The Amazon reviews say it charges at 200 mA/hour in full sun, 130 mA/hour on a typical hike. It holds 5000 mA-hours. The math is not encouraging.

Bright sunlight: Good for solar charging
Bright sunlight: LCD and OLED require much more power to display legible image

The battery will charge the USB device at 10 watts, but the solar panel will recharge the battery at only 1 watt.
Needs a solar panel the size of a 17" laptop to be effective.
