You can charge it with solar and they already have a 12v socket and a built-in inverter. They even have a charge controller so you won't have to worry about overcharging, plus they come with maintenance free gel or AGM batteries. You can usually get them pretty cheap nowadays too, depending on the size. $50 wouldn't be unreasonable for the size you need, especially if you got it used.
Aside from my regular panel array, I have a small 7 watts of panels that go directly into one of these power packs. I charge my GPS, 2 cell phones, 2-way radios, Nintendo DS and 2 Nintendo Wii controllers. I usually charge at least one item every day or two and between all of these things, I've never had a low battery.[ Parent ]
