Are you worried about your phone running out of battery while enjoying outdoor activities? Are you tired of carrying inconvenient power banks? Our solar power banks can meet all your needs. Today, power banks have become a necessity for people who love to go out. We have upgraded our solar panels to expand the sunshine receiving area and increase the charging speed. This feature is particularly useful for outdoor enthusiasts and travelers. Our solar power banks come equipped with dual USB ports that can charge two devices simultaneously. Moreover, the dual LED high-illumination lights make it easy to deal with power outages or dark nights. Our solar charger has two charging methods. First, it can be charged using a micro USB cable, with a maximum input current of 2A. Second, it can be recharged via sunlight, making it an ideal emergency power supply for outdoor activities.
