The invention discloses an energy-saving mobile power supply based on
solar energy. The energy-saving mobile power supply comprises a charging interface circuit, a main controller, a power supply
battery pack and an output interface circuit, and also comprises a
solar energy conversion circuit and a
voltage stabilizing circuit. The
voltage stabilizing circuit comprises first and second resistors, first to third capacitors, and a
voltage stabilizer. An input end of the voltage stabilizing circuit is respectively connected to one end of the first
capacitor and one end of the first
resistor. The other end of the first
capacitor is grounded, and the other end of the first
resistor is connected to an input end of the voltage stabilizer and one end of the second
capacitor. A ground end of the voltage stabilizer is connected to the second
resistor and then grounded, and the other end of the second capacitor is grounded. An output end of the voltage stabilizer is connected to the third capacitor to act as an output end of the voltage stabilizing circuit. According to the invention, the energy-saving mobile power supply based on the
solar energy can realize the energy collection and conversion, is conducive to sustaining the energy of the power supply
battery pack and prolonging the service life of the
battery pack, and further improves the charging and voltage stabilizing effects.
