Freemax Maxus Pro Sub-Ohm Tank better known as the M Pro 2 Tank is a highly innovative atomizer featuring a large 5mL juice capacity, sliding top fill system, dual slotted airflow, and utilizes the Freemax Maxus Pro Coil Series. Its the upgraded version of the FreeMax Mesh Pro Tank. The M Pro 2 Tank offers a large bulb glass tube able to fit 5mLs of your preferred e-liquid. Freemax integrated a fill port at the top of the tank that is quickly accessed by a slide-to-open top fill cap making it more leak-resistant than its competitors. A dual slotted adjustable airflow system is added located at the bottom portion. The airflow system provides plenty of air for cloud vaping but can be restricted to create that tight draw many vapers seek. The Freemax Maxus Pro Sub-Ohm Tank uses the high-performing Freemax M Mesh Coil series including the all-new FM CoilTech 4.0 coils delivering superb cloud and vapor production on every puff. The new Freemax Maxus Pro 904L M Coil Series integrates SS904L Mesh with Tea Fiber cotton and varying wattage ranges from the four options: M1, M2, M3, and M4.
