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. Besides, the newly designed RPM Mesh 0.4Ω Coil is designed for the best flavour and excellent vapour production.
