Keeping Your Tech Alive at -40 Degrees
In the extreme cold near the Mount Everest summit, a full battery can die in seconds. For a Mount Everest expedition, keeping your camera, radio, and headlamp running is a constant battle against physics.
Never keep electronics in your outer pack. Batteries must be kept in the internal mesh pockets of your down suit, using your body heat to stay functional for the Mount Everest summit push.
Standard alkaline batteries fail instantly at altitude. Professional Everest trekking groups and expeditions only use Lithium-ion, which handles sub-zero temperatures significantly better.
Taping a small chemical hand warmer to the back of your camera battery compartment can squeeze out those extra minutes needed to capture the sunrise on the Mount Everest summit.
Power is a finite resource on the mountain. Use these hacks to ensure you have enough juice to document your Mount Everest expedition success.
