Have you ever imagined a vape device combining the advantages of both pod devices and box mods. The RPM40 fits the bill. It is small in size but has an internal battery capacity of 1500MaH, with a power range of 1W-40W. The internal IQ-R chip is a new one, shortening the firing tome to 0.001S. Protection features include high-temperature protection, short circuit protection, low voltage protection, and 8-second cut-off.
