Have you ever imagined a special vape device combining the advantages of both pod devices and box mods? Now the RPM40 appears as you required! It is small in size but has a battery capacity of 1500mAh and a power range of 1W-40W for you to adjust. The internal IQ-R chip is a new one, shortening the firing time to 0.001S, and charging time to two hours. The RPM has coils for both Salt Nic's as well as the standard Max VG E Liquids.
