Various aspects of hanging tool support devices and objects that couple thereto are shown. In various embodiments, the hanging tool support devices described herein are configured to be used in conjunction with moveable walls, such as for a utility bucket. One or more of the objects that couple to the hanging tool support devices are also configured to engage with units within a modular tool storage system.

A power distribution device that couples to storage units is provided. The power distribution device a battery charger that indirectly charges batteries, such as for personal electronic devices. The device includes a top panel with a recess that receives the personal electronic devices. The device also includes interface components to couple the device to a modular tool storage unit.

A stackable power supply device, container or unit is provided. The power supply device includes an energy conversion module, such as a solar panel. The power supply device includes several power outlets, such as an interface to recharge rechargeable batteries for power tools, an electrical outlet, and a battery to store energy generated by the solar panel. The power supply device is stackable within a modular storage system.

A tool organizer provides a modular building block to allow assembly of organizers to hold multiple tools of a desired quantity. The organizers have a front tab that fits into a rearward receiver of another organizer to allow multiple organizers to be assembled together to make a multi-tool organizer block. The organizers employ tool receiving channels with curved profiles to allow tools placed therein to be aesthetically aligned for an ordered appearance.
