Works but also doesn’t
Update - vendor reached out regarding the faulty product. Look, nothing will ever go perfectly… we all need to understand that there will always be hiccups. It’s how you handle the next steps and they delivered. They contacted me and wanted to make it right, replaced it with a new product and I’m one happy customerI have mixed feelings about this product. When I first got it, I was excited. Product did exactly as described and kept my battery life up. I travel a lot for work so my car is often sitting at the airport lots so this was great to have when it was idle. I’m not sure if it’s because I live in Florida…. But in just 2.5 months the panel started to deteriorate. Never had it sitting outside the vehicle and it’s always been inside, but you can tell moisture started building up and the plastic design started to bubble up. I really liked the product but it did not last long at all…
Thank you for your feedback

    Got it in the mail this morning, hooked it up to test how many watts it would put out in a cloudy day. Its so well made I noticed the Instant i opened the Package, Great price I might mention for such a well made product. Had it set up and working in less than a minute, so easy to use and simple Instructions. I was putting out half the watts, around 5 of the 10 watts I will put out in full sun but Its so cloudy here today I had to test it to see what will do on a cloudy day. I have a jeep that I use for maybe 1 day a week on a short trip so it want even charge back full the amps removed just to start it up. THis thing is exactly what i needed for a long time now.

    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: amazonzyh@163.com
    Email ②: customer.service@eco-worthy.com”

    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...

    Got it two days after ordering. Green light indicating it is charging is working even on very overcast day. Hardest part was getting the suction cups into the grommets on the panel, but that is probably a good thing since they won't fall off easy. Sticks outside on front window even on a very cold day here. So simple I wish I would have done this at the start of winter.
    I had decided it was too difficult to take the batteries out of my new Winnebago View, and instead started it up once a week. I was unaware that with a modern diesel this is not advisable. After about 6 times doing this on the weekend, the check engine light came on and I believe I have a 100% full Diesel Particulate Filter.
    I will take this with on regular camping trips because of all the stuff this Mercedes does electrically it can kill the battery even in as short as one week.
    What an inexpensive quick solution to my problems!!
    Highly recommended.
