I'm doing this review while lying on a yoga mat. on the grass . Departing July 4th. Took my wife on a picnic. Super strong solar panel. Efficiently charge a 330W battery. Generated from 5 percent to 17 percent in just 25 minutes. My mini fridge runs on 30 watts. No problem. . Like the buckle design instead of the sticker. More durable on the side All kinds of adapters are suitable for whatever you need. It comes with a stand holder on the back of the panels. You can open it to direct the sun in any direction. I even tried to put the whole fairing on the roof of an SUV. That works great. You need that in a car. Whatever an emergency or family outing. . Very happy with it so far. The water resistance has not been tested. But I'm pretty sure it will keep the rain out. Purchased after watching a few solar tutorial videos on YouTube. I believe 100W is the most popular. Good solar panel highly recommended! Happy 4th of July everyone. Stay Safe ❤️ God Bless America.
