The invention relates to a new-energy lighter. An electronic oscillation circuit, a boosting type DC / DC (direct current) conversion circuit, a lighting circuit and a money detecting circuit are arranged in a casing of the lighter. A switch is arranged on one side of the casing, a lamp and a money detecting lamp are arranged at the bottom of the casing. The direct current carried by the lighter can be used as lighting energy source, high-frequency pulse current can be generated through the oscillation circuit, high-frequency voltage is generated at two ends of a transformer coil, high-voltage discharge sparks can be generated by outputting in an arc discharge manner via a pair of high-voltage discharge needles and can be used for lighting combustible matter in any weather. A power source socket of the lighter is assorted with a universal plug and an adapter, so that the lighter can be used for charging cellphones or digital products in various specifications. Meanwhile, the lighter can be used for lighting and detecting money, and is safe, environment-friendly, energy-saving in use, small in size, convenient to carry, practical and convenient.
