Uwell Caliburn AK3 Pod Kit

Uwell Caliburn AK3 Pod Kit

A 15-minute full charge and a draw-and-go setup make the Uwell Caliburn AK3 one of the simplest refillable pod kits to live with. It runs a 520mAh battery at a fixed 13W, takes 2ml Caliburn A3 pods with a 1.0ohm mesh coil, and fires the moment you inhale, with no wattage to set and nothing to learn.

A silicone lanyard makes it wearable, and the logo-shaped light shows your battery at a glance. It suits ex-smokers and ex-disposable users who want a tight MTL draw without the fuss, and it sits in the Refillable Pod Kits range. Fill a pod with your own Nic Salts, pick a colour, and go.

Why vapers choose this:

• Charged in 15 minutes. USB-C fast charging fills the 520mAh battery quickly, so a short top-up gets you through the rest of the day.

• Nothing to learn. Fixed 13W output and draw activation mean you just fill and inhale, no menus or settings.

• 1.0ohm mesh pods deliver a tight, cigarette-style MTL draw that suits nic salts.

• Wearable design. The included lanyard lets you hang it round your neck so it is always to hand.

• Logo light shows the battery at a glance: green for high, blue for medium, red for low.

Uwell Caliburn AK3 Features

Full Charge in 15 Minutes

The headline feature is the charging. Over USB-C, the 520mAh battery goes from low to full in around 15 minutes, far quicker than most pod kits. If you forget to charge overnight, a quick top-up before you head out is enough. For a compact everyday pod, that speed makes a real difference.

Made to Be Simple

There is no screen, no wattage menu, no modes, and no fire button. The AK3 runs a fixed 13W and fires instantly the moment you inhale, which makes it one of the easiest refillables to pick up if you are transitioning from disposables. Pair it with a bottle from the 10ml e-liquids range and you are vaping in seconds.

A Tight MTL Draw

The 1.0ohm FeCrAl mesh coil built into every Caliburn A3 pod gives a firm, cigarette-style mouth-to-lung inhale, the kind most ex-smokers are after. Uwell's flavour-tuning tech helps the pod carry taste cleanly, which is a big part of why the Caliburn range earned its reputation. It pairs best with nic salts and 50/50 e-liquid.

Refill Without the Mess

Filling is a top-fill job through the mouthpiece, so there is no need to pull the pod out. Uwell reworked the pod structure to cut down on leaks, and a clear check window lets you see your e-liquid level and the minimum line at a glance. A quick, tidy top-up every time.

Wearable and Pocket-Sized

At just 12mm thick and 35.8g, the AK3 slips into any pocket, and the included silicone lanyard lets you wear it round your neck so it is never buried in a bag. The logo-shaped light on the body pulses when you draw and shows your battery level, and you can switch that animation off if you prefer. A neat, portable daily carry from the MTL Vape Kits side.

How to Set Up the Uwell Caliburn AK3

First fill takes a minute or two. Let the pod soak before you draw.

1. Snap the black plastic mouthpiece off the pod by pushing it flat (you do not need to remove the pod from the device to do this).

2. Insert your e-liquid bottle nozzle into the red fill port (never the center airflow hole).

3. Fill the 2ml pod, watching the clear check window so it stays above the minimum line, then snap the mouthpiece back on.

4. Stand the device upright for five to ten minutes so the mesh coil wicks fully. Firing a dry coil will instantly ruin it.

5. Charge over USB-C if the logo light shows the battery is low (red). A full charge takes about 15 minutes.

6. Simply inhale on the mouthpiece to vape.

What's in the Uwell Caliburn AK3 Box

The kit includes:

• The Caliburn AK3 device,

• two 1.0ohm Caliburn A3 pods (one pre-installed, one spare),

• a wearable silicone lanyard,

• and a user manual.

As a bonus, Pirate Vapes includes a free 10ml e-liquid with this kit (selected at checkout). (Note: To cut down on packaging waste, Uwell does not include a USB-C charging cable in the box. You will need to use a standard Type-C phone charger).

Made for the Uwell Caliburn A3 Pod System

The AK3 runs on Uwell Caliburn A3 pods with the integrated 1.0ohm mesh coil. Both pods in the box are the same, and it is also compatible with the side-filling Caliburn A3S pods if you prefer that fill style, giving you a little flexibility down the line.

Worth knowing: these are Caliburn A3 series pods specifically. They do not fit other Uwell kits like the Caliburn G series, or any other brand. Stick to A3 or A3S pods, and you are covered. You can browse more replacements in the Uwell Coils range.

About Uwell

Uwell built its name on the Caliburn, one of the most popular pod kits ever made and a device that helped set the standard for simple, flavour-focused MTL vaping.

The brand's flavour-tuning technology is the thread that runs through the whole Caliburn line, and the AK3 is a stripped-back take on it: fast charging, a wearable design, and that signature tight draw, without a screen or settings to get in the way. For a lot of vapers coming off disposables, a Caliburn is the natural first refillable, and the AK3 is about as easy as they come.

Stock Up and Save

A refillable kit like this pays off quickly. Filling your own 2ml pods costs far less than repeat-buying prefilled devices, and keeping a spare pod on hand means you are never stuck when a coil fades.

Pirate Vapes dispatches every order the same day when it is placed before 4 pm. All stock is TPD compliant, sold through an age-verified checkout, over-18s only, with Free Pirate Post on orders over £40.

Conclusion

The Uwell Caliburn AK3 is a simple, fast-charging pod kit built for anyone who wants a tight MTL draw without the fuss. The 15-minute charge, fixed 13W output, wearable lanyard, and 1.0ohm mesh pods make it an easy step off disposables or a reliable everyday carry.
