Uwell Caliburn G4 Classic Pod Vape Kit

What Is the Uwell Caliburn G4 Pod Vape Kit?

The Uwell Caliburn G4 Classic Pod Vape Kit is a versatile pod kit built around a 1400mAh battery, with output up to 35W max. Unlike many pod kits locked into a single vaping style, the Caliburn G4 is designed for both MTL and RDL vaping, giving you the choice between a tighter, cigarette-style draw and a looser, airier one.

It comes with dual mesh coils (0.4Ω and 0.9Ω FeCrAl) included in the box, so you can switch resistances without buying extra straight away. Reversible airflow with a slider control lets you fine-tune your draw further, and twin smart vaping sensors support both inhale and button activation. The 2mL Caliburn GPP pod uses a top-fill system, making refills with your own e-liquid straightforward. If you'd rather avoid refilling altogether, a prefilled kit will suit you better.

Quick answer: The Uwell Caliburn G4 Classic Pod Vape Kit has a 1400mAh battery, 35W max output, supports both MTL and RDL vaping, and comes with dual mesh coils (0.4Ω and 0.9Ω). It charges via USB-C and costs £22.95.

Best Choice For

This kit suits vapers who want the flexibility to switch between MTL and RDL styles without owning two devices, thanks to the reversible airflow and dual mesh coils included. It's also a good fit for anyone who wants both inhale and button activation options. If you'd rather skip refilling entirely, a prefilled kit will suit you better.

Key Features

1400mAh Battery
