3 Best Solar Car Battery Chargers

Short on Time? Here’s The Article Summary

The article highlights the benefits and functionality of solar car battery chargers. It explains that these chargers use solar panels to convert sunlight into electricity, which is then used to charge a vehicle's battery. Solar chargers work gradually, reducing the risk of overcharging and extending the battery's lifespan.

The advantages of solar chargers include their environmental friendliness and the ability to generate electricity remotely, ideal for off-grid locations. The article also emphasizes the convenience and portability of these chargers, making them popular among RV enthusiasts and campers.

However, it notes that solar car chargers are not designed to revive dead batteries but rather to maintain them by providing a trickle charge. For larger solar power needs, the article recommends portable solar generators like the Lion Energy Safari LT 500, ROCKPALS 500, and Rich Solar X1500, which offer varying capacities and features to suit different needs.


3 Best Solar Car Battery Chargers

A solar car battery charger offers you the convenience of mobile power and all the benefits that come with using clean, renewable solar electricity.

How Do Solar Battery Chargers Work?

Solar battery chargers are actually fairly straightforward devices. Essentially, they use solar panels to absorb sunlight and transform that energy into useable electricity. The electricity is converted into DC current, which can then be used to charge your vehicle’s battery.

While they undoubtedly work faster and more efficiently when they are exposed to direct sunlight, they can still work in low-light conditions. While some chargers are designed specifically for car batteries and connect directly to them with clamps, others can be used to feed power to the vehicle through the 9V power socket/cigarette lighter plug.

What are the Advantages of Using a Solar Battery Charger?

Where standard car chargers are typically used to fully charge a completely dead battery, solar chargers provide electrical current to the battery in a more gradual way, which means they are far less likely to cause overcharging issues and permanently damage your battery.

Of course, the other major difference is that they use solar electricity. While using clean energy is beneficial from an environmental standpoint, it is also beneficial because it can be accessed remotely. Basically, you have the ability to generate usable electricity, without having to be connected to a traditional electricity grid. If you drive your vehicle to remote, off-grid locations, this ability to turn sunlight into useable electricity is incredibly beneficial and offers a whole new level of freedom to your adventures.

They are also incredibly easy to use and can extend the lifespan of your vehicle’s battery. Best of all, most are designed to be highly portable, so you can take them with you no matter where you plan on driving. This partially explains why they are so popular with RV enthusiasts and those that like to drive to remote camping locations. Find complete RV solar panel kits

Should You Use a Solar Car Charger to Revive a Dead Car Battery?

Typically, solar car chargers are not designed for this purpose. Instead, solar-powered car battery chargers are designed to function as trickle chargers, which means they charge at a rate that is equal to the self-discharge rate. Essentially, they keep the battery topped up, so it will not completely fade out.

For each of the following car battery charging options you'll need to purchase a $20-$30 110V to 12V battery charger that you will then use to plug into the portable solar generator in order to draw the power out and into your car battery.
