I bought this solar panel for my car during this pandemic, barely drive my car due to work from home so the car battery dead every other week. Now this solar panel can charge my battery at anytime anywhere. I really love it!
it is easy to use，i just set up it by following specification. The solar charger is so efficient that I can quickly fill up with the appliances I want to use, like my cell phone. Is environmental protection.
