A portable power source is moveable over a support surface. The portable power source has a power supply, a frame at least partially surrounding the power supply, at least one wheel, handle having a user engagement member a and a clamping mechanism. The clamping mechanism moves from a first position to a second position. The clamping mechanism stops the wheel in the first position and allows the rotation of the wheel in the second position.

An apparatus for carrying construction panels in front and side carry configurations. The apparatus comprising a dolly frame, wheels, a dolly raise assembly so as to permit movement of a car and a load carriage along the dolly frame, a pivot mount hingedly mounted to the car and a load support, wherein the load support is pivotable relative to the pivot mount about a pivot axis between a front carry position and a side carry position. In another embodiment, an apparatus comprising a dolly raise assembly for controlled movement of a load carriage along the longitudinal extent of a dolly frame, and a panel lift fixable to the load carriage for lifting and orienting construction panels for attachment to a wall or ceiling. The panel lift having a lift frame with a panel carriage track, a panel carriage for supporting the panel, and a panel carriage raise assembly for controlled movement of the panel carriage along the panel carriage track.

A portable pop-up pet pen compacts into four corner post members for travel or storage. Each corner post member contains a base rail, top rail, and mesh wall portion. To open the pet pen, the base rails are pulled out and down, and each is connected to the base of another of the corner post members. The upper rails and web walls are then pulled up from the base rails, and are attached to the other corner post members. A top frame may support a roof or fly. The compacted posts can fit into a bag or case for storage. Two sets of four corner posts can be used to build a double-size pet pen.
