All you need is a portable generator. Except they pollute more than the cars the electric vehicles are supposed to replace
Small generators are particularly toxic
"The smallest portable generators less than 50hp also are generally exempt from air district rules."

"Portable generators, whose engines each emit as much carbon monoxide as approximately 450 cars, are especially common culprits."

"Carbon monoxide reacts with hydroxyl (OH) radicals in the atmosphere, reducing their abundance. As OH radicals help to reduce the lifetimes of strong greenhouse gases, like methane, carbon monoxide indirectly increases the global warming potential of these gases."

"Engineering Researchers Find When Power Goes Out, Pollution Rises. Our results suggest that, in some countries, air emissions resulting from reliance on backup generators can be even larger than annual emissions from centralized power plants."
