When on longer road trips I always carry a portable tank of spare fuel just in case. Sure, I rarely need it, but it's been handy a few times.

This is out of California and nearby states where long stretches of emptiness are a regular occurrence. Back when I lived on the east coast I never did this as the population density is much higher.

And ya, when you are at some place like Crater Lake National Park, you don't really think too deeply about how the next gas station might be 100 miles out.

If I was going into the Australian outback, preparations are necessary, but running out of gas due to poor planning or unexpected situations is at least as common as running out of battery due to similar poor planning (or unexpected situations).

> Most gas-powered generators that your roadside assistance will come with provide 9.6 kilowatts and generate 240 volts. Inquire with your roadside assistance provider to know whether they offer a mobile charge. Often that not, they may be offering it.

Ya, they are coming with basically with a diesel generator that outputs 240 volts...which should give you 20 or so miles in 30 minutes?

Or towing (on a flatbed) to the nearest charger is an option if you can't bring power to the car.
