If you’re the type that likes to get rugged but has a panic attack when your phone is on 3%, you might want to consider the RokPak Charger for your backcountry kit. The battery can charge a smartphone 8 times over while supplementing on solar and keeping your devices dry and protected from impact. You could piece out a pelican case, a portable power bank, and a little solar cell for a similar result but at $179 price tag I doubt you could do it with the same quality and ease of use. 
Here’s how the company describes this world’s first combination of products:
“The Pioneer Series is the world’s first and only product to combine solar charging, battery charging and rugged waterproof storage into an all-in-one lightweight solution. Built for the toughest conditions passing Military Standard 810G drop testing and IP67 waterproof certification, RokPak gives you the freedom to go anywhere in the world with power. Dual smart USB charging ports with 2.4A output (each) allow for fast charging of ANY USB device including smartphones, tablets, cameras, GPS, etc. with the 12,000-mAh lithium ion battery.”
