Uwell Caliburn A2S (Side Fill) Replacement Pods

Uwell Caliburn A2S (Side Fill) Replacement Pods

1.2ohm mesh coil, 2ml of e-liquid, and a side filling port that keeps the refill where it belongs. The Uwell Caliburn A2S replacement pods are the refillable cartridges made for the A2S kit, each one carrying a pre-installed mesh coil sealed inside a clear pod you can actually watch fill. Sold as a pack of 4. 

They pull a tight MTL draw, take nic salts or 50/50 juice happily, and snap on with a magnetic connection. When the flavour drops off, you fit a fresh one. Some of the steadier Replacement Pods in the whole Caliburn family, honestly.

Why vapers choose this:

• The 1.2ohm mesh coil runs a genuine cigarette-style draw, which is exactly what most people used to a tight cigarette-style draw or an older top-fill pod are after, and the raised surface area of the mesh keeps flavour clean rather than muddy.

• Side filling means less mess. Pop the silicone stopper, drip in your juice, seal it back up.

• The pod is clear, so you can see your level and top up before it runs dry and starts tasting burnt.

• Magnetic fit. No threads, no clicking it in wrong.

• Works across three Caliburn kits, which is handy if you own more than one Uwell device or fancy pairing it with 50/50 E-Liquids at different strengths.

Uwell Caliburn A2S Replacement Pods Features

The 1.2ohm Coil Does the Heavy Lifting

Every pod arrives with a 1.2ohm Meshed-H coil already fitted. Higher resistance than the older 0.9ohm top-fill pod, which gives you a tighter, cooler draw and a slower burn. Mesh heats evenly across a bigger area, so the flavour lands crisp from the first pull. Pro-FOCS wicking sits behind it.

Fills From the Side, Stays Put in Your Pocket

Ever had a pod leak through your jeans? The A2S answers that with a silicone bung on the side. Twist it open, fill, twist it shut. Reviewers who found the top-fill version prone to seeping have reported the sealed side port holds firm, even carried upside down. Small design tweak, real difference.

Watch It, Don't Guess

The pod body is transparent for a reason. You can see the juice level at a glance and refill before the wick dries out. A dry wick is what causes that harsh burnt hit, so keeping the pod topped up is the cheapest way to make each one last. Simple habit, better vape.

Built for Salts and 50/50

At 1.2ohm, this pod is happiest with thinner liquids. Reach for Nic Salt E-Liquids or a balanced 50/50 blend rather than thick high-VG cloud juice. Thick liquid struggles to wick through at this resistance, and you will feel it as dry hits within a few draws.

No Buttons, No Settings

There is no airflow ring and no wattage to set. The A2S device reads the pod and fires up to 15W on its own. You fill, you inhale, it works. For anyone who just wants a device that behaves without fiddling, that is the whole appeal.

One Resistance, and That Is the Point

The side-fill A2S pod comes in a single build: 1.2ohm. There are no other resistances to weigh up here, which keeps the choice easy. If you specifically want the warmer, looser 0.9ohm draw, that lives in the top-fill A2 pod instead, and both fit the same devices. Either way, you are in tight MTL Pod Kits territory rather than sub-ohm clouds.

• 1.2ohm Meshed-H: tighter, cooler MTL draw, longer coil life, up to roughly 15W

How to Set Up the Uwell Caliburn A2S Replacement Pod

Quick swap. Under two minutes.

1. Lift the used pod off the battery. The magnets release with a gentle pull.

2. Ease out the silicone stopper on the side of the fresh pod to expose the fill port.

3. Fill with 50/50 e-liquid or nic salt, holding the pod at a slight angle and leaving a small air gap near the top so it does not overfill.

4. Press the stopper back in firmly until it sits flush and sealed.

5. Let the pod stand upright for a full five minutes so the wick soaks through completely before the first draw.

6. Take two or three gentle draws with no rush, then vape as normal. Starting soft protects the fresh coil.

What's in the Uwell Caliburn A2S Replacement Pods Box

Four side-fill pods, each with its 1.2ohm coil already installed. That is the lot. No e-liquid, no battery, and no device, so you will need your own Caliburn kit and a bottle of juice to get going.

Made to Fit the Caliburn A2 Series

These pods drop straight into the Pod Kits they were designed for: the Caliburn A2S, the Caliburn A2, and the Caliburn AK2. All three share the same magnetic pod platform, so a pack of A2S pods covers any of them.

What they will not fit is anything outside that trio. Not the original Caliburn. Not the KOKO. Not the G, G2, or G3. Each of those runs its own separate pod design, so check the name on your device before you buy.

About Uwell

Uwell built its name on the Caliburn line, and the A2S is where the series picked up side filling. Earlier Caliburn pods filled from the top, which worked but occasionally leaked liquid. The A2S kept the Pro-FOCS wicking that made the range known for flavour, then moved the fill port to a sealed side opening to cut down on mess.

It is a small, sensible evolution rather than a reinvention, and it is why the Caliburn name still turns up in so many pockets. See the wider Uwell Range for the kits these pods belong to.

Stock Up and Save

Think about how you actually vape. A pack of four side-fill pods usually carries a daily MTL vaper through most of a month, sometimes longer on lighter days, and sweeter liquids will shorten that as residue builds. Grabbing two packs now means you are never caught without a spare when the flavour fades on a Sunday night.

Every order from Pirate Vapes ships same day when placed before 4 pm. All stock is TPD compliant with an age-verified checkout, strictly over-18s only.

Conclusion

The A2S side-fill pod is the tidy, low-effort way to keep a Caliburn A2S, A2, or AK2 running. One resistance, a clear body, a sealed side port, and a coil that gives a clean MTL draw with salts or 50/50 juice.

If your kit still fires and you just want a fresh pod, this four-pack is the straightforward fix. Browse more Vape Accessories and the full lineup at Pirate Vapes.

FAQs

Which devices take the A2S pod?

The Caliburn A2S, Caliburn A2, and Caliburn AK2. All three use the same magnetic pods, so one pack works across the lot.

What resistance is the A2S pod?

1.2ohm, and that is the only option for the side-fill version.

Can I use the older top-fill pod in my A2S?

Yes. The 0.9ohm top-fill A2 pod fits the same devices if you want a warmer, slightly looser draw. It just fills from the top instead of the side.

What e-liquid should I put in the A2S pod?

Stick to 50/50, high-PG, or nic salts. Thick high-VG juice will not wick properly at 1.2ohm and you will get dry hits.

How long does one A2S pod last?

Depends on how much you vape and what you fill it with. Many vapers get a week or so per pod. Dark or heavily sweetened liquids gunk the coil faster, so those drop off sooner.

Does the A2S pod leak?

The sealed side port is designed to resist it, and plenty of users report far less seepage than the top-fill pods. Just avoid overfilling and reseat the stopper properly.
