For the guys who camp, how do you keep your camera batteries charged? I'm going camping, my first time, for 3 days. I have 2 batteries but I'm afraid they will run down before the 3rd day. I'm planning on shooting the night sky which usually drains my batteries pretty fast
I don't want to buy more batteries. 1Ds MK II batteries are large and expensive
How do I charge them? Thanks guys!
Fingers crossed for hookups around the camp site.
