Rofvape Witcher kit is an all-in-one vape setup that includes both a Witcher Tank and a 75W box mod with temperature control and a submerged tank setup. Submerged tank was the first to use the "Roman column" airway design and solve the problem that atomizer air flow only from the surface of the coil cause poor taste. 

The kit measures 25mm x 98mm x 64.5mm and is made from zinc alloy (mod) and stainless steel/glass (tank). The mod is built with a submerged atomizer system which makes the kit compact, portable and safer to transport. The device looks very modern and its form factor was designed to be easily held in the palm of the hand. It is available in silver, black, blue and red.

The Witcher mod utilizes a single 18650 battery that is loaded from the bottom via a threaded battery cap. The mod also has a USB port for easy charging of the cell. The mod have super high efficiency up to 98% which is very high for a regulated device. The power output range is 7W to 75W and there’s also temperature control operation that works with all coil types such as nickel, titanium and stainless steel. The temperature range is 200 to 600 degrees Fahernheit and the lowest atomizer resistance is 0.2Ω.

The tank features top adjustable airflow and coil access at the bottom, resulting in separated airflow and e-liquid flow for mess-free coil swapping and preventing spitback. The tank has a 5.5ml capacity and features a top fill system for conveniently adding e-juice. The tank comes with a 0.5Ω kanthal coil that can handle up to 100 watts of power with great flavorful clouds that are said to never taste burnt. 

Rofvape Witcher Box Mod has finished the TPD Emmision Test, don't worry.
