Abstract: Multi-functional power distribution unit transitionable between different configurations and form factors to perform various power storage and distribution functions. Conversion cap attaches to a top of an expansion battery to convert the expansion battery into the multi-functional power distribution unit. A three-point coupling arrangement safely connects two power connectors (such as spring-loaded) of the expansion cap to two terminals on the expansion battery. Slidable/rotatable handles provide a gripping area for carrying the device yet remain unobstructive when stored. The multi-functional power distribution unit expands a power capacity of a power supply and/or generator (e.g., a solar-based power generator) and/or charges the expansion battery in a first configuration with the expansion cap connected to the power generator. Upon disconnecting from the power generator, the multi-functional power distribution unit transitions to a second configuration providing a standalone power supply (e.g.

Abstract: A filtration cooler system includes a cooler reservoir having a reservoir receiving portion, a lid coupled with the cooler reservoir, a drip tray, a filter bucket, and a filter. The drip tray is received by the cooler reservoir such that the drip tray is disposed over the reservoir receiving portion. The filter bucket has a filter receiving portion operable to receive water. The filter bucket is received by the drip tray when the drip tray is disposed over the reservoir receiving portion. The filter is received in the filter bucket. The filter filters the water in the filter bucket such that the water passes from the filter bucket into the reservoir receiving portion. The drip tray and the filter bucket can be nested such that the drip tray and the filter bucket fit within the reservoir receiving portion when the lid is closed over the cooler reservoir.
