Abstract: A power distribution device and a transportation device having the power distribution device are provided. The power distribution device includes a housing, a precharging circuit module, and a main positive circuit module. The housing has a mounting cavity. The precharging circuit module is configured to precharge a capacitor element in an electrical appliance, and includes a precharging relay. The precharging relay is connected with the housing. The main positive circuit module is configured to be closed after the precharging circuit module is opened. The main positive circuit module and the precharging circuit module are stacked in the mounting cavity in an up-down direction. The main positive circuit module includes a fuse and a main relay core. The main relay core is connected with the housing.
