This Uwell Caliburn A2s review looks at the ultra-compact Uwell Caliburn A2s 15W pod system sold in Dubai and across the UAE for AED 99, with a 520mAh battery, a 2ml side-fill pod on a 1.2 ohm mesh coil, USB Type-C charging and six colours. Verdict: a simple, pocketable, draw-activated device for adults who want zero settings, but not the pick if you need adjustable power, airflow control or a bigger battery.

What Is the Uwell Caliburn A2s?
The Caliburn A2s is a rechargeable, refillable pod system from Uwell, built around a lightweight aluminium alloy body and a fixed 15W output. There is no wattage setting to change and no button to press: you inhale and it fires. It is sold at Vape Store Web as the Uwell Caliburn A2s 15W Pod System, and Uwell products sit in our Uwell brand hub.
The table below lists the specifications from the live product page.

Charge time and puffs per pod are not specified by the manufacturer listing, so we do not give figures for them.
Put simply, the A2s trades features for simplicity. Everything you can change on a larger kit, such as wattage and airflow, is fixed here, and that is the point of the design. It gives you a small, predictable device with a refillable pod rather than a single-use product, and the two included pods mean you can start straight away.
Uwell Caliburn A2s Review: Design and Build
The Caliburn A2s is slim at 21.3mm wide and 11.7mm thick, and light at 30g, so it slides into a pocket without feeling like a device. The aluminium alloy chassis gives it a sturdier feel than a plastic body, and the pod is made from PCTG.
Two practical touches stand out. A juice viewing window lets you see the e-liquid level at a glance, and the magnetic pod connection makes swapping pods quick and clean.
The 110.1mm length keeps it slimmer than most kits with a bigger battery, which matters if you carry it every day. Because the body is aluminium alloy, it should handle knocks in a bag better than a plastic shell, though the listing makes no durability claims and we do not add any.
The pod fills from the side through a silicone stopper, which keeps the fill port sealed once you are done. The listing states these pods are compatible with both the Caliburn A2 and A2s.
Colour options
The A2s is offered in six colours on the product page.
- Black
- Blue
- Gold
- Gradient
- Grey
- Purple

Battery, Charging and Does It Last?
The A2s has a 520mAh integrated battery and charges over a USB Type-C port. That is a modest capacity, sized for a small MTL-style device rather than an all-day heavy-use kit.
The listing does not give a charge time or a puffs-per-charge number, so we will not invent one. Your real battery life depends on how often you draw and how fast you vape, and the fixed 15W output means the device does not let you trade power for runtime.
In practice, plan to charge it as part of a routine, for example overnight, and keep the Type-C cable you already use for your phone. Nothing on the listing suggests it can be used while charging, so we do not say either way.
Safety features listed on the product page include short-circuit protection, low-voltage protection, an 8-second timeout and an open-circuit prompt. These are protections built into the device, and they do not make vaping risk-free.
If you want a larger battery in a similar footprint, the comparison table below shows a 1000mAh option from the same catalogue.
Who Is the Uwell Caliburn A2s For?
The A2s suits adult smokers and existing vapers who want a device that asks nothing of them. No buttons, no wattage, no airflow ring: you pick it up and inhale. That makes it easy to recommend as a first pod device for an adult who already uses nicotine.
It also suits people who value size. At 30g and around 110mm long, it disappears in a pocket or bag, and the viewing window removes any guesswork about when to refill.
Because the pod is refillable, you choose the e-liquid, and the listing does not name a recommended strength or type. Within the UAE cap of 20 mg/ml, pick a strength that matches your current habit and check the bottle for the ECAS/MoIAT mark.

Not for you if…
Skip the A2s if you want adjustable wattage, because the output is fixed at 15W. Skip it if you want airflow control, larger vapour or a big battery. Skip it if you are under 18 or do not already use nicotine. Nicotine is addictive, and this device is not a way to start or a proven way to quit.
A fixed-output device also means what you see is what you get: if the 15W draw feels wrong for you, there is nothing to tune, and a different kit is the only fix.
How Does the Uwell Caliburn A2s Compare?
In this Uwell Caliburn A2s review, the comparison shows a cheap, simple device that gives up battery size and airflow control to rivals. Figures come from each product page, and each rival links to its own review.
| Device | Price (AED) | Battery | Power | Pod | Where it wins |
|---|---|---|---|---|---|
| Uwell Caliburn A2s (this page) | 99 | 520mAh | 15W fixed | 2ml, 1.2 ohm mesh | Higher wattage than the AK3, 6 colours |
| Uwell Caliburn AK3 | 120 | 520mAh | 13W max | 2ml, 1.0 ohm mesh | Interactive logo light, fast-charge claim |
| Vaporesso Xros Nano | 119 | 1000mAh | Up to 16W | 2ml, 0.8 or 1.2 ohm | Bigger battery, airflow control |
| Myle V5 Pod System | 75 | 380mAh | Not specified | Pre-filled pods, sold separately | Lowest price, LCD puff counter |
The Xros Nano doubles the battery for AED 20 more, and the V5 costs AED 24 less but uses pre-filled pods and has a smaller battery. Against the AK3, the A2s is AED 21 cheaper with the same 520mAh cell.
If your priority is the lowest entry price and you accept a closed, pre-filled pod, the Myle V5 is the budget option. If you want control over airflow and a larger battery, the Xros Nano earns its higher price. The A2s sits in the middle: refillable, simple and inexpensive, with no extras.

How to spot a fake in the UAE
Check the box for the ECAS/MoIAT conformity mark, confirm the A2s ships with two 1.2 ohm A2S pods as listed, and buy from a licensed store. A price far below AED 99 from an unknown seller is a warning sign. If the mark is missing, do not buy.
