Hi,
I would like to carry a power bank with me when I am out to the mountains. The main goal is to always have spare power to my phone when an emergency situation comes up (getting lost, accident, etc.)
Requirements:
- 3500-5000 mA capacity is enough, usually I do one or two day hikes
- water and impact protection is good to have, but not necessary, I prefer the lower weight products
- low temperature tolerance and discharge up to -20 Celsius
- high altitude tolerance and discharge up to 5000 meter
If you have any experience please share with me. After 2 hours of googling, I wasn’t able to find a proper device.
This seems to close:

Thank you
Attila
