This UWELL Caliburn A2/A2S review looks at the 0.9ohm and 1.2ohm replacement pods sold as one listing for Caliburn A2 and A2S devices. The aim is to help you choose between them using the specifications on our product page, because the two pods differ in resistance, coil and filling method, and each suits a different draw. We have not run hands-on tests for this article, so it is a specification-based review: it explains what each listed detail means and where the listing is silent.
In short, the 0.9ohm A2 pod is described as the richer, slightly warmer option with a top-fill design, while the 1.2ohm A2S pod is described as the smoother, tighter mouth-to-lung option with a side-fill design and a silicone stopper. Both are 2ml pods with press-fit integrated coils and a magnetic connection, sold in a pack of 4. The sections below compare them, and the pack-and-price details are in the specification block further down.

UWELL Caliburn A2/A2S review: what the pods are
The listing is for replacement pods, not a complete device. They are made for UWELL Caliburn A2 and A2S devices, they come four to a pack, and each pod holds 2ml of e-liquid. The listing names the technology as Pro-FOCS, a UWELL flavour system, and describes it as restoring the original taste profile of the liquid. We cannot verify that claim ourselves, so treat it as the manufacturer’s description.
The two variants share more than they differ. Both use a magnetic pod connection, which holds the pod in place and makes swapping quick, and both use press-fit coil installation with an integrated coil. That means the coil is part of the pod: you do not rebuild or replace the coil on its own, and when the flavour drops or the pod wears out you fit a new pod. The listing confirms that the coils cannot be replaced separately.
Where they differ is resistance and filling. The 0.9ohm pod is the A2 pod, with a UN2 meshed coil and a top-fill design. The 1.2ohm pod is the A2S pod, with a side-fill design that uses a silicone stopper. Knowing which of those two ideas appeals to you is most of the decision.
What pod resistance means and why it matters
Resistance is measured in ohms and describes how much a coil resists the flow of electricity from the battery. In practical terms it changes how quickly the coil heats and how warm the vapour feels, and it is usually linked to the style of draw a pod suits.
In general, a lower resistance such as 0.9ohm lets more current flow, so the coil heats faster and reaches higher temperatures. A higher resistance such as 1.2ohm lets less current flow, so the coil ramps up more gently and the vapour tends to feel cooler and softer. Those are general principles, not measured results for these particular pods.
The listing frames the choice the same way. The 0.9ohm A2 pod is described as giving enhanced flavour intensity and slightly warmer vapour for a richer experience, and the 1.2ohm A2S pod is described as giving smooth, consistent draws with controlled vapour output for a tighter mouth-to-lung style. Neither pod has a published wattage, puff count or battery figure on the listing, so we do not quote any.
The 0.9ohm A2 pod: UN2 meshed coil and top fill
The 0.9ohm pod uses what the listing calls a UN2 meshed coil. A mesh coil is a woven sheet of metal rather than a single wire, and it spreads heat across a wider surface. The usual benefit is more even heating, which is why mesh coils are popular for flavour. Combined with the lower resistance, the listing describes a richer, slightly warmer result.
The filling system is top fill. You open the pod from the top, add liquid and close it again, which many people find quick when they are out and about. The trade-off is that you need to handle the top carefully, because a top that is not seated properly can let air in or cause leaks. Close it firmly and check the fit before you put the pod back in the device.
Who is it for? Going by the listing, it suits someone who enjoys tasting the detail in sweet, fruit or dessert style liquids and does not mind a draw that is a little more open than a very tight one. It is also the pod to try if you want a slightly warmer vapour.
A practical note for both pods: after filling, let the liquid soak into the coil before you use the pod. The listing itself tells you to ensure proper coil priming and to allow the e-liquid to saturate before vaping. A dry coil burns quickly, and that ruins a pod faster than anything else.
The 1.2ohm A2S pod: side fill with a silicone stopper
The 1.2ohm pod is the A2S pod. The listing describes it as optimised for smooth, consistent draws and a tighter mouth-to-lung style, which is the draw many people associate with a traditional cigarette. Higher resistance generally means a cooler, more restrained vapour, so it is the pod to look at if you prefer a gentle experience.
It fills from the side through a silicone stopper. A stopper seals the fill port after you add liquid, and the listing says this gives added leak resistance and flexibility. As with any seal, it only helps if you push it fully home each time, so check it after every refill.
