Something like this should do. It's cheap chinese stuff, but it does the job for relatively cheap. No solar charger will charge your phone as fast as a wall outlet, but it does just fine for me if I leave it in the sun about 5 hours.

Here are some of them you need in camping:
Hi, it has only two USB ports for the outputs, which is exactly the same to [the one I got it from Suaoki] (https://www.amazon.com/Portable-Foldable-Mono-Crystalline-Universal-Technology/dp/B0142TA8UG). Great power for the size and using the Sunpower cells makes it superior!
Also, the one is able to fold up into a compact unit - but can be tricky to re-fold to get the velcro in the correct orientation for securing the cover.
I used to have this 25W solar charger. It has 4 very nice solar panels making it very efficient, it's capable of charging up to 2 devices at the same time. It has a magnetic latch that automatically keeps the charger closed and the solar panels protected. There also comes with 4 carabiner and a micro USB cord.
