100% brand new and high quality Features: Flexible and foldable enough that can be attached to a smooth surface with a certain amplitude ,such as the car roof. Adopts a new conversion method to double the working current of solar output with the same area and power. Under the same area of power, the output current of the solar panel doubles, making it possible to charge cars, mobile phones, computers. Batteries in the same environment,and increased efficiency and doubled the charging speed. Build-in industrial micro controller. Fully 4-stage PWM charge management. Build-in short-circuit protections, open-circuit protections, reverse protections, over-load protections. 60W Dual USB Solar Panel only,not including other accessories in the picture demo Specification: Material: ABS Float charge: 17.4V USB output: 5V/3A Self-consume: <10mA Discharge stop: 11.4V Voltage:12V/24V Max solar input: <30V Current: 10A Rated working current: 20A Discharge reconnect: 10.2V Working temperature: -35~60 Output voltage: 12V/24V Automatically distinguish voltage Dimensions: app.44x19cm /17.32x7.48inch Color: As shown Type: Without Controller; With 10A Controller; With 20A Controller; With 30A Controller; With 40A Controller; With 50A Controller Quantity: 1 pc Note: Please allow 0-1cm error due to manual measurement. pls make sure you do not mind before you bid.
