Plasma lighters are electronic lighters that contain no butane. Usually, you can charge them using a USB cable, though some come with specific charging kits.
They feature a pair of ceramic electrodes. When you click the lighter, it creates a small plasma arc that runs between the two electrodes. This arc is hotter than a regular flame and comes with none of the smell attached to fire. As a result, many point to plasma lighters as the best way to light cigars.
They also have a variety of names. These include Tesla lighter, arc lighter, and flameless lighter
