My in-depth testing of all the best portable solar panels on Amazon for charging your phone, small or large powerbanks, and small power stations with a big emphasis on USB output and specifically USB-C Power Delivery (PD).

I purchased many of these panels out of pocket but was provided review units for free from Sunjack, Big Blue, Powerness, and Elecaenta but all opinions are my own. Recommendations are below:
