Abstract: FIELD: power supply. 
     SUBSTANCE: group of inventions relates to four options of a power supply unit for an aerosol inhaler. In the first embodiment, the power supply unit for the aerosol inhaler contains a power source designed to supply energy to the element, designed to form an aerosol by spraying the aerosol source. The power supply unit includes a charger designed to control the charging of the power source. The power supply unit has an energy receiving coil, made with the possibility of wireless energy reception. The power supply unit contains a converter made with the possibility to convert AC energy into DC energy. The power supply unit includes a current-carrying AC wire connecting the energy receiving coil and the converter. The power supply unit contains a current-carrying DC wire connecting the converter and the charger and having a length equal to or greater than the length of the current-carrying AC wire. The power supply unit contains a case accommodating the power source, the energy receiving coil, the charger, and the converter. The energy receiving coil, converter, and charger are located above the power source in a vertical direction when the power source is being charged. In the second embodiment, the charger is located above the power source in the vertical direction when the power source is being charged, the energy receiving coil and the converter are located under the power source in the vertical direction when the power source is being charged. In the third embodiment, the power supply unit has a circuit element made in the case. The power supply unit includes a shield made in a case with the possibility of protecting the circuit element from the magnetic field or shielding or attenuating the magnetic field of the scattering of the energy receiving coil. The energy receiving coil is designed for wireless energy reception when the case is placed vertically. The case accommodates the energy receiving coil, shield, converter, and power source in order from the bottom in the vertical direction when the power supply is being charged. In the fourth embodiment, the power supply unit contains a circuit element made in the case. The power supply unit includes a shield made in the case with the possibility of protecting the circuit element from the magnetic field or shielding or attenuating the magnetic field of the scattering of the energy receiving coil. The energy receiving coil is designed for wireless energy reception when the case is placed horizontally. The shield is designed to protect the circuit element from the magnetic field or shielding or attenuating the magnetic field of the scattering of the energy receiving coil in a state, in which the case is located horizontally so that the efficiency of energy reception by the energy receiving coil is maximized, and when the case is rotated in the rolling direction from this state.  
     EFFECT: technical result is the creation of a power supply unit for an aerosol inhaler that can prevent releasing heat caused by the surface effect in the current-carrying AC wire.
