Description
- 💦【Function】Suitable for keeping vehicles/boat battery charged during the weeks unused. No need to disconnect the battery or have someone start the vehicle periodically. The indicator light on the back can observe the charging state. And it’s waterproof, you can safely use it outdoors(After experimental test).
- 👷【Protection】The 10w monocrystalline solar panel uses trickle charging to charge the battery without causing overcharging. Built-in blocking diode prevents reverse charging without extra maintenance at night. Works even on cloudy days. As frosted surface, the panel doesn’t need film protection anymore.
- 🔎【Version Upgrade】Because of PCB upgrade and the addition function of reverse and overcharge protections, it may not be possible to test the open-circuit voltage. Don’t worry, the panel is still working normally.
- 🚗【Easy to Install】Equipped with SAE cable, just plug the cigarette lighter into the port or connect the battery terminal posts with the alligator clip, and the connection can be completed within 3 minutes! Suitable for car, truck, boat, lawn mower, motorcycles, trailer, dump trailer, tractor, RV, van, camper, ATV, utility vehicle Battery etc.

puissance juste suffisante pour qu’une batterie de voiture garde sa charge , mais c’est pas la faute du produit mais du soleil. plus facile à brancher si l’allume cigare de votre voiture est alimenté contact coupé.( ça doit exister dans certaines voitures).

I’ve been using this about 1-2 times per month when my vehicle is parked while I’ve had to fly out of town.
After a week (+/- a day or two) I’ll come back to a pre-start voltage reading of 11.8-11.9-12.0V.
I’ve not used the battery maintainer 2-3 times just to see if there’s a difference, and I’ll get the same pre-start voltage readings (11.8-11.9-12.0V) that I would if it had been hooked up.
I’ve tried different locations where the panel should get unobstructed sunlight, even putting it in the sunroof so it will get full exposure for the duration of the day.
The fact that I’m consistently getting low pre-start voltage readings regardless whether I use the battery maintainer makes me think it’s just not working.
Unfortunately there’s no way to hook up a multimeter to this thing and see what kind of output (if any) it’s producing.
I’ll more than likely end up getting another different brand solar panel battery maintainer to try as a comparison to this one. I’m being optimistic right now in giving this 3-stars, but if it turns out another solar battery maintainer gives me higher pre-start voltage readings then this review will get edited to 1-star.

The first order arrived used and missing parts. Amazon processed the replacement and provided for it’s return.
Weeks later, during which the item was still being sold but for a dollar more, they eventually sent out the replacement. It arrived with clear packing tape added to it over the security sticker that seals the box.
Seemed to be new, with all its parts except that the only version of the instructions was in German or Dutch which I cannot read. So I MATCHED EVERYTHING TO THE AMAZON PAGE but missed the step about removing a clear covering “AS THERE WAS NO COVERING OF ANY KIND”, so I reached out to the seller through amazon and received NO RESPONSE FROM THEM.
So I figured as it wasn’t rocket science, I could get it set up, and the next day I tried to suss out the seemingly simple set up, but I missed the GERMAN/DUTCH NOTES about not leaving it installed when starting or running the engine “AS I WAS RUNNING THE A/C IN THE 107 DEGREE HEAT” performing this simple set up.
– Reference from .pdf – “Before starting the motor, remove the cigarette lighter plug from the socket and do not use this charging method while driving. The vehicle’s motor may produce an electrical surge that could damage the solar panel.” -.
“NOW, NOT KNOWING IF I HAD CAUSED DAMAGE TO IT OR TO MY ELECTRICAL CIRCUIT”, I contacted the seller AGAIN, relaying what had occurred during the installation, and that I had eventually found a .pdf manual on the Amazon page, but that I was uncertain if it was the most up to date version as it mentions the “NON-EXISTENT COVERING REMOVAL , but does mentioned to not start the car while the solar panel was installed – so I asked what would be the result from having the car running while installed, would there be any damage to the circuitry – AND RECEIVED NO RESPONSE FROM THEM.
STUPIDLY, even knowing better at this point, I left it connected to my new battery to see if would maintain the voltage I measured at the battery, even with IT’S OWN VERY BRIGHT LED ON THE PLUG AND THE DIMMER ONE ON THE BACK OF THE PANEL ADDING TO THE PARASITIC DRAIN ON THE BATTERY……NOPE! My 2 month old, bought it brand new off the self after waiting two weeks for stock to arrive battery was suddenly unable to start the engine.
I only wanted this to produce enough of a charge to keep the battery topped off and prevent the batteries lead sulfate from crystallizing, as it sits for long periods of time.
I did look into it as much as I could, to try and figure out why this brand had some of the highest ratings among the different solar panels. Instead I discovered that they seemingly want to bypass Amazon’s being aware of any problems, and the customers having Amazons protections, by providing this on a contact page:
“If you do not receive our email reply on Amazon for more than 24 hours, some words may be blocked. Because we will reply to Amazon’s email within 24 hours, if this problem occurs, please contact us through the email below.
Email ①: [email protected]
Email ②: [email protected]”
I’m not sure why, legitimately, they would want to block any “WORDS” coming from Amazon and prefer to bypass the copies of communication between seller and customer that Amazon reviews, but I do have a few guesses…

