For my last camping trip, I decided to try an off-grid solar system, as I've often faced the problem of not having enough power for gadgets in remote locations. I chose a kit from https://www.sungoldsolar.com that included compact solar panels and portable batteries. This solution turned out to be great! The panels charged the battery throughout the day, and by evening, I had enough power to charge all the devices I needed. This was perfect for long hikes and camping in the mountains.
