Overview

E-cigarettes are composed of main control chips, lithium batteries, buttons, LED breathing lights, atomizers and other components. Through Semiware’s circuit protection product line combination, protection against battery overcharge, over-discharge, heating device short circuit, and anti-drying are added. Burn, short-circuit self-recovery and other functions make it safer and more reliable to use.