Min beställning var ((ECO-WORTHY 12 volt 10 watt bärbar kraftpanel laddare backup för bil båt med krokodilklämma adapter))….men jag fick ((ECO-WORTHY 10W 12V bärbar liten solpanel solenergiladdare för bilketer förölängägs )).
Eftersom jag tidigare köpte den sistnämnda för ett tag sedan och med mindre hår än den jag betalade för den aktuella beställningen.

I got one of these solar panels few months ago. It seem to be working great and I got recently two more.
Too many vehicles not driven enough?

I hooked this unit up to my Polaris Ranger, which had a kind of low battery from sitting to long. It turned over and started but sounded weak. I hooked up the unit, the next day I went to start it, completely dead, nothing. I put my multimeter on the alligator clips with the solar panel in the sun, checked voltage in DC mode, it read 18.3 volts. That is a lot. Tested on AC mode, 3.4 volts. I am guessing my battery terminals are carroded or the battery just happened to give out. I put the battery on a real charger, did not show any problems as far as sulfated or cell problems. I am puzzled.
EDIT- I placed the solar charger onto the same battery, left the battery uninstalled outdoors with the solar charger hooked up, after charging the battery on a regular charger to full charge. I tested the voltage over several days, morning and evening. The volt meter showed 13.1 during the day, 12.9 at dark. This trickle charger works fine. I am going to order 2 more, one for my RV and another for a generator with a battery in a remote location. The price has gone up on me as the sale is over, my bad. Good unit!

This works great. Love the flexible design

It will not charge a dead battery, it is not intended to. It simply keeps a good battery charged on vehicles that sit without use for a long time.
The product itself is great, I bought 3 of them.
What happened is, the first 2 I bought were delivered but at 2 different prices 🤔so I called Amazon and was told they can’t help me. So I ordered 2 more at a discount for buying 2 and I returned the higher priced 1 still new in the box. Did not seem to me to be the most efficient way to handle it but, that is humans!
The 2nd problem was that the delivery person left the package OUTSIDE instead of INSIDE the safety of a closed in screen porch 🙄. I live in a ground floor house with no steps but yet the package was left outside in plain view from the street and in any possible weather. They simply ignored my delivery instructions and all forms of common sense and respect. If I delivered, I would put things inside a porch whenever possible just for common sense and respect! I can’t understand this way of thinking, can you 🤔???

Bought this for trickle charging my Ford F250 battery while parked for a year of deployment. Have used it since to charge motorcycle batteries (street and dual-sport) when away from outlets. Easily mounts to inside of windshield or to body parts with suction cups. Provides sufficient power to charge 12v batteries. I have used this for 2 years now; no problems.

Works perfect in for my 2005 silverado. Just plug in to cigarette accessory socket and it holds a charge
