descriptionFeatures of solar panels: This product adopts a new conversion method, in the case of the same area and power, the working current of solar output doubles. The two-way voltage output of solar energy is divided into 18v&9v or 12V&6V by shifting. Under the same area of power, the output current of the solar panel doubles, and it can charge the car mobile phone computer and the battery in the same environment. Improve efficiency and double the charging speed. The product is flexible and foldable, and can be affixed to a smooth surface with a certain amplitude (such as the roof of a car) Specifications: Material: PET + polysilicon battery Waterproof rating: IP65 Solar energy conversion rate: 20% Pmax: 60W Vpmax: 18V /12V/9V/6V NOCT ( Nominal working battery temperature): 40-85 C Size: 440x200x2.5mm Maximum solar input: 12V Battery up to 23V 24V Battery up to 46V Balance: 14.4V/14.2V/14.6V Floating charge: 18V/12V/9V/6V/5V (Adjustable by default) USB output voltage: DC output: 18V 2.81A USB output: 5V 2.
