This weekend we're going camping at Silverstone for the F1 where a considerable number of photographs are expected to be taken by yours truly. On a usual day at a motor racing event I take anywhere between 2-3000 images (spraying and praying) and that means in the evening I expect to be doing a fair amount of rejection editing. But how do you charge a laptop in a field next to a tent? Using some stuff I had lying around from my racing drone hobby, I'll show you how I am going to do it.
