1. An adapter for connecting a multi-voltage battery pack to a power tool, the multi-voltage battery pack provided with a multi-voltage battery interface and configured to output at least two different voltages, the power tool provided with a power tool interface and detachably coupled with a single voltage battery pack, the single voltage battery pack configured to output only one voltage, the multi-voltage battery interface of the multi-voltage battery pack being not couplable to the power tool interface of the power tool, the adapter comprising:
a housing;
an input port disposed in the housing and provided for electrically and mechanically coupling with the multi-voltage battery interface of the multi-voltage battery pack; and
an output port disposed in the housing an provided for electrically and mechanically coupling with the power tool interface of the power tool, the output port electrically connected with the input port;
wherein the power tool can be powered by the multi-voltage battery pack when the multi-voltage battery interface of the multi-voltage battery pack is coupled with the input port of the adapter and the power tool interface of the power tool is coupled with the output port of the adapter, wherein the input port is provided with a switching mechanism matched with the multi-voltage battery interface of the multi-voltage battery pack so as to change the output voltage of the multi-voltage battery pack by changing the connection state of the switching mechanism between a series or parallel supply of voltage from the multi-voltage battery interface.
