There are currently five common types of mobile power supplies:
Type 1, a mobile power supply with lighting function, has built-in energy-saving super LED lighting, which is very energy efficient. If it is only used for LED lighting, it can be used for 3 hours to 30 hours or even more depending on the capacity of the built-in battery. It depends on the battery capacity of the mobile power supply.
Type 2 is a mobile power supply with only charging function. This charger does not have other extensive functions. The advantage is that this type of charger has a large capacity and is very suitable for professional external power supplies.
Type three, a mobile power supply with a solar panel, can be charged by sunlight during use to achieve the purpose of energy replenishment. This type of mobile power supply was previously mainly uUsed in special forces and special industries. For civil use, as the conversion rate of solar panels gradually increases, they gradually become popular.
Type 4 uses flexible and flexible monolithic integrated circuit PV thin-film solar panels to store lightweight and flexible (6 photos) supplies solar energy in batteries, and can also directly transmit the Electrical energy converted from solar energy to electronic devices. . It can maximize energy capture efficiency even in poor light conditions. It has the advantages of being foldable and waterproof. Compared to other solar products, it is more flexible and lightweight.
Type 5, the highest quality and safest mobile power, produced with the latest technology and the safest lithium polymer cells, stores energy in the battery cells and ttransmits energy higher and faster to electronic equipment. can be charged and used at any time, and it can be charged while charging. It has the advantages of convenience, security and protection. Compared with other mobile electrical products, the safety is the highest.
Different types. mobile energy cores, in short, the components have two parts. One is the medium that stores electricity and the other is the medium that converts other energies into electricity. Therefore, the quality of battery core can be used as one of the important criteria to measure the quality of mobile power supply.
Are there high capacity chargers?
The solar panel can directly charge the mobile power supply, and the power bank's own circuit has a voltage stabilization module.
1. The concept of “mobile power” was developedppe 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 low rate is even only 30%. If the conversion rate is lowerat 75%, this means that the mobile power circuit has a significant loss and the battery core itself generates a large amount of heat.
Solar chargers use solar energy to directly charge laptops, cell phones, digital products and other directly charged solar products.
Genuine 4W/5V solar charger (USB output interface) produced by GS-SOLAR - weight (138g), output current is above 600mA under normal circumstances, it can charge Nokia mobile phone with a 750mAH battery, if there is enough sunshine. Full charging only takes a few tens of minutes (at midday), less than an hour. Currently, mobile phones available in the market can be fully charged in 3 hours.
Many solar chargers currently on the market are concept products. Why do you say that? Because theyare all wearing high-tech solar-powered outerwear, but it is basically a mobile power supply. The solar energy on such a solar charger (Power Bank) is for decoration and does not exert the true power of solar energy. Let's take an example:
There is a 2600mA model on the market equipped with a 0.4W solar panel (the actual capacity is much smaller, many are less than half). If the solar panel wants to charge mobile power, the minimum voltage should be 3.8V for floating charging. In this way, under the standard test lighting (1000W/square meter, AM1.5), the maximum operating current is only 100mA. . If this mobile power supply, the built-in solar panel charges the battery, which takes more than 26 hours under testing conditions. In our daily living conditions, the lighting is lower than the standard test lighting,so the normal working current of the solar panel of this mobile power supply is less than 80mA, and the actual output current is even smaller, generally less than 60mA. . Therefore, the solar panel of this mobile power supply needs to be left in the sun for 44 hours to fully charge the battery. If you can get 11 hours of sunlight per day, it will take 4 consecutive days for a full charge. If you really leave it in the sun for such a long time, the mobile power supply will be significantly damaged. It is possible that the battery of this mobile power supply may explode. Therefore, the solar panel equipped with this mobile power supply is just an embellishment.
So when buying a solar charger, you should buy a real solar charger.
