General lighter gas is butane, burning fully, flame strong and stable, no odor.
This is a special butane tank, which is safer to use. There are air holes on the side or bottom of the lighter. Put the bottle of air nozzle against the lighter hole and press it in for a few seconds.
But the lighter can not be inflated with liquefied petroleum gas, because liquefied gas contains propane, propylene, butane, butene. Propane and propylene are too light, the pressure is large, and the weather is slightly hot and the machine will explode - for example, the lighter placed under the windshield of the car is dangerous in the sun, and the body temperature can also increase the pressure of the gas in the machine. If it's possible to fill a lighter with liquefied gas, why make a household liquefied gas tank out of a cylinder instead of plastic? That's the truth.
