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.
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 chargedSolid Red: Error-Reversed polarity
High Efficiency Solar Cell
Made of high efficiency, 30% more than competitors, works great in sunlight. The surface was covered by tempered solar glass, protecting the solar cells from snow, hail, dust, etc.
IP 65 Wateproof
IP 65 waterproof design, withstand rain and snow, no worry to mount it outside, totally free maintenance.
【 UltraSmart MPPT Technology 】This 12v solar panel battery charger is crafted with SUNER POWER’s unique UltraSmart MPPT technology, so all of its core parts, including its mppt charge controller and solar panel are built using premium and durable materials. The innovative MPPT-Charge-Controller-Technology allows to deliver high tracking efficiency of up to 99% and peak conversion efficiency of 98%, improve approximately 20%-30% utilization rate than other competitors.
【Improved 3-stages Charging】The improved 3-Stages charging algorithm (Bulk, Absorption, Float) allows to charge 12-volt battery more effectively, ensures battery is safely recharged and increases battery life and performance. The charging will be cut off when battery is fully charged, and automatically resumed when battery is not full, totally free maintenace.
【 Full Safety Protections 】Built-in multiple protections including over-charge, over-discharge, over-voltage, over-current, over-load, short circuit, reverse polarity, and over-temperature, waterproof and spark-proof, the battery is fully protected.
【 Wide Compatibility】It’s not just a solar battery trickle charger, it’s an advanced solar battery charger maintainer. A fully-automatic, worry-free smart solar battery charger for 12-volt sealed lead-acid car, automotive, marine, RV, powersport, boat, dump trailer, motorcycle, trolling motor, tractor, ATV and deep-cycle batteries, including flooded, gel, AGM, SLA and maintenance-free, plus lifepo4 lithium batteries.
【 Superior Quality and Material】Made of premium Grade A+ solar cells with efficiency up to 21%-30%, tempered solar glass and durable corrosion-resistant frame, withstand extreme weather conditions like UV, anti-rusting, and erosion, hail, and sandstorm, up to 2400Pa wind pressure and 5400Pa snow load.

I recommend this product.
This is working good on my dump trailer to keep the battery charged. Easy to install and works like it should.
Amazon Customer –
Good for moving around frequently & works well.
Arrived quickly, packaged well. Works great. I rotate it around to a couple different vehicles & trailers I don’t move frequently & it keeps the batteries up. Probably should get a couple to not worry about switching them around but this product is easy to move around.

I have had this for over two years
I love this charger. High quality and it works great over two years later. It’s easy to use and I can see it lasting a lot longer.

Great solar, bad hardware. Good product.
Does the product work! YES IT’S a Great addition to keep a trailer batterie alive.(edit)…. the provided hardware literally sheered after a few months and then panel fell off, damaged the glass. Customer support reached out to get my situation handled. That part was quite amazing. Anyways. I bought another of the same solor panel, These work good.

It’s a top notch battery tender even in indirect sunlight.
I purchased this tender for my pickup truck battery. Since I don’t drive it frequently and it often sits under a carport for extended periods, I had to replace batteries repeatedly due to disuse. Determined to find a solution, I decided to try a tender. I connected it directly to the battery, but I was perplexed when the cable designed to extend it all the way to the battery registered reverse polarity. Having read about this issue before, I added an inline converter. After making this adjustment, the tender began flashing red, but after a few hours, it displayed the green indicator of full charge.Six months have passed since I installed this tender, and I am thoroughly impressed with its performance. I place it on the dash, where it receives about 10 hours of indirect sunlight daily. This exposure ensures that my heavy-duty truck battery remains fully charged. Even during several cold spells and a three-week hiatus from starting the truck, I discovered a fully charged battery ready to go. In my opinion, it is an investment worth every penny.

Genius product
what a genius product! I love using solar whenever possible. Streamlined and easy to figure out. We will use it to keep our batteries charged on our travel trailer.

Doesn’t work unless bright sunshine
Absolutely useless.Only works in bright direct sunlight, and light is always flashing so you don’t know it’s working. LeftMy car for a week and it wasn’t very sunny and it drained the car battery. Waste of money

Works great – like it should… I’d buy again…

Purchased this solar power trickle charger for my vw beach buggy which occasionally ran out of battery power over winter. Since using this the battery has stayed fully charged with no issues. I did buy a charging socket to allow me to easily unplug the cable whilst moving the buggy out of the garage for some fresh air. There are several ways to connect up to your battery, you just need to decide what’s best for you. Great product that works well.

This is a very well made product, which worked well for 3 days and then it was stolen. What a shame because I really liked it. It was hooked up to my 12V RV and the led indicator showed that the battery was fully charged. It was in the sun leaning against the tongue of the trailer. Went out one morning and it was gone. No way of locking it up.

Purchased to keep vehicle 12v battery charged and works very well in direct and in-direct sunlight, has in built MPPT. Mounted to vehicle roof using strong coated magnets for ease of removal.

It’s solid, waterproof, uses standard SAE connectors, and should produce around 1A of current which will easily maintain most inactive 12V batteries. Support is excellent, and quick to respond to questions or issues. I actually bought 2 of these kits to maintain multiple vehicle batteries, or anything else 12VDC, and so far so good. Recommended.
