The Vaporesso XROS 4 Nano is compatible with all XROS series pods, including resistances from 0.4Ω up to 1.2Ω, making it ideal for both freebase and nicotine salt e-liquids. This technology enhances flavour by providing a more efficient, even heat distribution across the coil, producing consistent, smooth vapour with each puff and helping to extend coil life.
