The Air Pro Kit, by Suorin, is a tiny business card-sized e-cig that features a compact cartridge that holds 4.9 ml of E-Liquid, a mesh coil for outstanding flavor reproduction, and a built-in 930mah battery. The Air Pro uses a new airflow system that increases vapor while reducing heat. This kit is ridiculously easy to use, simply take a drag to activate or use the side fire button for a lighter puff. Simply charge and vape, a perfect starter kit for those who don't want a complicated device. This easily fits in a shirt pocket and can last throughout the day under normal use. An LED displays the remaining battery life and the cartridges can be easily refilled in seconds. Each kit includes a micro-USB cable for charging. These are ruggedly designed and have a zinc alloy body. The Suorin Air Pro kits are available in Black, Navy Blue, Red, Rose Gold, Gunmetal, Gold, or Silver.
