A jet flame lighter mixes the gas in the burner itself and blows it out under pressure. That gives you a blue, focused flame that is much hotter than an ordinary yellow flame and that does not blow out.
Jet flame, jetflame and turbo all mean the same thing. The difference is in the number of jets, the finish and whether you refill it.
An ordinary flame needs still air and burns incompletely, which is why it is yellow and sooty. A jet flame takes its oxygen in on the inside. That makes the flame blue, clean and hot enough to get thicker material going as well.
This category holds jet flame lighters with one to four jets, from pocket size to table model, singly and in value sets. Nearly all of them refillable with butane gas.
The blue flame wins wherever there is a draught: at the barbecue, the fire pit, on the campsite and in a draughty hallway. If it mainly needs to cope with wind, have a look at the storm lighters. If you only want models you refill, those are with the refillable lighters.
When comparing, look at the number of jets, whether the flame is adjustable, the tank size and whether it has a lock. Which models hold up best outdoors is in the best storm lighters.
If you are unsure about the number of jets, look at what you light most often. For a candle or a cigar one jet is enough and more economical, and for coals or kindling four jets are noticeably faster.
