- Small Description: Uwell Caliburn GPP pods are refillable cartridges designed for Uwell Caliburn G3 and G4 series vape kits. They feature built-in mesh coils and come in various resistance levels (e.g., 0.4Ω, 0.6Ω, 0.9Ω, 1.2Ω) to support both Mouth-to-Lung (MTL) and Restricted Direct-to-Lung (RDL) vaping styles. These pods are known for their leak-resistant design (often incorporating U² Anti-Leak Technology and ultrasonic welding), convenient top or side-fill options, and utilize Uwell’s PRO-FOCS 4.0 flavour technology for consistent and rich flavour production. Users simply replace the entire pod when the coil wears out, rather than changing individual coils.