0.9ohm vs 1.2ohm: side-by-side specification table
The table below puts the two variants next to each other using only figures from the product listing, so every row in this UWELL Caliburn A2/A2S review is traceable to the listing. We dropped any detail the listing does not state.
| Pod | Resistance | Coil | Filling | Capacity | Pack |
|---|---|---|---|---|---|
| UWELL Caliburn A2 pod (this review) | 0.9ohm | UN2 meshed coil, integrated, press-fit | Top fill | 2ml | 4 pods |
| UWELL Caliburn A2S pod | 1.2ohm | A2S coil, integrated, press-fit | Side fill, silicone stopper | 2ml | 4 pods |
The pattern is straightforward. The two pods share capacity, connection, coil installation and pack size, and they differ in resistance, coil description, fill method and the feel the listing associates with each. If you are still undecided, buying one pack of each and comparing them in your own device is a sensible way to settle it.
How to choose the right pod for your style
Start with the draw. If you want a tight, cigarette-like mouth-to-lung pull, the 1.2ohm A2S pod is the natural starting point. If you prefer a slightly more open draw with more warmth and flavour intensity, try the 0.9ohm A2 pod. Neither is better in absolute terms; they simply suit different habits.
Then think about refilling. If you like to top up quickly and are careful with caps, the top-fill A2 pod works. If you would rather have a sealed port and are happy to take the pod out to fill it, the side-fill A2S pod works. The listing describes the A2S stopper as adding leak resistance, so it may appeal if leaks have annoyed you before.
If you want a wider look at Uwell pods, our Caliburn A3 2ml pods review and Caliburn G3 series pods review cover neighbouring pod families, and the coil resistance guide explains the numbers in more depth.
Care, priming and getting more from your pods
A few simple habits help any integrated-coil pod last longer. Prime a new pod properly before use, because the listing stresses coil priming and saturation. Keep the liquid level above the minimum mark, because a coil that sits in an empty pod burns the cotton and spoils the flavour. And give the pod a pause between long strings of puffs so the cotton can re-wet.
Replace a pod when the flavour fades, when it tastes burnt, or when it leaks despite being seated correctly. An integrated coil cannot be rescued with more power or a fresh fill. If you want to understand the coil side more deeply, read how to change a vape coil, keeping in mind that these pods have integrated coils that you replace with the whole pod.
UAE rules, age limit and safe use
These pods are for adults aged 21 and over only, and UAE law may set a higher age limit in some circumstances. Check the current rules before you buy, and never pass a device or pods to a minor. Our age verification page explains how we handle it.
The UAE regulates vaping products under the national standard UAE.S 5030:2018 standard (MoIAT), which sets requirements for products and labelling, and products are expected to carry ECAS certification. Look for the mark on the pack, and ask the seller if it is missing. Replacement pods are only one part of the system, so make sure the liquid you use is registered and labelled as well.
The World Health Organization tobacco fact sheet states that tobacco and nicotine products are harmful, and nicotine is addictive. The NHS guidance on using e-cigarettes explains the position in the UK for adults who are trying to stop smoking. Pods and devices are for adults who already use nicotine, not for non-smokers, young people, or anyone who is pregnant or breastfeeding. Nothing here promises a health benefit.
Keep liquid out of reach of children and pets, wipe up spills straight away, and never refill a pod while the device is charging. Keep the label of any liquid you use, since registration details and strength are printed on it.

Pros, cons and our verdict
| Pros | Cons |
|---|---|
| Two resistances in one listing: 0.9ohm and 1.2ohm | Only fits Caliburn A2 and A2S devices |
| Pack of 4 pods, listed at AED 40 | Integrated coils cannot be replaced separately |
| Top-fill and side-fill options | Top-fill cap needs careful handling |
| Magnetic connection and press-fit installation | No wattage, puff or battery figures on the listing |
| 2ml capacity on both pods | Pods wear out and must be replaced |
Our verdict: these pods are a straightforward way to keep a Caliburn A2 or A2S running, and the two resistances give you a real choice between a warmer, richer draw and a smoother, tighter one. Their limits are device-specific fit and integrated coils that you replace with the pod. That is the bottom line of this UWELL Caliburn A2/A2S review: pick the 0.9ohm pod for flavour and warmth, and the 1.2ohm pod for a tighter, quieter draw.
