For short trips, lithium-ion batteries to recharge your camera/phone/GPS make more sense. For something like the Appalachian Trail where batteries aren't going to last the whole trip, a solar charger would be needed although it won't replace batteries completely because some days are cloudy. On average, with current technology how many MAH of battery power would one need before a solar charger becomes more weight-efficient?
