UWELL
The Uwell Caliburn G4 Pod Kit is the latest fourth-generation release in the iconic Caliburn series, designed for vapers who want a premium balance of flavour, style, and convenience. Carrying forward Uwell’s tradition of innovation, this upgraded pod system introduces new PRO-FOCS flavour technology for a richer, more consistent taste experience while extending coil life by up to 35%. Whether you’re chasing a smooth MTL (mouth-to-lung) draw or prefer an airier RDL (restricted direct-lung) vape, the G4 delivers both with precision.
Powered by a 1300mAh built-in battery with USB-C fast charging, the Caliburn G4 ensures reliable performance all day. Its intelligent chipset offers two unique vaping modes—Storm Mode for intense flavour and cloud production, and Waves Mode for a smoother, relaxed experience. Paired with Uwell’s latest GPP pod series, this kit provides seamless pod compatibility, leak-resistant design, and an ergonomic, lightweight aluminium body perfect for on-the-go vaping.
The Uwell Caliburn G4 Pro upgrade introduces further usability improvements, including enhanced airflow adjustments, leak protection with the U² design, and a stylish aesthetic available in multiple striking finishes. Ideal for both beginners and experienced users, this pod kit is a versatile all-rounder in the world of portable vaping.
Among its modern innovations and practical conveniences, the Caliburn G4 keeps things simple yet delivers powerful performance. Backed by Uwell’s intelligent chipset and the latest PRO-FOCS 4.0 flavour-enhancing technology, the G4 ensures every puff is smooth, consistent, and satisfying.

The wide 0.85-inch TFT colour screen makes it easy to check battery life, wattage, and puff count at a glance. Switching between Storm Mode for maximum clouds and Waves Mode for a smoother vape is seamless, giving you full control over your experience with minimal effort.

The Caliburn G4’s adjustable airflow slider allows you to customise every draw. Choose a tighter, flavour-rich MTL inhale or a looser RDL vape with enhanced vapour production. Combine this with pod orientation adjustments, and you get a tailored airflow system that adapts perfectly to your preference.

Engineered for flexibility, the G4 is compatible with both Uwell’s GPP and G3 pod series. This opens up a wide choice of resistances, from smooth nic salt MTL vaping to airy freebase RDL sessions. The leak-resistant pod design ensures clean refilling and consistent flavour delivery.

With Uwell’s U² ultrasonic leak-resistant welding and precision pod design, the G4 minimises leaks while maximising airflow efficiency. Combined with PRO-FOCS flavour technology, this ensures your e-liquid delivers a pure, satisfying taste from the very first puff to the last.
