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.
