18v 40W 630*370*3.0mm Dual USB Interface PET Polysilicon Solar Panel with Line + 4 Suction Cup Set for 12V Battery Charge Camping Outdoor Work

Descriptions: The main function of this product is to charge the 12V battery of the car, moto, and motorboat or most of the 12V lead-acid and lithium batteries. The trickle charging will be helpful for extending the battery life through its current is small. The charging method is not only energy saving, maintain battery life, but also can meet the needs of some small capacity car audios, which it's very suitable for outdoor work, travel or camping. Specifications: Dimension: 630*370*3mm No-load Voltage: 18-23VDC Load Voltage: 12V Output Current: 2120mA(max) Gross Weight:1250g Applicability: 12V car,moto and motorboat batteries and so on. Conversion rate 19.6-20% Output voltage 18v 2120ma & 5V 2120ma Operating Instructions: 1. Please position the 18V40W solar panel toward the sunshine first, the red light of the cable will indicate the current output. 2. Put it on the workbench in front of the car dashboard, the sunlight absorbing ability of this way is not strong. But if you set the two elastics at the back of the product on the sun visor of the car, the sunlight absorbing ability will be better. And it is the best to fix the sucker in the windshield or other placed which will absorb the sunlight easily. Warm Tips: 1. Please make sure the positive and negative terminals of this product are connected with the charged product's positive and negative terminals before usage. 2. Please do not try to modify the PCB circuit unless you are a professional technician. And we are not responsible for such a result. 3.The best working time: 9:00-17:00 (mainly for sunlight weather). 4. The charging current of the 18V40W solar panel is about 2120mA, relatively small, which is intended to extend the battery life and emergency charge usage. Please choose other higher current products if you want a faster-charging speed. Note: 1. Please don't scratch the surface of the solar panel with a sharp object. 2. Please make the solar panel exposed to direct sunlight to ensure the best charging speed while it is charging. 3. Please don't place the charger on a rainy day, or it will lead to a short circuit. 4. The 18V 20W solar panel charger is built with an Anti-flow resistance preventer inside,it will not occur the backflow phenomenon. Package Included: 1 x Soar Panel with Cables 4 x Sucker
