There are two options available to cater to various vaping preferences: the 0.7Ω and 1.2Ω options. The 0.7ohm pod is designed to deliver enhanced vapor production, while the 1.2ohm version ensures a longer vaping experience by optimizing battery efficiency. In terms of refilling, the e-juice can be easily replenished by removing the silicone cap located on the side of the device.
