VaporGenie Coil Bat

No, provided it is used correctly. A metal filter sits between the flame and the material: The lighter heats the filter, the filter heats the air, and this air vaporizes the herb. The flame does not reach the material directly.

No. It has no battery, charging port or electronics. All that is required is a lighter — a jet-flame lighter also works, but is not necessary.

What makes the “Coil" model special is its five-part coil: It can be completely unscrewed by hand, allowing each component to be cleaned individually. There is also an air gap between the inner and outer coils, which keeps the exterior cooler.

The temperature is controlled by how long you hold the flame in place and by the speed of your draw; this type of device does not offer an adjustable temperature in degrees. It takes practice and is the key difference compared with an electric vaporizer.

The Coil Bat is cleaned by unscrewing it and cleaning the metal parts with isopropyl alcohol. Because all five coil components can be separated, every surface is accessible — unlike devices with a permanently installed filter.

The exterior becomes considerably less hot than the heating area because the air gap between the inner and outer coils acts as insulation. The device naturally becomes hot directly around the filter.

A flame-powered vaporizer is suitable for anyone who does not want to charge a device and prefers a tool that can be completely dismantled and repaired. Anyone who wants precise, repeatable temperatures would be better served by an electric vaporizer.
