Hellvape AREZ 120W TC Box Mod, featuring the advanced HellChip Chipset, up to 120W output range, can utilize a 18650, 20700, or 21700 battery. Built from a single unit of stainless steel and zinc alloy, the chassis of the AREZ Mod can deliver superior protection against light falls and drops. Accepting a single high amp battery, the AREZ Mod can naturally utilize 20700/21700 batteries but can accommodate a 18650 battery with the included battery adapter. The max wattage output is 120W when used with a 21700 battery, but loses 20W from the wattage ceiling with each battery size down to 80W when used with a 18650 battery. Encapsulated within the unibody chassis is the Hellchip Chipset, crafted by a reputable chipmaker that is incredibly responsive and can switch between 5 user interface colors.
