Benefits and utility of solar battery charger



A solar battery charger is a new type of charging equipment that is mainly designed for travelers. For example, if there is no good power point in the mountains, we can use solar energy. With a solar battery charger, solar energy is converted into electrical energy for use.


1. The principle of a solar battery charger

A solar battery charger is a piece of equipment that uses solar energy for charging. Its working principle is to convert solar energy into electrical energy, and then output current to recharge the battery or charger. It can be used on various occasions, such as camping, travel, outdoor sports, etc., and is gradually accepted by people.

The solar battery charger consists of a natural light panel, a control circuit and an output interface. Natural light panels are the core components, generally using silicon light to absorb light and convert it into electricity. The solar charger's natural light panels need to work with enough light, and the stronger the light, the more electricity it converts.

The intensity of direct sunlight is the best working state of the solar battery charger, so it is best to use it when there is plenty of sunlight. The control circuit of the solar battery charger controls the magnitude and direction of the output current, ensuring that the light can be converted into electricity.

The output interface of the solar charger is a bridge between the charger and the charging equipment, which can convert electrical energy into output current, and input the electric energy of the charger into the charging equipment, and then the charger will charge the charging equipment. Through the output interface, it can be adapted to a variety of charging equipment.

2. Advantages of solar battery charger

In addition to the principle of operation, solar battery chargers have many advantages.

Advantages of solar battery charger

  • No grid support is required, only sunlight is needed to charge, which is very convenient outdoors.
  • Can be designed in a compact form, ideal for outdoor use.
  • It is a green energy source, causes no pollution to the environment, and has very good environmental performance.
  • No additional energy consumption is required, energy waste can be reduced, and it is a very energy-saving charging method.

In short, the principle of solar battery charger is to convert solar energy into electrical energy, and then output the electric energy to the charger or rechargeable batteries, becoming a convenient, practical, environmentally friendly and economical charging method. In the future, solar battery chargers will gradually replace the traditional charging method and become a popular charging method.

3. What are the charging methods of solar battery charger

● Powered by solar energy

What are the charging methods of solar battery charger


Place the charger in direct sunlight, and the solar energy will be converted into electricity to charge the lifepo4 battery built into the charger. Under sufficient sunlight, it takes about 8-16 hours to fully charge the lithium batteries.

● Alternating current

Connect the charger to the AC adapter, about 2–3 hours to fully charge the lithium battery.

● Adopt computer USB interface

Connect the charger to the computer with a USB cable, and the lithium batteries can be fully charged in about 2–3 hours.

4. What are the precautions for use

Do not damage the surface of the solar panel. When charging a rechargeable battery, place the solar panel facing up in direct sunlight to ensure optimal charging. Do not place the charger in water. When full, it should be removed from the bright light immediately.

What are the precautions for use


It cannot be placed in a high temperature environment for a long time, which will reduce the service life of the power supply. Do not put the solar battery charger behind the glass to receive sunlight use, especially in the car, glass has a refracting effect on sunlight, so sunlight can not be fully utilized.

5. How to choose portable solar charging equipment

Solar charging gear is a very useful tool for long-distance backpacking trips, allowing you to easily charge your electronic devices such as GPS, outdoor watches, headlamps, or smartphones. It can not only be used for home energy storage. Due to the dependence of many backpackers on outdoor electronic equipment in recent years, portable outdoor solar charging panels have become very popular.

Solar charging panels absorb sunlight and convert it into electricity to charge electronic devices or battery packs. Unlike regular batteries or power banks, which sooner or later run out of power, solar battery chargers are suitable for long-distance travel because as long as there is sunlight, they can charge the device. What should I pay attention to when choosing outdoor solar charging equipment?

● Type

There are three types of solar charging equipment: photovoltaic panels only, photovoltaic panels with integrated battery packs, and photovoltaic panels with removable battery packs.

● Photovoltaic panels only

The most popular way to charge is to use a solar battery. You just need to connect the solar panels to your device and the device will be filled with sunlight energy. However, before buying this solar battery charger, make sure it is compatible with your device (connector type).

● Photovoltaic panels with integrated battery packs

These solar chargers are usually very compact – the solar panel and battery pack are all in one. Therefore, they are great for extra backpacks. The downside is that they are not modular. You cannot use a battery pack without solar panels or a solar panel without a battery pack.

How to choose portable solar charging equipment


● Photovoltaic panel with removable battery pack

These solar battery chargers are basically photovoltaic panels with a battery pack. Of course, you can also use the included battery pack.

● Dimensions and weight

The output of a solar panel is measured in watts, the greater the number of powers, the more electrical energy is output, and the larger (heavier) the solar panel, the faster it can charge the battery pack. However, smaller or lighter solar panels are easier to pack and carry. This is also an important factor that everyone needs to weigh, and it is most important to choose the size that suits you according to your own power consumption.

● Flex vs hard

There are two types of backpack solar panels: rigid and semi-flex. Semi-flexible solar panels are foldable for easy portability. When you need them, you just have to spread them out and face them towards the sun. The main advantage of semi-flexible solar panels is that they have a large surface area, despite being very small when packed.

● Battery pack

While only solar panels can charge the device directly, charging with a battery pack is much more convenient. The battery hookup can store more power, allowing you to use it to charge your device when you're not in the sun.

Battery packs differ in terms of storage capacity and output power. Storage capacity is measured in milliampere-hours, and the larger the storage capacity, the more times the device can be charged. However, larger storage capacity also increases the weight and size of the battery pack.

● Solar panel compatibility

When choosing a solar battery charger, make sure it is compatible with the electronic device you plan to use. The vast majority of solar panels and battery packs are equipped with USB ports that can be matched to most smartphones and tablets. It is also important to choose a solar charging system with enough ports to meet your needs.

6. Conclusion

Solar battery charger in everyone's daily use is very convenient, and environmental protection and energy saving, but also the use of new energy, and its process of converting solar energy into electricity, will not harm the environment forever, so you can use it with confidence when you use it, but do not always put it in direct sunlight. Although it is a solar battery charger, long-term irradiation, not conducive to its long-term use in the future.
