Mobile solar power supplies need to pay attention to the material of the battery core. Polymer batteries are better.
In order to reduce costs, many manufacturers on the market use lower quality 18650 batteries. If the quality isn't up to par, it's like carrying around a time bomb. Therefore, when purchasing a product, everyone should do so. Comprehensively consider the brand and price of the product. Don't settle for the cheapest. For polymer batteries, the biggest safety risks are liquid leaks and short circuits, which can lead to packaging expansion. In the worst case, a burn may occur. Compared to 18650 batteries, polymer batteries are relatively safer. However, combustion can also pose safety risks. It is therefore recommended that users of mobile power supplies tryPlease do not place the mobile power supply in a flammable environment.
In addition, the power generated by the mobile power of ordinary single-chip battery panels is relatively small, and it cannot be fully charged in one day. When purchasing, be sure to purchase a high-power mobile power supply.
The charging principle of mobile solar power is to convert the sun's energy into electric energy and store it in the battery of mobile solar power. When the mobile phone does not have enough power, the mobile solar power supplies the battery power to the mobile phone. However, mobile solar power can only be used in emergencies, and mobile phone charging cannot entirely depend on mobile solar power. If you need to use solar power bank to charge your cell phone for a long time in daily lifene, it is recommended to choose a solar panel of more than 0.7W, otherwise it will not have obvious charging effect.
What should you pay attention to when using mobile solar power? First of all, please note that when charging the mobile power under strong light, do not delay. It must be charged for at least 8 hours before the battery is fully charged. As we all know, it is still a bit difficult to get uninterrupted direct sunlight for more than eight hours a day. Second, do not place the mobile power supply in a car where the temperature is high, otherwise the battery life will be shortened. Try not to charge the mobile power by shining sunlight through the glass, because the effect is not obvious. Finally, be sure to charge the power bank under bright light and do not use chemicals to wipe the productit.
Although solar power banks are no longer a new term nowadays, they have their own advantages over lithium battery power banks and are widely used by a large number of mobile phone users. However, mobile solar power supplies still mainly rely on novelty to attract people's attention, and the advantages are not obvious from a current practical and technical point of view, the quality is very average, the charging speed is slow and power conversion rate. is weak
