My 2nd battery is hooked up to the car and charges while i drive and cuts off if it gets too low. It lives permananetly in my canopy.
The 3rd battery is encased in a cheap battery box that i pull out of the canopy and sit next to my camping fridge for days on end. Powers lights and my phone.
I've also got a Milwaukee charger that comes with a 12v cig socket that can charge up my tool batteries....which i use for lights, chainsaws, radio, whatever.
With that setup, even if overcast or raining, i can pretty much be self sustaining for....as long as i need to be. Recently i set up the solar panel underneath our gazebo (in the shade, while it was raining) and it was still getting enough sun to charge my battery.
I also have a 1500W invertor i can use to get 240v plugs if required.
So...if i can live outdoors with that setup, surely it could help me charge a car. Not sure what type of current draw they take, or how much power storage is typically on board, but to me it seems like a half decent alternative to hooking up to the grid.
Obviously, you could get bigger outdoor solar panels pretty easily to beef up the system as well. They are relatively cheap.
