As an upgrade version of the Double Barrel V2.1, the Squid Industries Double Barrel V3 is a perfect combination of visual and hand feeling. Powered by dual 18650 batteries, the Double Barrel V3 can fire up to the max output of 150W. The Double Barrel V3 features a 0.47 inch flat top OLED display. The most obvious benefit of this flat top structure is that it can avoid condensation liquid entering into the Mod, effectively preventing the device being damaged. To ensure the compact appearance of the device, the V3 adopts one-piece battery cover for convenient operation. Plus the multi-function fire and various protections, the Double Barrel V3 is definitely a safe and simple device.
