Abstract:
1. A universal power converter comprising: a body; the body having a front surface, a back surface, a top surface, a bottom surface and two lateral surfaces; the front surface having a first connecting wire and the bottom surface having a second connecting wire; a circuit module contained in the casing; one end of the first connecting wire and one end of the second connecting wire being connected to the circuit module; another end of the first connecting wire being connected to an input of a power supply; another end of the second connecting wire being connected to an external device; a voltage adjusting button, a data display screen, and an actuating switch which are wired-connected to the circuit module being installed on the top surface; wherein the circuit module includes a power converter circuit; the power converter circuit being a power supply and charging circuit; and a voltage adjusting circuit; the voltage adjusting circuit including a main controller; the main controller being installed with a plurality of output ports; each output port being serially connected to a respective transistor and a specific resistor value; each resistor value representing a specific output voltage which is feedback to the power converter circuit; the main controller serving for automatically opening or closing a selected voltage and for driving the signals from the data display screen and the actuating switch.
