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 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.

Suner Power 12W 12V Solar Battery charger Pro – 2 month review
I have a latemodel 5th gen 4Runner, purchased new. It isn’t driven very often: after two years, it has amassed a whopping 3000 miles 🙂 Great vehicle for me, but unfortunately, the telematics on this vehicle (SOS button, auto dial in the event of a serious crash, etc.) pre-dispose it to parasitic battery drain. This is a common problem for these vehicles if driven infrequently, a Toyota problem; my 15 yr old Ford P/U has similar telematic features but cranks without fail, even though it gets the same intermittent use.After replacing the battery twice on a virtually new car, I tried this solar charger. I’ve had it going on three months now. I leave it connected to the terminals and disconnect it quickly, using the quick disconnect lead included by the manufacturer. It stores easily in the seat pocket behind the driver seat. Compact, weatherproof and durable with nothing to switch on/off, it comes with an led indicator to show what it’s doing once connected.Blinking green shows ‘ready’ and blinking red indicates current is flowing to the battery. Circuitry prevents over charging. As simple as that to use.I monitor the charging performance and battery state using an Ancel BM300 Bluetooth Battery Monitor ($35 on Amazon) which sends info to my cell phone at designated intervals or on demand. The battery is always topped off and ready to go. Problem solved.The Amazon listing shows suction cups that permit sticking the panel to a suitable surface while in use. I didn’t receive suction cups with my charger (an omission, I believe) but that’s not a problem. I affixed four coin-sized magnets to the reverse side which secures it to the hood or roof when in my driveway. If using it in a less secure location, I would keep it inside the vehicle, flat on the dash. The harness has a generous length, making routing to different spots simple.Would I purchase this again? Yes. 5 stars for simplicity, performance and ease of use.

Great setup
I set it up on my gooseneck equipment trailer and it works great. Purchased the trailer in 2018 and it still has the original battery. Good value for a fine maintainer.

Solar Battery Maintainer
I bought this for my deep cycle battery on my camper. I spent 9 days camping in September and it worked great. I wasnât hooked up to power but I did have a generator. I didnât need the generator as much this year. Most of the days had ample sunshine but I was in a valley between two mountains. Easy to hook up as well.

It does work, but not great
The product does charge a battery, but only to about 80% after several days. I bought three of these for a fuel trailer and dump trailer. The dump trailer hasn’t been used in a week and the battery is still not fully charged. It’s better than having a dead battery, but it’s not going to have a 100% charge.Also, the suction cups are mediocre. I would prefer to see a magnetic option.

Well built, powerful, built-in controller with a useful status LED. Great company support.
I have two of these 12 watt 12 volt solar charger / maintainers. One I’ve had for over a year and used for a pontoon boat battery so it only is used during the 5-6 month boating season in Michigan. The second I just bought in July for a PWC battery. I love how well built they are. The status LED can tell you if it’s charging, open circuited, incorrect polarity, shorted or fully charged (the LED is on the front of the unit so it’s readily readable). It requires minimal exposure to outdoor lighting to operate, even charging a small amount in fully overcast conditions. I’ve used my volt meter in amp mode to measure current output under various lighting conditions and it works at least as well as advertised, if not better.The biggest reason I felt compelled to write this review is that about two weeks after receiving my second panel (bought in July 2023), the unit quit working reliably. It would work for awhile then quit (LED went blank even in direct sunlight) then mysteriously it would start working again . I contacted the company and they asked me to send a video showing the LED not working while the panel was in direct sunlight. Once they received and confirmed, they sent a new unit to me directly from Amazon without me having to send the old unit back. In all it took about four days from contacting the company to receiving the new panel. This company deserves our business from both a product quality and company support perspective. The new panel I received is working very well so far and the panel I’ve owned for a year has worked flawlessly since purchasing in July of 2022.

Works great
I love the convenience, I use it for my motorcycle, keeps the battery at a full charge

Works great, waterproof claim is true.
I’m currently using this to keep the VW bug charged due to a parasitic draw. It works great. The 12v connection did not work for some reason, so I’m directly connecting to the battery via the battery clips.

Delivered w/in 24 hours ready for plug-in and play
This was a replacement for a cheaper charger that melted in the sun. I use it to keep my car battery from discharging due to idle current draw from all the electronics. Seems to be working just fine. It is a little larger than my previous charger but nonetheless fits well on the dashboard top. The red/green indicator lights are confusing until you read the on-line Q&A’s. Flashing red apparently means it is charging your battery. Steady red means your battery voltage is too low (well below 12V). Flashing green means you’ve got enough sunlight but your battery does not need charging.

We bought this for our boat batteries. Works as it should, small compact unit fits where we wanted to put it.

Using to keep our generator battery charged. Working well as needing to run the generator at the moment.

Was skeptical at first due to not sure of true MPPT charger, but turns out to be true mppt charger. The only thing I wish it came with is cable adapter to OBD2 connector. This is important as most cars, only the obd2 connector is operational even the ignition key is off.Only four stars as I have to make my own obd2 cable to be able to charge the car internally, even with ignition power is off.

Even though the flashing green lights indicates itâs charging I didnât verify output when installed. I went to start my boat the the battery was dead. After putting a meter on it was reading -5 to + 6 resulting in draining my battery. Unfortunately I canât return.
