Solar Panel Feature: This product adopts a new conversion method to double the working current of solar output with the same area and power. The two-way voltage output of solar energy is divided into 18v & 9v or 12V & 6V by shifting gears. Under the same area of power the output current of the solar panel doubles making it possible to charge cars mobile phones computers and batteries in the same environment. Increased efficiency and doubled the charging speed. The product is flexible and foldable can be attached to a smooth surface with a certain amplitude (such as the car roof) Specifications: Material:PET+Poly silicon cell Waterproof rating: IP65 Solar energy conversion rate: 20% Pmax:60W Vpmax:18V/12V/9V/6V NOCT(nominal operating cell temperature):40-85 C Size:440x200x2.5mm Max solar input: 12V batterythe highest 23V 24V battery when the highest 46V Equalization:14.4V/14.2V/14.6V Float charge:18V/12V/9V/6V/5V (defautadjustable) USB Output voltage: DC output: 18V 2.81A USB output: 5V 2.8A (max) TYPE-C output: 5v 2.8A Self-consume:
