If you are in a flood zone and have lost power, and have a generator, may be an option. Not really eco-friendly or quiet, but will it work in a pinch? It's not a question of whether or not you can charge a Tesla, or any electric car, with a generator — or a portable unit in this particular case. It's a question of how much range you can get over a period of time, as well as how much gas you may need to burn to get add a reasonable number of miles. This is definitely something that many hardcore EV hardcore fans will frown upon for obvious reasons. Not to mention it's SO LOUD.
