Abstract

This invention discloses an electrical energy transmission apparatus. The electrical energy transmission apparatus includes an input component which is connected to a direct current (DC) energy storage component, an output component which comprises an alternating current (AC) device interface used to connect an AC device, and an adapter component which transfers electrical energy from the input component to the output component. The adapter component comprises a DC driving unit and an AC driving unit. The DC driving unit converts energy of the DC energy storage component into a DC power. The AC driving unit converts energy of the DC energy storage component into an AC power. At least one of the DC driving unit and the AC driving unit is connected to the AC device interface.

First claim

1 - 30 . (canceled)

31 . A portable power supply for use with a plurality of different power tools, the portable power supply comprising:
a main body; a battery pack detachably connected to the main body with the battery pack defining a first power supply mode when removed from the main body for powering a first power tool of the plurality of power tools; and a wearable component detachably connected to the main body; the main body defining a second power supply mode when the main body is removed from the wearable component and the battery pack is connected to the main body for powering a second power tool of the plurality of power tools; and the main body defining a third power supply mode when both the wearable component and the battery pack are connected to the main body for powering a third power tool of the plurality of power tools.

32 . The portable power supply according to claim 31 , wherein the main body comprises an energy output port that provides at least one output voltage different from an output voltage of the battery pack connected to the main body when the portable power supply is in the second power supply mode.

33 . The portable power supply according to claim 31 , wherein the main body comprises an energy output port that provides at least one output voltage different from an output voltage of the battery pack connected to the main body when the portable power supply is in the third power supply mode.

34 . The portable power supply according to claim 32 , wherein the energy output port provides at least one output voltage different from the output voltage of the battery pack connected to the main body when the portable power supply is in the third power supply mode.

35 . The portable power supply according to claim 31 , wherein the main body comprises a DC output port and an AC output port, with the DC output port connected to a DC device and with the AC output port connected to an AC device.

36 . The portable power supply according to claim 31 , wherein the second power tool is a push power tool, and wherein the main body is mounted to the push power tool so that the weight of the battery pack and the main body are supported by the push power tool.

37 . The portable power supply according to claim 36 , wherein the push power tool is a high voltage push power tool.

38 . The portable power supply according to claim 31 further comprising:
a bag body covering the battery pack; and
a cover operatively opening and closing the bag body, the cover including a waterproof layer.

39 . A method of powering a plurality of different power tools using a common portable power supply having a main body, a battery pack, and a wearable component, said method comprising the steps of:
removing the battery pack from the main body and connecting the battery pack to a first power tool of the plurality of power tools to define a first power supply mode; removing the wearable component from the main body, connecting the battery pack to the main body, and connecting the main body to a second power tool of the plurality of power tools to define a second power supply mode; and connecting the wearable component to the main body, connecting the battery pack to the main body, and connecting the main body to a third power tool of the plurality of power tools to define a third power supply mode.
