to expand from a "kit" topic to roving power outage... my dorm years at the Univ of Florida were before central air conditioning...a window fan really aided sound sleeping... today, some form of personal battery powered fan (using your preferred re chargable cells) might be a consideration... additionally to provide some hot water, a 2gal pump up garden sprayer painted black could be placed in the sunlight to provide a little warm water for a quick shower...open flame cooking is most likely prohibited, but an Asian style flat stove outside in a court yard area could provide a hot meal or drink.. if the rolling blackout is announced transfer to any perishable food to a 7 day cooler
