ECO-WORTHY 𝐔𝐠𝐫𝐚𝐝𝐞 7.5W Solar Car Battery Charger Maintainer 12V Waterproof Solar Panel Portable Solar Trickle Charger for Car Truck Boat Lawn Mower…
[Upgraded Smart Charger Controller] The smart charger controller built into the solar panel has six protection functions: over-temperature protection, prevention of reverse discharge, short circuit prevention, prevention of reverse polarity and over-charging protection. Meanwhile the built-in blocking diode plays an important role in blocking reverse current flow.
[Real-time monitoring] The LED indicator has three display states, half lit means charging, blinking means fully charged, and off means no input or no battery connected. When fully charged, it will automatically cut off charging, effectively preventing the battery from being overcharged.
[Stronger and More Durable]After rigorous testing, the A+ grade monocrystalline silicon wafers have a conversion efficiency of up to 23% to maintain a consistent output of 7.5W. The glass fibre surface is highly resistant to the environment, with IP64 waterproofing and UV protection.
[Easy to Install and Use]The Outdoor Solar Battery Maintainer is simple to install and easy to use, just directly connect the solar panel to the battery with alligator clips. The solar panel is bendable to fit windscreens and has a strong hold on the 4 PVC suction cups it is equipped with. Also, it’s easy to carry outdoor and restore on your car. Dimension: 9.84*8.66*0.47in, 0.05lb
[Wide Application] The perfect charger/maintainer for any car, LiFePO₄, Lithium Ion, motorcycle, boat, tractor, ATV, farm equipment, and 12V batteries.
[Tips] This product comes with a cigarette lighter with the package.Please note: This cigarette lighter is not suitable for all vehicles. Cars before 2015 can be charged using a cigarette lighter. On newer cars, the cigarette lighter will not provide power until the vehicle is started. Please choose the most appropriate charging method according to your vehicle to avoid unnecessary trouble for you.

This seems to work as promised. I left it plugged into the lighter of a vehicle that didn’t move all summer. It started right up. The only thing I don’t like about this is the lighter plug has a tiny red LED that stays on all the time. I thought it was to indicate it was charging since it comes on when you plug it in. However it stays on at night with no sun light, so that is draining the battery of about 10 to 20 miliamps. It doesn’t matter much because it adds way more than that when the sun comes back up. But they could just add a simple schottky diode to prevent it from sucking juice out of the battery. The manual/specifications claim it has backflow/reverse flow prevention, that must be near the panel not in the lighter part. So it doesn’t drain your battery, but the led stays on at night.
Overall this works pretty good though. It is easy to just plug into the lighter outlet on your car and keeps the battery charged up.

Had an old lawnmower John Deere. only used it once a month or more. this solar charger keeps the battery charged now I don’t have to jump it off every time I need it.

I bought this to keep my riding lawnmower’s battery charged between uses. It is exactly what I need. Completely automatic and dead simple to use – no buttons, knobs or switches – just clip it on.
Monitoring it on a succession of sunny Northern California days, the voltage varied from 19.2-19.9v and the current ranged from an initial 0.36A to 0.22A over 5 days, supposedly being reduced by the charge controller as my battery reached full charge. These closely match the documented specs.
All in all, a fine product priced to give great bang for the buck.

This is a great-sized panel and light-weight. It is quite thin. You could carry it in your backpack. Comes with a cigarette lighter adapter and two clamps.
It charges and does the trick, but it is a bit slower on the charge than other panels I have.

There is no LED indicator light.
This little light weight panel seems well made and does work. Specs aren’t exactly accurate, though. I was able to get about 20v and .7 amps out of this panel under full sun, higher than it’s rated, which is great. Now, don’t worry, this isn’t going to over charge your 12v battery. The reason is the low amp output. I still have to thoroughly test my unit, but so far it hasn’t gone over 13v.
I also adapted it to a quick disconnect set up and have 18awg marine duplex wires running through my cars firewall to the battery so that I can keep this panel inside, as well as disconnect it to run a battery charger as necessary. I also don’t like SAE connectors that much. They’re ‘okay’, but not my favorite.
Overall seems like a good buy just to keep your batteries topped off during the day.

Battery is on a dock that raises a boat lift. Battery has always stayed charged.
