This invention provides an electrical apparatus that includes a main body portion, a battery pack, and a frame portion. The main body portion comprises a converting portion that may convert electric power to one of light, wind, heat, and sound; and an outputting portion. The battery pack may detachably mounted on a battery holder provided at the main body portion, and may supply electric power to the converting portion. The frame portion may rotatably support the main body portion, and may define a first ground contact plane that can contact a ground surface and a second ground contact plane that can contact the ground surface at a different angle from an angle of the first ground contact plane. The main body portion may be rotatable relative to the frame portion without contacting the ground surface.

Electric device outputting light, wind, heat or sound

An engine-powered work tool includes: a shaft extending in a first direction; an engine at a rear end portion of the shaft; a fuel tank disposed below the engine in a second direction perpendicular to the first direction; and a stand fixed to the engine. The stand includes a fastening portion fixed to a front end portion of the engine, and a curved portion extending from the fastening portion and curving toward a rear end portion of the engine. The curved portion provides a lower end portion positioned downstream of a bottom end portion of the fuel tank in the second direction. The lower end portion has a distal end positioned upstream of the rear end portion of the fuel tank in the first direction, the distal end and the bottom end of the fuel tank defining a gap therebetween in the second direction.
