Power & Electronics converts power-bank labels into real 5-volt output, derates lithium-ion by freezing temperatures, evaluates solar harvest against peak-sun hours and predicts headlamp runtime on every mode.

Weather & Navigation includes Naismith hike time with daylight, NWS wind chill, flash-to-bang lightning timing and the 30/30 rule, 1-10-1 cold-water immersion, lapse-rate summit temperatures, a DD/DMS/UTM/MGRS coordinate converter and a timed Morse SOS signaler.

Trip & Gear finishes the plan: Pandolf calorie burn and food weight, pack base-weight analysis, seven smart checklists, trekking-pole and sleep-system sizing, a ten-point campsite score and a printable emergency trip plan for search and rescue.
