I routinely use my phone to find details of the terrain over which the plane is flying. I have maps for the whole world downloaded, and the GPS is likely to work when I sit by the window.

Is there something suited for charging at -15C (around 5F)?
You can charge LiFePO4 below 0C, provided the charging current is at 0.05-0.1C. This is about what you get from a hub dynamo anyway w/o special provisions. I have used 26650.

Sorry for the slow response. I am traveling, fortunately, with a Harvester on my Brompton. I put it into a pocket of this
bottle pouch, together with USB cables. The pouch is lousy, but good enough for the purpose. The cable from the dynohub comes in through a hole in the bottom of the pouch. I melted it out with a soldering iron, I think. I modified the zipper to open from two sides. Usually, the pouch is closed, and I open it slightly when charging the phone or something else. Through the opening, I can see the control LEDs.
