With the popularity of smartphones, people’s dependence on mobile phones is deepening. When going out for shopping, dining, payment, navigation, riding, etc., they cannot do without their phones. Running out of battery has become the norm. Therefore, a portable power bank has become an essential item for going out. However, with the rise of outdoor sports, what should be done when both mobile phones and power banks run out of battery in the wilderness? Some outdoor charging products have emerged, and solar phone chargers are a typical example.
What is a solar phone charger?
It is a self generating charger specifically designed for mobile phones, compact and portable, usually a small foldable solar panel, equipped with one or two USB ports. By connecting the USB ports to the phone, it can charge the phone.
How does a solar phone charger work?
A solar phone charger is a device that converts light energy into electrical energy through solar panels. Its working principle is based on the photovoltaic effect of semiconductor PN junctions. When sunlight shines on the semiconductor material of the solar panel, it causes a voltage difference in the PN junction, which forms an electric current and provides power for electronic devices such as mobile phones
What is the difference between a solar charger and a solar power bank?
There are certain differences between solar chargers and solar power banks. Nowadays, many solar power banks on the market cover a layer of solar cells on top of the original power bank as a supplement to electricity, and do not rely heavily on solar energy. A fully solar powered mobile phone charger does not include a battery and requires sunlight to charge the device, making it suitable for use on airplanes and high-speed trains. Of course, in order to better utilize solar energy, it can also be paired with energy storage batteries.
How to choose a reliable solar phone charger?
- Surface material
Outdoor products, in addition to being lightweight and easy to carry, must use materials that are waterproof, wear-resistant, and not easily damaged, because outdoor environments are usually difficult. Solar chargers with good surface materials are sturdy and durable, and can provide you with reliable electricity. - Solar cells
At present, solar cells on the market are mainly made of silicon as the raw material, divided into monocrystalline silicon and polycrystalline silicon. In terms of photoelectric conversion rate, monocrystalline silicon solar cells have the best conversion rate, with monocrystalline silicon>polycrystalline silicon>amorphous silicon. The larger the area and power of solar panels made of the same material, the greater the output current. As an outdoor use, an efficient charging pad is the best choice. Nowadays, the quality of solar chargers on the market varies greatly. It is recommended to choose a brand with quality assurance.
Gaotu Innovation has been focusing on the research and development, production, and sales of solar panels for 18 years. All of its products have passed international authoritative certifications such as T Ü V, CE, FCC, RoHS, REACH, and PSE. We offer a wide range of solar panel chargers with power ranging from 5W to 100W, accurately matching the electricity needs of various scenarios such as hiking, camping, photography, etc., providing you with safe and reliable outdoor power solutions. - Intelligent voltage regulation, intelligent restart
Solar powered mobile phone chargers can output electrical energy under direct sunlight, but once the battery cells are obstructed, they will lose power, which is a major drawback of solar powered chargers, especially when traveling outdoors, it is necessary to constantly monitor whether they are charging. Fortunately, with the development of technology, some solar chargers have the functions of intelligent voltage regulation and intelligent restart, which can effectively protect the phone and automatically restart under light, saving time and effort.
