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.

Reliable and durable.
Used on a sailboat to maintain charge in battery used for navigation lights. Kept that battery fully charged all summer. Doesn’t take up much space and it’s not as fragile as other chargers.

Simple and effective.
Great product. Works well to maintain my trolling motor battery while using it. Needs lots of sun, not a problem here in California.

worked better than expected,,,,but…..
So, I have the 12W/12V one. First, it comes with plenty of connection styles. So that is a plus. I have a battery on my utility trailer which runs the electric jack. I use this so I do not have to hook it to truck all the time. Love it. It charged the battery from dead dead and it now keeps it sustained. I did not permanently mount it so I can take it down easilyNow the bad. The battery has the SAE connector for ease of connections. (to avoid reading the rest I will put a note here and tell you the connectors on the solar panel wires are reversed.. read on if you need an explanation)… As does this solar charger. So, there is no way to hook it up wrong. And the battery is hooked up correctly (red to positive/black to ground) . Having said that I hooked the solar panel (supplied with the panel) SAE connector and the LED light on the solar panel LED blinked weird. So I looked up the code on the Solar panel instructions and it says it was reverse polarity. Again, I can not hook it up wrong. So, I had to use the alligator clips (and reverse the clips on battery) to get it to charge. Works great now but I cannot use the SAE connectors as it is backwards. Weird. Minor inconvenience but it should be mentioned.

Great Customer Service
I purchased this solar charger 15 months ago. It worked flawlessly until recently where is stopped functioning. I sent a note to Suner Power where they were very responsive. Frank at Suner Power is currently working on getting me a replacement unit. The warranty period is 12 months, but they are doing there best for a replacement. I would purchase again based on there resposiveness in helping me. Update Suner Power shipped me a new unit. Great Company to deal with. Very responsive.

well worth it!
i maintain a lot of vehicles for myself and family. many sit for months on end like atvs, motorcycles, heavy equipment, trailers with dump and winches, and extra or project vehicles.it’s way too many batteries to let sit and die and then have to replace year after year.I’ve bought around 15 of these chargers over the last 5 years and they all still work great! keeping the batteries in great shape and vehicles ready to work or play! I’ve built a few mounts to sheds or storage units and ran extensions to reach anywhere i need to go. it’s nice to plug them in after use and forget about it.

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.
