UWELL Caliburn AK3 Pod Mod
A portable MTL pod device combining a compact KOKO design, draw-activation, a logo-shaped LED indicator, and a top-fill Caliburn A3 pod cartridge system.
UWELL Caliburn AK3 is an easily portable pod system with slightly curved edges and a compact KOKO form factor. Thanks to the silicone lanyard included in the package, the device can be transformed into a wearable neck accessory.
The 520mAh built-in battery, maximum 13W constant output, and 1.0Ω mesh pod structure are primarily tailored for tight MTL vaping. There is no firing button on the device; it operates automatically when the user takes a draw via the airflow sensor.

Key technical features of the UWELL Caliburn AK3
Compact and Portable KOKO Design
The slightly curved side profile helps the device fit comfortably in the hand. The aluminum alloy body weighs only approximately 35.8 grams.
The silicone lanyard included in the package allows the device to be carried without placing it in a pocket or bag. Even without the lanyard, its compact dimensions make it ideal for daily carry.
Logo-Shaped LED Indicator
The LED shaped like the Caliburn logo on the body creates light animations during draws and indicates battery status in different colors. The LED also notifies the user in case of low voltage, short circuit, and over-puff warnings.
If desired, the light animation can be turned on or off by removing and re-inserting the pod three times within approximately 1.5 seconds.
