Constructed from a smooth aluminium alloy with an abstract laser engraved pattern, altogether the Caliburn A3S makes for a striking, lightweight vape kit – perfect for those who want a pocket friendly device.

The Caliburn A3s has not only a fixed power output, but also a fixed coil in the new A3S pods – with convenient side filling! The PRO-FOCS flavour technology incorporated in the pods undeniably provides a very straight forward vape experience with a consistent flavour each time.

What are the best E-Liquids to use with the Uwell Caliburn A3S Kit?

The OK 50/50 e-liquid range is an excellent match for both MTL and DTL vaping, offering a great balance of flavour, vapour production and throat hit.

You can find out more about PG and VG, and choosing the right vape juices for your kit in our guide to e liquid ingredients.

Will I need replacement coils or pods?

The Uwell Caliburn A3S is compatible with Uwell Caliburn A3s Pods and Uwell Caliburn A3 Pods. This kit will come with two pods to get you started; one 0.8 ohm mesh pod which is pre installed and one 1.0 ohm mesh pod. Please note the A3 pods do not feature the side refilling.

There is no need to replace the coil inside the pod as it is built in, otherwise known as a fixed coil. Once you start getting a deterioration in flavour, it will be time to replace the pod.

Replacement A3S pods can be purchased here.

Upon opening the kit, remove the film from the bottom of the pod. Locate the filler plug on the side of the pod and fill with e-liquid, closing the filler plug securely once full.

Ensure you let the pod sit for 10 minutes to prime the coil and then put the pod into the device. Simply activate the device by inhaling through the mouthpiece to vape. The LED indicator in the Caliburn logo will light up and animate during the draw.
