. Refill sooner using the ClearView window as your guide, and always let a fresh pod soak for a solid 8 minutes before the first draw.

Is the AZ3 legal to sell after the disposable ban?

Yes. It is rechargeable, refillable, and uses replaceable pods, so it sits outside the June 2025 single-use ban entirely.
