I use a small "solar generator", mine is from Bluetti but so many different manufactures to choose from. You can plug many devices into it so it will serve multiple purposes. Look up HOBOTECH on YouTube, a great source of information on all off-grid devices. Best luck

How about a response from a guy that needs no batteries to take a photograph? Take fewer images. I was at a week long Death Valley workshop last month with nine digital shooters. I shoot 8x10 large format that has spring activated shutters and use an analog light meter. As a comparison I came home with eight sheets of film and four glass plates to develop, they each shot hundreds of images.

I know to each his own. I enjoy the slow contemplative process that allows me to get into the moment and feel an image. Just suggesting that you try this when shooting digitally. It definitely would help solve your battery issues.

I also agree about the slow, contemplative process. After 33 years using film exclusively, and 10 more years testing the waters with digital but not ready to make the jump, I can say that for the last 12 years of digital-only has not changed my shooting style - slow and contemplative - in the least. But it has added some higher performance (up to 24 fps) shooting with autofocus, that has made certain shots that weren't even on the radar 12 years ago, finally possible. Postage stamp sized SD cards can hold thousands of images - and don't require water and chemicals or a darkroom - so I am free of that hassle.

I'm surprised that no-one has mentioned a spare battery....
My camera battery charger and the spare battery both live in my camera bag.
I hadn't used my camera for probably 4 or 5 weeks, and when I put it away the battery in the camera had already been well used. After a day or so of shooting, it was drained. Replaced it with the spare, and happily carried on, even after that spare had been in my camera bag for so many weeks.

Here Walmart sells a car start battery, LIon, that has a usb port, that might help, Harbor Freight sells car starter pac with a cigarette port, that also might be the answer.

I have not read all the comments, but my first inclination is to have a small wiring change to the vehicle to have the usb ports hot all the time.

The OP said he carries several additional camera batteries. The problem is charging them upon depletion.

I use a charge storage device, I do not know the correct name for this kind of device, but the answer from radiojohn describes what I am talking about. I pre charge it and it holds enough electricity to recharge my camera battery when it runs out. The devices are not too expensive and are primarily used to recharge a phone battery when it runs out. It usually takes several hours to recharge a camera battery. The "brick" device I use is charged with a normal usb charger and when I need to recharge my camera battery I plug a usb cord into the output side of this precharged "brick" and connect it to the 3rd party charger. There are quite a few 3rd party chargers on the market. I bought mine at my local camera store and made sure it would work. Mine uses only + and - poles which can be positioned to contact the camera battery's + and - poles. Hope this helps.

As camera batteries are usually Lithium Ion they need to be safely charged with the charger intended for the battery. DO NOT charge + to + and - to - with any fixed voltage source. You will be asking for a fire.
If your charger plugs into 120 vac wall power you will need an inverter powered from the storage source. If your charger is usb powered, you will need an adapter to reduce the storage battery voltage to usb (5 v) with a usb outlet. Be aware that lithium batteries require very specific voltage control trough rhe charge cycle. Using just any third part charger without that protocol may at best ruin your battery or in worst case start a lithium fire.

Yes, I had the same thought. My wife's car has the same issue, which I thought was really lame and unusual. I guess not as unusual as I thought, but remains very lame.

Still, for me, being out in the cold wilderness for days with no phone service I would want a backup battery setup that could get the car started if the car battery died, and double as a charging station for various devices, like a cell phone or camera etc. The $70 Harbor Freight unit I referenced on page one would be something to consider, among a slew of other similar devices.

Also the devices listed by E.L.. Shapiro would be perfect for his needs if he was only worried about his camera batteries possibly dying expectantly.

Does the vehicle need to be running for power or is the power outlet switched by the key? You should be able the charge camera batteries with a USB charger by using a 12V to USB adapter with the engine off.

If the power outlet is switched by the key I would wire up an auxiliary cigarette lighter /power socket to the battery that stays hot. They plug your USB adapter and charger in there.

This should get you off the power grid for weeks at a time.
