  • so far so good! works GREAT even in cloudy weather!
Size: 10W
immediately powered up and kicked out 15-16 volts unloaded, in rainy/cloudy weather no less. Connected it to the battery and the trickle charge was enough to power the car back up to the threshold for the key fob to work again after less than an hour. Battery obviously has issues and we plan to get a new one tomorrow, and plan to keep this solar trickle charger hooked up help offset some minor parasitic drain. I see some reviews expecting this to charge a dead battery....but that's never going to happen with a panel this small, and it clearly tells you that before you buy it. It's only meant to keep a healthy battery topped up, not bring and unhealthy one back from the grave. Most of the neg reviews are just people who didn't read. ... show more

  • Exactly as advertised
Size: 10W
I recently purchased the 10W Solar Battery Charger, and I am extremely satisfied with its performance. The charger is suitable for keeping vehicles/boat batteries charged during weeks of disuse, without the need to disconnect the battery or have someone start the vehicle periodically. The indicator light on the back allows me to observe the charging state, and it’s waterproof, making it safe to use outdoors. The 10W monocrystalline solar panel uses trickle charging to charge the battery without causing overcharging, and the built-in blocking diode prevents reverse charging without extra maintenance at night, ensuring protection against damage. The panel works even on cloudy days, making it a reliable source of power. The upgraded PCB and addition function of reverse and overcharge protections ensure that the panel is still working normally, even if it's not possible to test the open-circuit voltage. The charger is easy to install, equipped with an SAE cable that can be plugged into the cigarette lighter port or connected to the battery terminal posts with the alligator clip. The connection can be completed within 3 minutes, making it suitable for use in cars, trucks, boats, lawn mowers, motorcycles, trailers, dump trailers, tractors, RVs, vans, campers, ATVs, utility vehicles, and more. Overall, I highly recommend the 10W Solar Battery Charger to anyone looking for a reliable, easy-to-use, and effective solution to charge their battery and keep their vehicle or boat running smoothly. ... show more

  • Seems working with some suggestions to manufacture
Size: 10W
It seems working, left for two weeks and came back battery could still started without problem. However, it is hard to tell if it is charging or not. The green LED indicates sun light also charging with no distinguish. Why can't they make green LED blink to indicate charging, solid green to just indicate sun light detected? Also the LED is located in a hard to see place, why don't they put LED facing outside, so that users can see it through windshield. ... show more

  • Works great for trickle charge.
Size: 10W
This works great to trickle charge my generator battery. It seems to die due to lack of operation. However this has kept the battery charged so that I can use my remote start effectively. Great buy!

  • False advertising (???)
Size: 10W
UPDATE - 5/10/23 - I have had this connected to the less-than-one-year-old 800CCA AGM battery in my convertible for two months. It faces pretty much due West and gets plenty of afternoon / evening sun yet it will NOT charge the battery above 11.4V. There's no way to know if the panel is connected and providing a charge due to no status light, and you can't actually measure the output voltage or current without it having a charging load attached (which defeats the purpose of being able to tell if the panel is even working as you'll get voltage readings off of the battery). I've since been able to repair my Battery Tender 5W panel (discontinued model) and re-install it to bring the battery charge level up on the car. Within the listing, in multiple places (including product photos), it claims that this charger is waterproof. The box, however, literally says "Keep Dry" and shows a graphic of an umbrella protecting it from water (see photo). Also in the listing, and in the product instruction sheet in the box, it says that you have to remove the "protective film" before using it. There is not film installed on the charger anywhere. The device is a cheap piece of fiberglass with the solar cells mounted to it. The charge controller is on the back side with nothing incorporated into the design to help keep water, snow, etc. away from it. I'm not even going to waste my time trying to install it because it isn't worth the effort. I will buy a unit from BatteryTender brand as I know they are quality built and are actually weatherproof. ... show more

  • Works even on cloudy days, keeps my battery from draining
Size: 10W
I tested this solar charger on a cloudy day using a multimeter and it was producing about 17.8 volts, so it definitely generates power even without direct sunlight. I installed it yesterday, and today I noticed my car battery has been staying very consistent around 12.2–12.3 volts. I already know my battery isn’t in the best condition anymore, but the charger is clearly helping maintain it. I also have a Viper SmartStart system, which constantly drains a little power from the battery. Before installing the solar charger, my battery would usually drop to around 11.8 volts overnight. Since installing this panel, the voltage has stayed steady at 12.2V since about 6 AM, which honestly surprised me. So far it’s doing exactly what a trickle charger/maintainer should do, keeping the battery from draining while the car sits. For a small 10W panel, I’m impressed. I would keep checking and see if anything change. ... show more

  • cigarette lighter no, direct to battery yes
Size: 10W
I bought this product to charge my truck battery as I have a drain that empties the battery if I park it for a few days. I figured that if I use the solar charger, my truck will get an extra charge to the battery, which will do me good as I drive short distances and the truck is parked most of the day. I used this product religiously, every time I turned off the truck I plugged the charger into the cigarette lighter. I followed the instructions, which said to use the lighter port that illuminated the light on the charger. I started measuring the battery voltage at night after I got home, and again the next morning and I kept a log. Anyway I noticed that this charger made no difference to my battery at all. I used it a different car and had the same result. So it didn't work at all through the cigarette lighter. I hooked the panel directly to the battery one day and measured the voltage and it worked well. It was charging the battery. My advice would be to wire this panel to the batter directly, maybe with a switch to turn it off at night and when the car is running. But, not to bother using it through the cigarette lighter. ... show more
