Is there solar power charger for cell phone?

I have seen emergency flashlights that use solar power to provide light, radio and some even have USB charge ports. But I’ve also read that they can fry electronics. So I want to know is there a safe solar-powered charger in the market that can charge a cell phone in emergency? If someone already using this than please suggest so that I can order it online.
