The invention discloses a portable wireless charging film with a protective circuit. The portable wireless charging film with the protective circuit comprises a receiving end circuit, a plastic film, a connecting circuit and a charging connector, wherein the receiving end circuit is fixedly arranged above the plastic film; a flat protective shell is arranged outside the receiving end circuit; the receiving end circuit and the charging connector are connected through the connecting circuit; the receiving end circuit comprises an induction coil L3, a bridge rectifier circuit D4, a capacitor C6, a capacitor C5, an LM317 integrated chip, a capacitor C7, a diode D3, a diode D5, a resistor R8, a sliding rheostat R9, a capacitor C8, a resistor R10, a power supply BT1, a triode Q4, a voltage stabilizing diode D7 and a diode D6. By virtue of a simple structure and an integrated circuit, the portable wireless charging film with the protective circuit endows an ordinary equipment battery with a wireless charging function, so that wireless charging of ordinary equipment can also be achieved, and disorder caused when the ordinary equipment is charged is avoided.
