The Nova mod has a 510 connector at the top, the fire button, LCD display and adjustment buttons on the main side and the battery cap on the base. The device is powered by an external 18650 battery (included in the kit) and it’s recommended that you insert the battery and plug in your charger for at least two hours before using it for the first time. The menu is pretty intuitive and you can adjust the wattage between 7  50W in 1W increments by pressing on the plus or minus buttons. The display shows all the information required for an excellent experience, such as remaining battery, atomizer resistance, output voltage and current wattage.
