In the Arizona desert, it was blown away by a strong wind. But once I learned to tie it down and hold it directly to the sun, it worked really well. I'm glad I bought it. On the first day I charged 2 lithium launchers with it. And I needed that. I recommend the Schumacher jump starter. You can easily charge it daily. It keeps your phone charged. And start your car every day. This Schumacher launcher solar setup is a great start to getting solar power for your phone and car. Works very well. But regularly point it to the sun and tie it to something.
