I have a Crappy Tire (Canadian Tire) Eliminator 800

That sucker will keep you in touch with the world. Or power a 13W light for a long while. And, you can charge one to full capacity from your vehicle in several hours. Or from a generator for SFA loss while the gennie is running other things.

I highly recommend them. Unfortunate that the price of them has gone up in the past while. But, since I make my living by being on the world wide communication networks, I gotta have em.

Right now, I gotta split some more kindlin for the stove. Keeps me warm.
