The faster, cleaner and safer way to light fires, both indoors and out The revolutionary Bison Airlighter is a portable air-driven fire starter. The new V2 version delivers even further performance improvements. The Airlighter jets a 4-inch flame to quickly ignite charcoal or wood and then delivers an optimized airflow to spread the flames. It is the faster, cleaner, and safer way to light BBQs, campfires, smokers, fireplaces and just about any fire. Being cordless, it is ideal for around the house, camping, picnics, and tailgating. Enjoy cleaner tasting food without the lighter fluid taste, all while helping to reduce lighter fluid usage, which contributes to ozone erosion. How it works Ignite your wood or coals by touching them directly with the flame for about 20 seconds. Then activate the air-flow and point it at the ignited spot to spread the flames until you have a strong fire. The amount of time you use the flame or fan is up to you. Times for wood will vary depending on its thickness and moisture levels. Getting started 1) Charge the Airlighter from any USB port (i.e. computer, car, wall adapter). The LED indicator turns green when the battery is full. 2) Fill the tank with butane. We recommend Airlighter Fuel or other high quality non-clogging butane from your supermarket.
