If you’re in an area that gets power outages, get a solar cellphone charger.
Gas is too valuable and hard to get then to waste on charging phones.
That ‘hurricane high’ you get after the storm passes means clear hot days so you can keep those devices charged while you wait for the power to be restored.
I suggested that already, or a hand cranked charger or a camp stove charger.
My reply was in response to someone insisting that nobody used their cars to charge their phones when I know good and well that a lot of people do that.
