Rapid charging apparatus

A rapid charging apparatus including a first connection unit, a second connection unit, and a rapid charging power transformation unit is provided. The first connection unit is coupled to a connector with a power. The rapid charging power transformation unit is coupled to the first connection unit to receive a voltage of the connector and to provide a first voltage and a second voltage. The first voltage ranges from 3.2 V to 1.1 V, the second voltage ranges from 2.7 V to 0.6 V, and a voltage difference between the first voltage and the second voltage ranges from 0.5 V to 0.8 V. The second connection unit is coupled to an electronic device and the rapid charging power transformation unit so as to transmit the first voltage and the second voltage to the electronic device.
