A portable solar car battery charger uses solar energy as the source of power. There are many advantages of solar power over conventional power sources like fuel because solar energy is clean. This means that it does not pollute the environment.

What’s more, solar energy is free once the installation costs have been met. To convert sun rays into useful power, one needs a solar panel. This principle is no different when it comes to solar car battery chargers.

The 10 Best Solar Car Battery Chargers

Why Solar Car Battery Charger is the Best Option

Most solar-powered chargers charge slowly which is a good thing right? Yes right. You see, when a battery charges too fast, a lot of heat is generated which reduces the shelf life of the battery. In extreme cases, rapid high voltage charging may cause the battery to explode.

As earlier mentioned, the solar chargers use the sun which is readily available, and you will not need any specialized equipment to charge your battery. This makes charging your battery very easy and convenient. The case is different with an electric charger as you would have to look for a power source to do the charging. Let’s have a look at the 10 best solar car battery chargers.

How Does Solar Car Battery Charger Work?

The portable solar car battery charger uses the sun as its source of power. Usually, the charger has a solar panel that is portable, and you can place it on the dashboard or the roof of your car. Regardless of where you place it, make sure there is enough exposure to sunlight. The solar panel converts the sun rays to DC which charges the car’s battery. The charger comes with alligator clips which you clip to the terminals of your battery. You can also charge your battery through the cigarette lighter port in your car.

There are usually two types of solar car chargers that are on the market. The first solar charger has a regulator which controls the charge that goes into the battery. The advantage of the regulated solar charger is that it prevents overcharging of the battery. The regulated battery chargers are used to ensure that your car battery does not drain when you leave the car for long periods of time. The second type of solar charger does not have a regulator.

Features of The Solar Car Battery Charger


1. Prevent Overcharge or Discharge of Your Battery

Any solar car charger worth its salt should come with a mechanism to prevent your battery from overcharging or discharging. Some have a regulator that prevents overcharging. For other brands, you have to set the current that you want to flow into your battery.

2. Ample sized wires and connectors
You might find yourself in a situation where you need to move the solar panel of your charger a long distance. A charger that comes with long wires and connectors is very ideal for such situations. The long wires will enable you to place the panels in the optimum position.

3. High Powered chargers
There are solar power panels that have a high resolution and can convert the light to power even in an overcast sky. Ideally, all solar panels can do so, but their power output is greatly reduced. You should buy solar battery chargers that are designed to work in low-light situations.

Benefits of The Solar Car Battery Charger

One of the greatest advantages of the solar car battery charger is its portability. You practically move with it wherever you go and can charge your car battery on the move. Another advantage is that the charger does not require an external source of energy, unlike the electric charger. This makes it cheaper since you do not incur additional electricity costs.

With proper usage and maintenance, the charger is guaranteed to give you service for a long period. Since you can use the cigarette port to charge your battery, you need not worry about fixing the alligator clips to the battery terminals- just plug the charger in ad off you go!

Conclusion

The portable solar car battery charger is not only effective, but they are also efficient. With the ease of portability and use, it makes sense to grab one for yourself. With a solar car battery charger, you no longer have to worry about your car not starting due to a low battery.
