The RPM2 utilizes a three-button layout to manipulate the controls. A single fire button is used for firing the device and allows users to select different options. Located below the 0.96" OLED Display, two buttons allow users to change the wattage from 1 to 80W, clear puff counter and change the background colours. The OLED screen gives the user an easy readout of power settings, battery life, puff counter, seconds counter, voltage output, and ohm level. Draining the battery on the device will prove to be a difficult matter since the battery capacity has been upgraded to a 2000 mAh integrated battery and has a firing rate of 0.001 seconds. Another handy feature is the utilization of USB-C for charging and updates to the IQ-R Chip.
