A universal charging detection device and a universal charging detection method are disclosed herein. The universal charging detection device is provided for a charger that can be electrically connected to an electronic device via a universal serial bus (USB). The universal charging detection device includes a voltage output unit, a current sensing unit, a current level detector and a state machine. The voltage output unit is electrically connected to the electronic device. The current sensing unit can convert an output current into a sensing voltage, where the charger outputs the output current to the USB. The current level detector can output a detection signal according to a level of the sensing voltage. The state machine can order that the voltage output unit adjusts a voltage between a first data signal pin (D+) and a second data signal pin (D-) of the USB. |
