The Suorin Air is a fantastic discrete vape device. A card-style ultra portable pod system, the Air features Suorin's Refillable Cartridge/Pod System that allows you to utilize your favorite E-Liquids. An "all in one" system with flow switch firing, 2ml pods, and a 1.2 ohm atomizer in the cartridge. A 400 mAh built in battery powers the device and the Air has a battery life indicator as well . Simple, convenient, and not much bigger than a credit card, the Air is a great choice for clandestine use and convenient portability.
