Product Description

As we all know, batteries naturally drain power and if allowed to go flat, may never regain their full power. This product is a solar powered battery maintainer and charger for 12V batteries and helps manage battery drain in all season. The solar charger converts light energy from the sun into 12 volt DC electricity which is then transported to the rechargeable batteries through lead wire and connector of choice, replace the self-discharge of a battery in storage, so that the battery wouldn't "go dead". It can be used for cars, 4WD’s, trucks, motorcycle, marine, boats, farm equipment or any application where a 12V battery is used.

The high efficient solar panel allows to absorb a wider spectrum of sunlight, as long as there is sufficient sunlight available, the charger will generate an electrical current to trickle charge the battery. The charger is built in the most super-intelligent MPPT(Maximum Power Power Tracking) chip to intelligently charge and fully protect the battery. The MPPT technology helps to generate at least 20%-30% more power than traditional PWM. And the LED indicator helps better understand the charging status on all days.
