The Vandy Vape SWELL 188W Box Mod deploys a highly-durable lightweight vape device made in collaboration with Tony B., integrating an advanced Chipset with multi-functional App control and dynamic power adjustments for a dual 18650 platform (batteries sold separately). Constructed from lightweight zinc-alloy, the chassis of the SWELL box mod is impact resistant to light and moderate drops and falls. In addition, the exterior construction is well-engineered, presenting a waterproofed PCBA to prevent short circuits or water from damaging the vaping systems. Equipped with the nifty retrieval function, the SWELL Box Mod can be located if lost, emitting a audible ping with the help of a smart phone loaded with the Vandy Vape App. This innovative feature is what sets Vandy Vape apart from other manufactures, outfitting vaping systems with new features and pioneering technological advances in the vaping industry that improve vaping quality of life.
