When I saw this product, I think it as a normal charging instrument at first, for it has two USB ports. However, it is one kind of multiple usages item, also, power charging is one of its using aspects. It is the Solar Panel Regulator Charge, which can be used in various occasions. How does it work and working in what occasions? Let me tell you next.
It is very easy for thinking as the normal charging use instrument for it has simple appearance design, overall black color box and easy operating buttons that composed with it. Although it does not has nice looking, its shape design is unique. Most important, it has light weight and portable design. Dual USB design meets your need in charging two kinds of electronic devices at the same time. Besides, 30 x 50mm LCD display screen clearly shows you the statue of charging and discharging in time.
As one kind of professional instruments, it is a new intelligent solar controller, which was equipped with industrial-grade STM 8 microprocessor to control the charge and discharge process. As a result, it has perfect and liable battery charge and discharge period management. Moreover, it is characterized by high efficiency and low consumption by controlling the MOSFET of the ultra-low internal resistance with PWM. This controller has multiple load control modes and is adaptable to different industries.
Just as the picture as follow shows you, it can be applied to various occasions, such as, outdoor environment monitoring system, automatic control system for agriculture and garden, solar power system, street lighting system, etc.
All in all, if you need one kind of practicable and high quality regulator charge controller, it is worthy for your buying. Just have a try!
