The iStick Power Nano is a great kit available from eLeaf that includes an iStick Power Nano mod and MELO 3 Nano atomizer. The tank can be easily filled by removing the top cap, and two coils are included with the kit. This kit can be easily pocketed or carried in your purse, and despite its compact size, it's very satisfying to use! The mod can be adjusted up to 40w, and features an internal battery with USB charging so you can charge it in your car or at home with a standard Micro USB cable (included). The tank also features adjustable airflow so you can control the vaping experience and customize it to your preferences.
