Why Choose the Uwell Caliburn A2S?
Simple Draw-Activated Vaping
The Caliburn A2S activates when you inhale, so there is no fire button to press and no wattage setting to adjust. This makes the device easy to use for new vapers and convenient for experienced users who prefer a simple pod kit.
Take a steady mouth-to-lung inhale through the mouthpiece and the device will activate automatically. If the device does not fire, check that the pod is fitted correctly and that the battery has sufficient charge.
520mAh Built-In Battery
The A2S uses a 520mAh internal battery to power the device. Its compact size makes it suitable for carrying throughout the day, while the built-in design means you do not need to purchase or install separate batteries.
Battery life depends on your vaping frequency, puff length and coil resistance. The LED indicator provides a quick visual guide to the remaining battery level.
2ml Refillable Side-Fill Pod
The included Caliburn A2S pod holds up to 2ml of e-liquid and is refilled through a side-fill port. The pod has a transparent design, allowing you to check the e-liquid level without removing it from the device.
Refilling before the e-liquid level becomes too low helps keep the integrated mesh coil saturated and can reduce the chance of dry hits.
1.2Ω Mesh Coil for MTL Vaping
The included pod contains a 1.2Ω FeCrAl UN2 meshed coil. This resistance is designed for a tighter mouth-to-lung draw with controlled vapour production and a cooler vaping experience than lower-resistance pod coils.
Because the coil is built into the pod, you replace the complete pod when the coil reaches the end of its usable life. There is no separate coil to remove or install.
Compatible with the Caliburn A2 Pod
The Caliburn A2S is also compatible with the 0.9Ω refillable Caliburn A2 pod. This gives you another option if you prefer a slightly warmer draw or increased vapour compared with the included 1.2Ω A2S pod.
Check the pod packaging before purchase to confirm compatibility and resistance. The A2S pod and the A2 pod use different fill designs, so always follow the instructions supplied with the specific replacement pod.
Pro-FOCS Flavour Technology
Uwell's Pro-FOCS flavour technology is designed to help deliver a clear and consistent flavour from your e-liquid. The meshed coil heats the e-liquid evenly to support a satisfying MTL experience.
For the best flavour, prime a new pod before use, choose a suitable 50/50 e-liquid and avoid vaping when the pod is nearly empty.
USB Type-C Fast Charging
The Uwell Caliburn A2S uses USB Type-C charging for convenient recharging. Uwell states that the battery can reach approximately 90% capacity in around 30 minutes under the specified charging conditions.
Use a suitable charging cable and power source, and disconnect the device when it has finished charging. Do not charge the device if the charging port, cable or battery shows signs of damage.
LED Battery Indicator
The Caliburn logo illuminates during use and displays different colours to indicate the battery level. This gives you a quick indication of when the device needs to be recharged.
The indicator can also make the device easier to monitor during everyday use without requiring a display or separate control menu.

How to Set Up the Uwell Caliburn A2S
How Do You Fill the A2S Pod?
To fill the A2S pod, remove it from the device, open the side-fill port and add e-liquid through the filling hole. Close the port securely before replacing the pod.
- Remove the pod from the battery device.
- Locate the side-fill port on the pod.
- Open the silicone filling plug.
- Add suitable e-liquid without exceeding the 2ml capacity.
- Close the filling plug firmly.
- Allow the new pod to stand for at least five minutes.
- Insert the pod into the device.
- Take a gentle inhale through the mouthpiece.
How Long Should You Wait Before Vaping?
Wait at least five minutes after filling a new pod so the e-liquid can soak into the integrated mesh coil. Taking puffs too soon can cause a dry or burnt taste.
How Do You Activate the Caliburn A2S?
The Caliburn A2S is activated by inhaling through the mouthpiece. There is no fire button to press. Use a slow and steady mouth-to-lung inhale for the best result.
How Do You Check the E-Liquid Level?
The A2S pod is transparent, so you can view the e-liquid level while it is installed in the device. Refill the pod when the level becomes low and avoid using the device with an almost empty pod.
Which E-Liquid Should You Use with the Caliburn A2S?
The Caliburn A2S is designed for mouth-to-lung vaping and is generally suited to 50/50 e-liquids. Nicotine salts can provide a smooth option for adult vapers who prefer a higher nicotine strength, while standard 50/50 e-liquid can also be used with the correct strength.
The included 1.2Ω pod is designed for a tighter draw and lower vapour production. Choose a nicotine strength that suits your experience and vaping frequency.
Avoid using very thick high-VG e-liquid in the A2S pod, as it may not wick efficiently through the small integrated coil. If the e-liquid is too thick, the pod may produce a dry taste or struggle to keep up with frequent puffs.
Nicotine-containing e-liquid is intended for adults aged 18 and over. Nicotine is addictive. Follow the product label and use nicotine strengths responsibly.
How to Get Better Performance from the Caliburn A2S
- Prime every new pod before vaping.
- Wait at least five minutes after filling a new pod.
- Use a suitable 50/50 e-liquid.
- Take slow, steady mouth-to-lung puffs.
- Keep the pod filled above the minimum e-liquid level.
- Do not allow the pod to run completely dry.
- Clean condensation from the pod connection regularly.
- Keep the airflow path clear.
- Recharge the battery before it becomes completely empty.
- Replace the pod when the flavour becomes burnt or muted.
- Keep the device away from excessive heat and moisture.
- Do not use a damaged pod, cable or charging port.
When Should You Replace the A2S Pod?
Replace the A2S pod when you notice a persistent burnt taste, weaker flavour, reduced vapour production or a harsh inhale. The pod contains an integrated mesh coil, so the complete pod must be replaced rather than only the coil.
Pod lifespan depends on e-liquid sweetness, vaping frequency, puff length and how often the pod is allowed to run low. Keeping the pod topped up and allowing the coil to remain saturated can help it last longer.
