Probably a relatively narrow topic given the still low representation of battery electric vehicles in the market, but I came across this video of what a YouTuber (no affiliation) did in a recent power outage in the Pacific Northwest (USA) to help power her house (in part) and keep her channel up. Interested to hear what everyone thinks.
