The BISON Airlighter 520 is a cordless fire lighter that will light any type of charcoal, wood, or wood pellets in 60 S. It uses a patented torch flame & blower technology to ignite wood or coals quickly & then it spreads the heat to the rest of the fire with the built-in blower. It is powered using a USB rechargeable battery & Butane fuel. For best performance, we recommend using Bison's Airlighter fuel, which is chef-grade, meaning it burns very clean & can be used directly on food to sear meats, caramelize sugars, etc. Lighting charcoal grills: to use the Airlighter simply aim the flame at the coals from a distance of about 3". After you have about 2" Of glow (10-20 S) switch to blower mode. The blower will then spread the fire quickly. Lighting fireplaces or Wood-stoves: we suggest to begin by warming the flu first by aiming the flame up the chimney for 20 S to start the draw of air. Then, simply aim the flame directly to your wood until it is lit. Switch to blower mode to spread the fire quickly. Boost your fire: if you are grilling or lighting a wood Fire, you can boost the flames & increase the heat by simply using the blower. No need for lighter fluid or starters: the Airlighter is strong enough to light your fire quickly without needing any chemical assistance. Your food will taste better & its much safer alternative to lighter fluid.
