What Is A Solar Charger?

When you hear of a solar car charger, the first thing that comes to mind is, “WHAT IS A SOLAR CHARGER?”… This article will help you solve that curiosity with a detailed explanation of all you need to know about Solar chargers.

A solar charger is a charger that uses solar energy to supply electricity to devices or batteries. More so, they are generally portable.

However, solar energy, in this regard, converts sunlight into usable energy forms. Even so, several steps are involved in catching the energy that comes from the sun and converting it into electrical energy.

In addition, photons from the sunlight help carry enough energy that pushes the electrons from their orbit in some elements(silicon).

Furthermore, solar battery chargers do not charge the lithium-ion battery in your devices directly. Instead, it charges an internal rechargeable battery in the device.

Hence, it is charged through the solar modules and then distributed to your gadget to avoid requiring an external electrical source.

5 Best Car Solar Chargers: Pros And Cons



Solar battery chargers are usually very light and portable. Hence, they are easy to be carried about. On the other hand, it often weighs four to five pounds, making it easy to use and not burden the users.


Unlike standard chargers that require an outlet, a solar battery charger works theoretically when the vehicle moves. You can conveniently plug the 12-volt socket into the car’s dashboard and position the solar panel on it to absorb the maximum sunlight.


Solar chargers are useful for car batteries, standard boats, ATVs, personal watercraft, and any vehicle that uses a 12-volt battery. Also, it has alligator clips that can be attached to battery terminals directly.

It Is Self-contained

A solar battery charger requires no outside power source to supply the battery with a charge because it is powered by the sun.

Even so, it converts absorbed solar energy into DC power and then transfers it immediately to the battery, thus, keeping it charged and prepared simultaneously.


A solar battery charger can operate during all weather conditions, from temperatures beyond 120 degrees Fahrenheit or even more. This means that the solar battery charger will work even when it is freezing in the middle of summer.

Also, they are low-powered. Hence they work well as maintenance chargers.

Even so, it is eco-friendly. Thus, it helps you to reduce your carbon footprint.

More so, it can help prolong a stationary vehicle’s life cycle.


  • A solar battery charge also has some disadvantages that serve as a drawback to its benefits, and they include:
  • The power of a solar charger cannot be compared to that of a regular battery charger. This is because they are not as powerful as regular battery chargers. Hence, it takes more time to charge the batteries.
  • Also, it gives out minimal current; it is more useful for maintaining a charge than charging a completely drained battery.
  • However, you must be cautious if relying solely on a solar battery charger.

Factors to consider When Buying The Best Car Solar Chargers


Solar chargers are available in different sizes. Therefore, the more power you need, the bigger the size of the charger.

For a car battery, you may need to buy a 12 Volt battery charger as it’s usually easy to carry and lightweight.

You can keep it inside the car and carry it around easily. Moreover, it has enough capacity to sustain bigger things like cars, bikes, boats, etc.

Cables And Connectors

You tend to have various options when you have a solar battery charger with multiple connectors. Also, you must consider the size of the power cable.

The solar battery charger is a fantastic idea that may help us become more environmentally conscious by harvesting solar energy. As a result, investing in it may be the best way to reduce your carbon footprint and make the most of the sun.


Solar battery chargers typically range from 2 to 18 volts. As a result, those with higher powers may be charged rapidly, while those with lesser powers do not risk overpowering your battery.


This is important because an efficient battery charger harnesses solar energy quickly. Thus you do not have to worry about not getting enough sun.

Therefore, they are also useful in winter when you have comparatively less sun.
