["100W Solar Panel 12V System Set"]2 Pcs 50W Solar panel kit ideal for charging 12V system batteries, you will receive 2 pieces of 50W Mono Solar panels, 1 piece of 10A PWM charge controller, 1 piece of 5-foot cable with alligator clips, and 1 piece of 5-foot cable with O-ring connection. The 10A solar charge controller is compatible with various types of batteries, such as lithium-ion battery, lead-acid battery, and lithium-iron-phosphate battery. ["2x50W Monocrystalline Solar Panel With"]Dimensions: 570*470*17mm (22.44*18.5*0.67 in). Weight: 3.1kg (6.83lb), Operating temperature: -40°C to +80°C, lighter and smaller. *The issue of USB not working is related to two points: 1. If the battery is not connected or the battery level is too low, the USB will automatically shut down. USB power comes from the battery. 2. The load voltage of the lights used is not 5V or the load power is too high. The voltage at the output end of the load is the same as the battery voltage.
