Abstract: A power distribution device and a transportation device having the power distribution device are provided. The power distribution device includes a housing, a pre-charging circuit module, and a main positive circuit module. The housing has a mounting cavity. The pre-charging circuit module is configured to pre-charge a capacitor element in an electrical appliance, and includes a pre-charging relay. The pre-charging relay is connected with the housing. The main positive circuit module is configured to be closed after the pre-charging circuit module is opened. The main positive circuit module and the pre-charging 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.
