Uwell Caliburn A3 Refillable Pods

The Uwell Caliburn A3 replacement pods are the dedicated refillable pods for the Caliburn A3, AK3, and AZ3 pod kit range. Each pod holds 2ml of e-liquid and comes with a pre-installed 1.0ohm FeCrAl meshed coil, making them a straightforward drop-in replacement without any coil-swapping required. 

The top-fill system, accessed by lifting the mouthpiece, makes refilling quick and tidy. Clear PCTG construction means you can check your e-liquid level at a glance, and the magnetic base locks securely into the device. Sold in a pack of 4, these pods are a reliable choice for any mouth-to-lung vaper using a Caliburn A3 series kit.

2ml E-Liquid Capacity

Each Caliburn A3 pod holds a full 2ml of e-liquid, in line with UK TPD regulations. That capacity is comfortable for a day of moderate vaping before a refill is needed. The pod is made from transparent PCTG, so the e-liquid level is visible without removing the pod from the device. Keeping an eye on the level means you can top up before the coil runs dry, which helps avoid any burnt taste.

1.0ohm FeCrAl Meshed Built-In Coil

The pod comes with a 1.0ohm FeCrAl meshed coil already installed, so there is nothing to set up before use. Mesh coil construction spreads heat evenly across the wicking material, which improves flavour consistency and reduces the chance of hot spots. The 1.0ohm resistance is suited to mouth-to-lung vaping and pairs well with 50/50 e-liquids and nicotine salts. Because the coil is integrated into the pod, you simply replace the whole pod when the coil reaches the end of its life.

Top-Fill System via Removable Mouthpiece

Refilling the Caliburn A3 pod is a one-handed job. The mouthpiece lifts off to reveal the filling port underneath, and once you have added your e-liquid, the mouthpiece presses back into place. This top-fill design keeps the filling port away from the device's air channels, which reduces the chance of spillage reaching the battery section. It is worth giving the pod a few minutes to sit after filling so the coil can absorb the liquid before you start vaping.

Magnetic Pod Connection

The base of each pod features a magnetic connection point that clicks firmly into the Caliburn A3, AK3, or AZ3 device. This means the pod is easy to insert and remove from either side without fumbling, and sits securely during use. The magnet holds the pod in place firmly enough to prevent accidental disconnection in a pocket or bag. When you are ready to swap in a fresh pod, the change takes only a second.

PCTG Construction with E-Liquid Viewing Window

Uwell uses PCTG (polycyclohexylenedimethylene terephthalate glycol) for the pod body, a material chosen for its durability and clarity. The transparent shell acts as a large e-liquid viewing window, giving you a clear, unobstructed view of what is left in the pod. There is no need to remove the pod from the kit to check the level. PCTG is also resistant to the chemicals found in e-liquid, which helps maintain the pod's clarity over its lifespan.

Pro-FOCS Flavour Adjustment Technology

Uwell's Pro-FOCS (Flavour Optimisation Coil System) technology is built into the Caliburn A3 pod design to improve flavour accuracy. The system is engineered to make better use of every drop of e-liquid that passes through the coil, reducing waste and maintaining consistent flavour output. Compared to earlier Caliburn pods, the A3 generation delivers a noticeably cleaner taste, particularly with fruit and menthol nicotine salts. This is one of the main reasons the Caliburn A3 range continues to be a well-regarded choice for flavour-focused vapers.

Mouth-to-Lung (MTL) Vaping

The Caliburn A3 pods are designed specifically for a mouth-to-lung draw, which closely mirrors the sensation of smoking a traditional cigarette. The airflow and coil resistance work together to produce a tight, controlled draw with a satisfying throat feel, making these pods a natural fit for people switching from cigarettes. Nicotine salts in the 10mg to 20mg range pair particularly well with MTL setups, delivering a smooth hit without harshness. If you are new to pod vaping, this style of device is one of the most straightforward starting points available.

Compatible with Caliburn A3, AK3, and AZ3 Kits

These pods are cross-compatible across the Uwell Caliburn A3 series: the original Caliburn A3, the Caliburn AK3, and the Caliburn AZ3. All three devices use the same pod design and magnetic connection, so a single pack of replacement pods will work across any of these kits. It is worth noting that these pods are not compatible with the older Caliburn A2 or AK2 models. If you use an A3S kit, Uwell also produce a side-fill A3S pod that works alongside these top-fill versions.

Sold in a Pack of 4

Each pack contains four Caliburn A3 replacement pods. Having a pack of four to hand means you always have a fresh pod ready to go when one reaches the end of its coil life. Pod lifespan varies depending on the e-liquids you use and how frequently you vape, but most users find a single pod lasts one to three weeks with regular use. Sweeter e-liquids and high-VG blends tend to shorten coil life, while 50/50 blends and nicotine salts are generally easier on the coil.
