A traditional lighter is a portable device used to generate a flame. It consists of a metal or plastic container filled with a flammable fluid or pressurized liquid gas, a means of ignition, and some provision for extinguishing the flame.

Jet lighters or torch lighters have strong flame ( some with double, triple even quadruple flames). They generate much high temperature as well.

USB chargeable lighters are modern lighters. They don't need any gas or liquid. Just use rechargeable embedded battery to generate an electric arc.
