Portable mobile power, also called "external battery", "external battery", "backup battery", "digital charging companion", the concept of mobile power is developed with the popularity and rapid growth of digital products, the definition is convenient Easy to carry large capacity portable power. The functions of digital products are increasingly diversified and used more frequently. The question of how to improve the use time of digital products and maximize their functions is important. Mobile power is the best solution to solve this problem. With a single power supply, you can supply power (power or charge) to a variety of digital products anytime, anywhere.
The capacity of the mobile power supply varies from 2000 to 20000mAH, and generally exceeds 18000mAH to supply power to the notebook computer. It is generally called universal mobile power. Less than 10,000 capacity, generally small size, are called portable mobile power, mainly used to charge digital products. The leading brand is Pinsheng Mobile Power.
How to use portable power
A. the output voltage of the mobile power supply must be within the range of 5.3V ± 0.5V, otherwise it can not charge some brands of mobile phones;
b. The transfer joint must be matched. The principle of using the mobile power product is to charge the digital device through the USB cable. The end of the cable with the USB interface is connected to the mobile power product, and the other end is connected to the digital device, so the interface at the other end is Must be consistent with the interface of the digital device, otherwise it will not be able to charge.
c. The mobile power supply should be handled in a dry environment. Rain, moisture, and various liquids or moisture can corrode electronic components and circuits.
d. The mobile power supply cannot be stored at high temperatures. High temperatures will shorten the life of electronic devices, damage batteries, and age certain plastics.
e. You cannot throw and tap the mobile power supply in a rough way. Rough use can damage internal boards and precision machinery.
Mobile power usage precautions
1. avoid falling, especially careful not to squeeze
Products such as electrical appliances have always been unable to withstand bumps, and mobile power supplies are no exception. Small mobile power supplies are actually complex battery cells. When they are bumped or squeezed, they can break the components inside, especially some people like to go with them. Put the mobile power under the seat, or put it on the bedside table, and press it with various magazine books. Please note that this is a cell that can easily damage the mobile power supply.
2. pay attention to temperature and humidity
I think everyone has had such an experience. If the weather is wet, especially when going back to the South, the TV will turn a little blurry and the color will be distorted. This is the effect of humidity on the appliance. Of course, mobile power is no exception, so try to avoid storing the mobile power in an environment where the temperature and humidity are too extreme. If the weather is humid, you can use it more frequently and charge it. This is also a good way to protect it. method.
3. try not to use it without being fully charged
This is like the maintenance method of the mobile phone battery. The mobile phone battery generally does not advocate the use of the battery when the charging is not completed, and the mobile power supply is also the same. Before the mobile power source charges the mobile phone, you must first fully charge the mobile power itself. In the process, try to avoid interruption when the charging is not completed, because it will also damage its life.
