About this item

Charge Visualization：The indicator lights can help you understand the charging status
Intelligent Protection：Built-in blocking diodes can prevent reverse charging and can be safely used for charging and maintaining 12 V batteries
Higher Conversion Rate：The regular convex points of surface distribution are conducive to the secondary propagation of light, absorb the radiant heat of solar energy to a greater extent, and greatly improve the photoelectric conversion efficiency
Widely Used:The included three -pieces SAE cable kit is plug-and-play,it can be used for cars and 12 V batteries. Comes with carabiner and suction cup to meet your different installation needs. Suitable for automobiles, RVs, motorcycles, ships,snowmobile，etc
More Durable:The PET material can be waterproof and dustproof. A layer of epoxy board is added as a bottom plate, which is more sturdy (the broken panel will cause the charging efficiency to decrease). You can contact us at any time if you have any questions

    5.0 out of 5 stars Stopped working after 2 months (Or so I thought) [UPDATED REVIEW]

    Original Review:
    At first I really liked the panel, I have a Bluetooth adapter that reads battery voltage and I could see the charge go up if I sat there for a few seconds. I was checking voltage regularly (every 2 or 3 days) to make sure it was keeping my battery at the properly charged, which it was. So when I finally decided to trust this and not be checking it so often, it stops working. Now I have a dead battery and will have to pay to have it replaced. Not happy.

    Updated Review:
    Let me start by saying that the reason my battery drained was not this solar panel's fault. Turns out the Hands-Free Link module in my car had gone bad and was draining the battery even when the car was off. Once that was found to be the issue, thanks to a friend that has the same car I do and coincidentally started having the same battery drain issue too, he told me what was causing and how to get to it to unplug it to test if my HFL module was draining the battery. After the HFL module was unplugged I then though to take this solar panel out from storage and check, I had not used it since I labeled it as "bad" but never got to throw it away since I thought it did put out some power just not enough for my car. Well now I can say that my car can sit indefinitely, the battery will not die anymore and has not gone bellow 12.3 volts even after 3 weeks of the car not being used.

    4.0 out of 5 stars Doesn't like the elements
    Reviewed in the United States on September 7, 2024
    Used as a battery tender for my car in storage. Works great if you leave the solar panel on the dash but it doesn't like being in the elements if you put it on the outside of the vehicle. Barely had it a year and it no longer charges. Completely dead. It worked great when it did work though.

    5.0 out of 5 stars It's in my moon roof
    Reviewed in the United States on October 3, 2024
    For years, my Toyota Sienna van has been the ugly step-child of our automotive family. We're retired, so it sits outside and waits for the rare occasion when we both need a car at the same time or we need to transport something large and/or dirty that we don't want to put in our "nice" car. This means that sometimes it's a couple months before it gets on the road to charge up the battery. Due to this, we've gone through three brand new batteries in the past 7 years.

    I had a trickle charger on there before, but it was only 7 watts and really not up to the challenge. After spending yet another $200 on a new battery recently, I decided to upgrade to this 30W charger. It's only been a week, but so far, it's doing well.

    My wife wasn't thrilled about this massive solar charger blocking so much of the windshield, so I came up with a rather ingenious solution (if I do say so myself). We never use the moon roof, so I put it up there. It's working great.

    BTW... if you're having battery problems, it might behoove you to buy a battery monitor. I bought one on Amazon that has bluetooth. The bluetooth range isn't anywhere near what they advertise, but if I can get within 10' of the car, it downloads a minute-by-minute data dump of what the battery has been doing for the past 30 days, making it easy to catch battery issues before it's too late.

    Perfect go to charger for my golf cart, four wheeler or side by side batteries. Super easy to use and monitor progress. Fast charge and good value! Lightweight too!

    5.0 out of 5 stars works perfectly
    Reviewed in the United States on November 3, 2024
    Picked up to keep the battery charged in a second vehicle that is rarely driven. Battery would be dead in a week or so. Plugged into power port, and set the panel on the dash, and after 3weeks, the engine turned over and started easily. Measured it at 18v at 1.5amps.
    Would buy again. Panel is super thin, but tough and slightly flexible. Really pleased with the performance and quality.

    3.0 out of 5 stars Bad Fuse in cigarette plug-in.
    Reviewed in the United States on November 21, 2024
    Arrived on time. Eager to hook it up to my C5 corvette, I was disappointed to see there was no "connection". My trusty voltmeter detected no continuity in the + lead. Visual inspection did not detect the defective fuse. Replaced the fuse at my expense and with the wrong size for now. Uses a 5-amp 250 volt. I only had a 10-amp 250 volt. It now is showing that it is connected and charging. Yes, I will get the proper fuse Amazon at my expense.
