Category context
Trail electronics are reviewed for battery realism, not brochure numbers. Cold mornings, GPS logging, and photo bursts drain faster than lab tests — we note what survived full hiking days and what needed a top-up at the hut. For Black Diamond Spot 400-R, apply the same lens: will you use it every day of the trip, or is it dead weight?
