The portable solar 12v battery charger uses the most powerful single crystal panel to charge your device by using solar energy and integrated batteries. This portable device is magnetically foldable, very effective and durable, for your next outdoor adventure, even if you carry multiple gadgets, you only need to connect three solar panels together to triple the output.
In addition to the solar components that continuously provide power, the remaining main components of the power supply system are solar charge controller, battery, inverter, cabinet, and structural parts.
(1) Solar cell components: Solar cell components are the core part of the solar power supply system and the most valuable part of the solar power supply system(Portable Voltage Regulator: Computer Voltage Regulator). Its function is to convert the sun's radiant energy into electric energy, or send it to the storage battery for storage, or drive the load to work. The quality and cost of solar cell components will directly determine the quality and cost of the entire system.
(2) Solar controller: The function of the solar controller is to control the working state of the entire system, and to protect the battery from overcharge and over-discharge. In places with large temperature differences, a qualified controller should also have the function of temperature compensation. Other additional functions such as light control switch and time control switch should be optional options of the controller.
(3) Batteries: generally lead-acid batteries, nickel-hydrogen batteries, nickel-cadmium batteries, or lithium batteries can also be used in small and microsystems. Its function is to store the electric energy supplied by the solar cell module when there is light, and then release it when needed.
(4) Inverter: The current generated by the solar cell is direct current, which is charged into the storage battery for storage. The inverter converts direct current into 220V alternating current for various loads. In particular, in general, the inverter must be connected to the battery for use. If it is directly connected to the solar battery, it will not work normally due to the unstable sunlight environment.
(5) The box body and other structural parts: Mainly the place where the above equipment is placed. The size of the box body is different depending on the product. At the same time, depending on the difference in product functions, there may be different structural parts such as DC output and multi-hole sockets.
The 12V 40A charger can quickly charge your device, whether it is charged by solar or USB, it can store up to 2000 mAh of electricity.
The portable solar 12v battery charger can charge low-power devices such as smartphones, flashlights, speakers, tablets or external battery packs(step down voltage converter: portable step down transformer). The panel will charge the battery during the day, while you can charge the gadget at night. The solar battery pack weighs only 0.52 pounds and 0.7 pounds, and the size when unfolded is only 2.9 × 9.6 × 1.2 inches, which is much smaller than the same solar panel chargers with the same capacity and rating on the market. Each unit is equipped with a protective cover, which can also be used as a magnetic buckle to bind the rolled-up panels together.
The solar 12v battery charger can automatically adjust its energy output to provide the correct power source, thereby optimizing the charging quality and maximizing the total battery life. No overcharge or overload phenomenon. The LED light will light up as an indicator light, which can help you more easily determine and modify the solar panel to the proper charging position.
