1. For solar panels rated around 6V, an anti-reverse diode can be connected in series to charge the mobile power supply.
2. If the rated voltage is much higher than 6V, you need to add a conversion power board to reduce the voltage to 5V before charging the mobile power supply.
3. Current battery panels have low efficiency. An A3 size battery panel needs to fully charge a 10,000mAh mobile power supply. Due to the intensity of light in the northern hemisphere, this will take several days. on a sunny day. Considering the price, I can only say better than nothing, poor value for money.
4. There is another problem. Since the sunlight is strong during charging and the cable cannot be too long, the temperature of the mobile power supply is a problem. High temperatures can easily damage the lithium battery.
Can solar panels directly charge mobile power supplies? Does the power bank circuit have voltage stabilization?
1. This type of mobile power supply can be used in areas with relatively long sunshine hours, but its general applicability is not strong.
2. A mobile power supply with a solar panel can be charged by sunlight during use to achieve the purpose of energy replenishment.
3. This type of mobile power supply was previously mainly used in special forces and special industries. As the conversion rate of solar panels gradually increases, they have gradually become popular for civil use.
The solar panel can directly charge the mobile power supply, and the power bank's own circuit has a voltage stabilization moduleif we.
1. The concept of “mobile power” was developed with the popularity and rapid growth of digital products. Its definition is as follows: a portable power supply that is practical and easy to transport. As digital products have more and more diverse functions, are used more frequently and are more and more closely linked to our daily lives, it is even more important to increase the usage time of digital products, facilitate people's lives, replenish energy in time and optimize their functions. . Without delay.
2. Mobile power is the best solution to this problem. Carrying a mobile power supply with you can charge a variety of digital products anytime and anywhere.
3. The quality of mobile power supply mainly depends on the power conversion rate, which can reach about 80%. The regular rate is around 70-75%, and the lowthe is even only 30%. If the conversion rate is less than 75%, it means that the mobile power circuit has a large loss and the battery core itself generates a large amount of heat.
