Uwell Caliburn G3 Replacement Pods come with integrated coils: 0.6Ω, 0.9Ω, or 1.2Ω in 2.5mL, plus the 0.4Ω 3mL pod introduced with the G3 Pro. The coil is built into the pod, so a pod swap is also a fresh coil. Compatible with: the Caliburn G3 (currently out of stock) and the G3 Pro line. Not for the Caliburn G, G2, A, or X series: the G uses G pods, the G2 uses G2 pods (currently out of stock), the A series uses its own pods (A2, A3), and the X uses X pods.
