The battery has variable voltage so you can pick the appropriate heat level for the material you are loading. Three small lights above the button indicate whether you are one the Low setting (3.0V), Medium (3.5V), or High (4.2V). This pen comes with a triple quartz coil and a dual quartz coil, in case you prefer a little less heat. Reloading is a breeze with the magnetic mouthpiece, and it even has a 2mL container built-in to the base. Includes product tool and lanyard.
