I had the misconception that it would store power energy and allow me to charge my devices whenever I needed. However, I soon realized that it only charges when fully open in direct sunlight. This limitation was quite inconvenient for me as I was hoping for a more flexible charging solution.

Another drawback I experienced was that when I placed my phone in the pouch provided, it would get too hot. Additionally, there was no indicator to show whether the device was charging or not. Despite these issues, I did appreciate the ability to charge my battery and phone when off the grid. However, I would recommend using this solar charger with caution, as its effectiveness can be affected by varying sunlight degrees and the presence of clouds.
