No association, but something like this is "the right answer", IMHO: https://www.cargenerator.com/pages/use-your-car-as-a-backup-...

1) if you're permanently modifying your home or electric panel you're over $1k. (General Motors "Vehicle2House" is ~$10-20k for hardware + installation... an EXTREME investment unless you plan on regular "emergency" usage of it)

2) if you're buying some portable solar panel "battery boom box" you'll likely run out and the folding solar panel it comes with is more gimmick than reliable

3) if you're buying a "real" gas/diesel generator, you have to run it + change the oil every 6 months otherwise it might not start in your emergency situation

...just buy a thing that clips to your car battery and dangles out the front hood of your car!

You already maintain your car every 3-9 months, you already (should) have at least 1/2 tank of gas at all times (especially in a weather / outage situation), you can generally idle your car for at least 2 days off a tank of gas in an emergency, and if this thing can charge your phone/battery packs, keep your fridge running (kindof?), and run a small space heater overnight...

It makes soooo much more sense to buy a $500-$1000 emergency accessory that piggybacks off the car you already maintain than trying to stand up a whole extra distribution mechanism for "survival-ish power, maybe 1-2 times over 3-4 years".
