Question 1

Can you also charge  fast with electricity then take camping and  maintain with solar?

Accepted Answer

Quote from manufacturer in the most popular question:
"If you use 1A wall charger, it will take 18-25 hrs to be fully charged"
Claims to charge at 1A if in full noon-day (straight overhead) sun in a clear sky.
SO.  If you can charge it 4 hours a day from 10:00 AM - 2:00 PM it will take 25hrs / 4 = 6+ days to recharge to full capacity from dead.  
Probably about right if exposed to sunlight all day long, as if hang from backpack, it will not face sun directly for optimum charging, and if hiking won't always be facing the sun, and you might be walking under trees.
However, it beats no solar charging.
Bottom line is if you are a device junky and just have to be connected to big tech around-the-clock in the big city while allegedly enjoying the outdoors it might not meet be your cup of tea.

Question 3

How does this changer perform in colder temperatures?

Hi, glad to get your inquiry. Because it's in the winter, so the solar charging speed will slower than that in the summer day because of the decrease of sunlight intensity.
