What are class DC power tools?
The power tool has no battery pack, powered by a DC adapter, such as some DC screwdriver; or, 12V or 24V, powered by a cigar lighter in the car. (for example, car impact wrenches)
Remarks: if the power tools are powered by AC, but the internal use of DC motors, using isolated transformers for voltage reduction, rectifier to direct current, not DC tools, or communication tools.
Electric tool is used as a power supply for battery pack, a battery pack charger for charging, some can not have a removable battery pack, battery pack is in need of direct internal tools, tools for charging, simply say, like the same mobile phone.
