In colder climates, the gas pressure decreases. Butane is a liquid at cold temperatures and needs to be warmed up to become a gas. Allow the lighter to rest at domestic room temperature for 10 minutes (ideally reaching temperature of 72F or 20C). If outdoors, warm the lighter for 15-20 seconds by holding it in palm of your hand or simply keep the lighter in the inside pocket of your coat! You can also increase the flame height a fraction - say 1/4 turn until desired flame height is reached. Note that we even have had customers using Turboflame in North Pole expeditions! (but this particular gentleman ran a sting through the lanyard hole and hung it around his neck!). We even have heard of skiers keeping them in their glove to keep warm - for an instant flame when they reach the bottom of the slope.
