Review: So far so good - This came in a 2 pack deal with the larger panels that I originally wanted. Now I wonder if I didnt need the larger ones. This one seems like it will charge my batteries for extended camping trips just fine. Just keep adjusting it to be perpendicular to the suns rays and it will charge up your stuff. Seems well built
Review: Does the most important thing. - Just received this product, so have not had much time to use it, but out in the July sun today it charged my iPhone 10% in less than half an hour, so it does what I needed done.

### ⭐⭐⭐⭐⭐ Does the most important thing.
*by J***R on July 8, 2024*

Just received this product, so have not had much time to use it, but out in the July sun today it charged my iPhone 10% in less than half an hour, so it does what I needed done.

### ⭐⭐⭐⭐⭐ 15 minutes 12 percent increase
*by G***S on May 16, 2024*

It was a sunny afternoon so I decided to try this out. I put it out in my backyard at the 90 degree angel facing the sun. My Samsung phone was at 70 percent but when I finished setting this up it showed 69 percent. I plugged it in for 15 minutes and when I returned my phone was showing 81 percent. I did not think it would do that but it did work as intended. Note I did use my own phone cable to attach from the usb a port to my phone plug.
