ABSTRACT:
A portable power device, light and fan including a chassis provided with a light, electric receptacle and switch structure, together with a motor fan unit forming a blower received in a housing supported from the chassis for pivotal movement about a tansverse axis with the blower housing including an outlet oriented above the portion of the chassis having the light, electrical receptacle and switch structure with the outlet in the blower housing being rotatable in a vertical plane about the pivot axis connecting the blower housing to the chassis. A carrying handle is attached to or otherwise provided on the assembly to facilitate its portability. The connection between the blower housing and chassis is uniquely formed by a venturi forming flange on each side wall of the chassis extending into and being closely received in an air inlet in each end wall of the blower housing, thereby forming air inlets for the blower housing and also pivotally supporting the blower housing from the chassis.
