Waterproof 12W 12V Solar Battery Charger

【Portable & Charge Anywhere】- Lightweight and portable solar charger. Transfer sunshine into electricity, charge and maintain different 12V batteries such as flooded, gel, AGM, SLA, VRLA, lithium-ion battery of RV, car, boat, marine, automotive, snowmobiles, trailer, camper, etc. in all seasons.

【Intelligent Charge & Maintain】- Fully protect the battery! Built-in intelligent MPPT controller, generates at least 20%-30% more power than the other controller. Smart 3-stages charging algorithm effectively prevents the battery from over-charge, over-voltage, discharge, short circuit, etc.

【Upgraded Visual Monitor】- The colorful LED indicator helps to visually monitor the working status of the solar panel and battery. Charging will be cut off when a battery is fully charged and resumed automatically when the battery has a discharge, totally free maintenance. No need to worry battery going flat anymore!

【Waterproof & Hign quality Materials】- Use 30% high conversion efficiency crystalline silicon material + high-strength solar energy glass which has 95% strong light transmittance and waterproof performance, can withstand harsh weather conditions.

【Free Maintenance】- Tempered glass and strong ABS frame, well built for years. Come with 3-piece SAE cable kits, plug and play, easy to use. No electricity cost, free maintenance for outdoor usage.

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 the sun light, as long as there is sufficient sunlight available, the charger will generate an electrical current to trickle charge battery. The charger is built in the most super intelligent MPPT(Maximum Power Power Tracking) chip to intelligently charge and fully protect battery. The MPPT technology helps to generates at least 20%-30% more power than traditional PWM. And the LED indicator helps better understand the charging statue in all days.

Visual LED Indicator:

The led indicator allow to clearly monitor working status:

Blink Green: Sunshine is effective (Not Acitve yet)
Blink Red: Working to charge battery (Activated)
Solid Green: Battery is fully charged
Solid Red: Error-Reversed polarity
