摘要： A portable lighting device includes a lighting assembly, a switch assembly, a control module, a power supply, a power recognition circuit, and a power conversion circuit. The control module is configured to control the lighting assembly to light up according to an indication of the switch assembly. The power supply is used for supplying power to the lighting assembly and includes a battery pack and an external power supply. The power conversion circuit is used for converting a power of the power supply into a power output adapted to the lighting assembly and the control module. The power recognition circuit is configured to selectively output the power of the battery pack or the power of the external power supply to the power conversion circuit.

摘要： A power tool includes a power tool body. The power tool body is configured to be adapted to at least a first battery pack having a first nominal voltage and a first output terminal set and a second battery pack having a second nominal voltage and a second output terminal set, where the first nominal voltage is different from the second nominal voltage. The power tool body includes a first input terminal set configured to be selectively electrically connected to one of the first output terminal set and the second output terminal set to supply power to the power tool body.
