1. Precautions for charging and discharging
The power bank generator is a portable charger that integrates power supply and charging functions with the rapid development of smartphones. You can charge or stand by for mobile phones and other digital devices anytime, anywhere. With the power bank generator, the problem of low battery life of digital products can be largely solved, so that the sudden power failure of digital products is no longer crazy. Power bank generator has gradually become a good helper for our daily necessities and digital products. However, the power bank generator is a new type of battery product, and many consumers still have many misunderstandings about the use and maintenance of the power bank generator. Today, I will share with you the precautions for using the power bank generator.
1. Cells
The core components of the power bank generator are mainly composed of two parts, one is the medium that stores electrical energy, and the other is the medium that converts other energy into electrical energy. Therefore, the quality of the battery can be used as one of the important criteria to measure the quality of the power bank generator.
There are three types of batteries commonly used in power bank generators: polymer lithium batteries, 18650 lithium batteries, and aaa nickel-metal hydride batteries.
Polymer battery: standard voltage 3.7 V, many shapes, can be customized, large capacity, fast charging, high quality and low price, widely used, such as: mobile phones, MP4, portable speakers.
18650 lithium battery: standard voltage 3.7V, with small size, large capacity, standard voltage 3.7V, mainly used in high-end products such as notebook computers.
AAA NiMH battery: standard voltage 1.2V. The capacity is relatively small. Should be widely, household appliances, players, etc. Polymer lithium-ion batteries are more expensive than ordinary lithium-ion batteries. However, the advantages of high capacity and small volume of high-capacity polymer lithium batteries make it gradually replace ordinary lithium batteries.
Charging Generally speaking, the power of the newly purchased power bank generator is very low when it is used for the first time, so it is best to re-use the power with a full charge for the first time after purchase, which helps to improve the efficiency of the built-in lithium battery of the power bank generator. It's normal for the power bank generator to generate some heat during charging or discharging, but if your power bank generator is hot, there is a problem, it may be a problem with the charging circuit. Therefore, the purchase of a power bank generator must have overshoot and overdischarge circuit protection, the battery must be produced by a regular manufacturer, and the battery produced by a small factory must not be considered.
2. Discharge
The large capacity of the power bank generator will become the future development trend of the power bank generator. The higher the capacity, the longer the battery life. However, the capacity is large, the volume-to-weight ratio is increased, the safety problem is also prominent, and the charging time will also increase accordingly.
2. Daily maintenance
1. Commonly used power bank generator
The point of maintaining a power bank generator is to keep the electrons moving. The way to maximize effectiveness is to use it often. If you don't use it frequently, please remember to charge and discharge the power bank generator once a month.
If you do not plan to use the power bank generator for a long time, it is best to store it with 50% battery power. Storing the battery at empty capacity will render the battery too deeply discharged to withstand any charge. Conversely, if the battery is fully charged and stored, the battery loses some of its charge, which shortens the battery life. Another point to note is that the power bank generator is often used as a "fast charge", mostly for emergency charging. Prolonged use may have adverse effects on your phone's battery. So we try to avoid excessive use of the power bank generator as a power source. However, it is more convenient to use the power bank generator to charge digital gadgets while traveling or traveling.
3. Storage
Although the power bank generator is safer and more stable than ordinary batteries, it will not explode as frequently as ordinary lithium batteries, but it must be properly stored.
1. Do not place the power bank generator in extreme environments: high temperature, collision, etc. are all important causes of battery explosion. Try to store the battery in a stable environment away from high temperature places. If you use the power bank generator in an environment 40°C above the specified ambient temperature, the battery level will continue to drop. That is, the power supply time of your power supply will continue to decrease.
2. The power bank generator avoids contact with metal materials, causing unnecessary short circuits.
3. Store in a place that is not easily accessible to children.
Fourth, the disposal of waste batteries
For the unusable power bank generator, please contact the manufacturer for repair, or comply with local environmental protection laws and related laws.
