## Abstract

A disaster relief device is provided that integrates power generation, water purification, and communications into a single portable housing. The device includes a water treatment system having reusable pre-filters, multi-stage sediment filters, a reverse osmosis unit, and a UV sterilizer, together with a clean water storage tank mounted on a drawer for field servicing. An electrical subsystem incorporates a lithium iron phosphate battery pack in a fire-resistant enclosure, a charge controller, and a pure sine wave inverter. A hybrid solar array, including hinged and slide-out panels, provides rapid renewable power deployment, with guided cable carriers ensuring reliability. The housing is sealed to an IP66 rating, reinforced to function as a Faraday cage, and configured for transport with folding handles and airless wheels. Optional features include an integrated rainwater harvesting system, modular interconnection of multiple units for scaling capacity, and a satellite communications bracket for emergency connectivity.

## Claims
