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).
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.
1.Please don’t scratch the surface of the solar panel with a sharps object.
2.Please make the solar panel exposed to direct sunlightto ensure the best charging speed while it is charging.
3.Please don’t place the charger in the rainny day,or it will lead to a short circuit.
4.The 18V 300W solar panel charger is built with an Anti-flow resistense preventerinsdie,it will not occur the backflow phenomenon.
The main function of this product is to charge the 18V battery of 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 though 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.
18V car, batteries and so on.
