I guess you would often get closer to the true output of the 20+W solar panels, at least during summer daytime. I haven't done extended hiking or similar, but I expect "phone off" (and maybe a usb battery) is pretty competitive as a solution, with charging when it happens to be available.

I’ve done a lot of backpacking and tried various approaches inluding solar panels but I’ve settled on bringing a good 10,000mah rechargeable usb battery pack. With this I can keep my garmen inreach mini, iPhone and headlamp charged for 5-6 days on the trail with a battery that weighs 6oz.
