Battery naturally lose its power over time, if allowed to go flat, may never regain its power power.A 12V battery that is not correctly maintained will suffer from sulphation. The sulphation is the main cause of battery failure, this is the reason why the battery easily go dead when is left standing for long time.
Sun Energise 5W solar battery charger pro was designed to charge battery and maintain the 12v battery by converting sunshine into usable 12v current , keep it topped off at a stable level. The solar charger was built-in advance MPPT(Maximum Power Point Tracking) chip and improved three stages charging algorithm, to regulate whole charging and protect battery. Come with 3 optional SAE cable adapters, work great with car, automotive, truck, SUV, RV, boat, trailer, marine, motorcycle, etc any application where a 12V battery is used, sure to be a great fit to your needs.
Converting sunshine into DC current and trickle charge battery, keep it topped off at stable level.
The 5w was innovatively built-in mppt charge controller and three-stage charging algorithm, we do it for safety purposes. The mppt controller converts the sunshine into DC current, intelligent charge battery, limits the voltage to avoid over-charging. The improved three stage algorithm maintains the battery as a proper voltage level for extended battery life.
MPPT Charge Controller
Built-in intelligent MPPT charge controller, generates at least 10%-20% more power than competitors.
Protect battery from over charge, discharge, short circuit, over current and reversed polarity.
The improved three stages charging algorithm helpS to regulate the whole charging, better charge and maintain battery.
IP65 Waterproof design, no worry to use outside, totally free maintenance in all seasons.
The LED indicator help to visually monitor the working status and understand battery condition: Blink Green-solar output is normal; Blink Red-working to charge battery; Solid Green-battery is full; Solid Red-Errors lik short circuit, reversed polarity.
Come with quick SAE connection and 3 optional cable adapters for ring terminals, alligator clips, and cigarette lighter, the solar trickle charger is sure to be a great fit no matter what your application needs
The high light transmittance solar glass allows the solar cells absorb more sunshine and increase 2%-3% power output. And increase the ability to stand water and snow load in outdoor, totally free maintenance.
The solar charger was made of amorphous solar cells, light sensitive, wroks better than poly and mono crystalline solar cells in dimable weather conditions.
Widely used for car, marine, trucks, trailer, motorcycle, RV, SUV, boats etc,or any application where 12v battery is used.

Don't Just Take Our Word For It
"EaseUS Partition Master Free Edition has been a go-to recommendation for a powerful yet easy-to-use disk management utility that just happens to be free."
"EaseUS Data Recovery Wizard is the best we've seen. It's far from perfect, partly because today's advanced disk technology makes data-recovery more difficult than it was with the simpler technology of the past, but it's fast and efficient, and it recovers files that we couldn't get back when using its chief rival."
"EASEUS Data Recovery Wizard Free mixes up a user-friendly approach with a handy suite of features in order to help you recover files that you have accidentally deleted from your computer."
"A perfect balance of automatic protection and manual control.EaseUS Todo Backup Free has lots of bases covered: backing up individual files and folders, whole drives or partitions, or creating a full system backup. There's also a 'smart' option that automatically backs up files in commonly used locations, and you have the option of using cloud storage."
"I love that the changes you make with EaseUS Partition Master Free aren't immediately applied to the disks. It makes it way easier to play out what will happen after you've made all the changes."
