Abstract: An adapter includes: a housing; a battery pack port for accessing a battery pack; a device port including multiple USB-type ports capable of accessing an electric device or a charging apparatus; a protocol matching module configured to perform a protocol handshake with the electric device or the charging apparatus; and a bidirectional DC-DC conversion module capable of converting electrical energy outputted by the battery pack into direct current power supply electrical energy or converting electrical energy from the charging apparatus into direct current charging electrical energy. The bidirectional DC-DC conversion module includes: a power switching element disposed on the power transmission loop between the battery pack port and the device port and capable of adjusting electrical energy in the power transmission loop; and a power control unit electrically connected to the power switching element and capable of controlling the conducting state of the power switching element.

Abstract: A power tool includes an output member for outputting power, a motor for driving the output member, a housing including a battery pack accommodating portion provided with a first battery pack accommodating cavity and a guide structure for guiding a battery pack to be inserted into the first battery pack accommodating cavity along a first straight line. The battery pack includes a basic housing portion provided with a first accommodating cavity, a first cell group disposed inside the first accommodating cavity, an extended housing portion provided with a second accommodating cavity, and a second cell group disposed inside the second accommodating cavity. The first cell group is at least partially disposed inside the first battery pack accommodating cavity, and the second cell group is at least partially disposed outside the first battery pack accommodating cavity.

Abstract: A power station and an adaptor are provided. The power station includes a battery pack and an adaptor. The adaptor includes a housing, a battery pack interface, a protecting frame for protecting the housing and disposed on the outside of the housing, at least one AC output port and at least one DC output port. The protecting frame includes a top seat at the top portion of the housing, a bottom seat at the bottom seat of the housing and a plurality of connecting bars respectively connected the top seat and the bottom seat. The output voltage of the DC output port is lower than the rated voltage of the battery pack.
