Starter Kit Description The Revenger X 220W TC Starter Kit is the newest flagship model from Vaporesso, a brand that exudes quality of construction and performance in all of their products. Utilizing the NRG Sub-Ohm Tank, and the Omni Board 2.2 chip, the Revenger X is both feature-rich and precise. New to the Revenger X from the previous model is a buttonless haptic feedback touch interface (firing still operated by the button located on side of the device) and an improved startup speed. The Revenger X utilizes two high-amp 18650 batteries which are inserted by removing the magnetic backdoor on the device, and unlike many other devices, it is safe to charge your batteries inside of via USB cable, thanks to its 2.5 amp balanced quick charging capability. Another feature that the Revenger X includes is a “smart variable wattage” feature which allows the device to automatically detect an estimated optimal wattage whenever a new tank, RDA, or RTA is attached.
