How Do Variable-Voltage Electronic Cigarettes Work?
Variable-voltage electronic cigarettes use 3.7-volt batteries, just like standard electronic cigarettes. The difference is in the fact that a variable-voltage e-cigarette includes a booster circuit that stores and regulates power from the battery, delivering it to the atomizer or cartomizer at the voltage you select.
Many variable-voltage e-cigarettes also include microprocessors for safety and precise control over vapor production. These advanced internal electronics often make variable-voltage e-cigarettes more expensive than standard e-cigarettes.
