You will choose the value of the charging treasure or the capacity, charging treasure is not just as simple as charging, you will buy a bomb if you buy the wrong! With the advent of mobile phone charging treasure, the magic of the battery has been solved for smart electronics. However, many consumers can't help but ask if the mobile phone charging treasure will damage the battery.
Those brands can be considered
I think the most important first thing about charging treasure is safety; the second is the cycle performance, which is the capacity decay during use.
The main components that determine these two points are the battery cells, and the batteries of the charging treasure are divided into two types:
1. 18650 battery core (the advantage is cheap, safe; the disadvantage is that the volume is large, the cycle performance is poor). The reason is 18650 battery, because 18 means the diameter is 18mm, 65 means the length is 65mm, 0 means cylindrical battery Currently, the main battery manufacturers in the industry are Panasonic, Sony, Samsung and LG. Among them, Sony's quality is the best, Panasonic is second, and the two Koreans are almost the same. Xiaomi uses the batteries of Samsung and LG. Although the quality can't be said to be the best, it is not much better than the brand-name batteries used by the Romans. It seems that I have never heard of the Panasonic and Sony's charging treasure brand, so the 18650 charging treasure is still good for Xiaomi. (provided by desperado)
Poor quality charging treasure is the main murderer of your mobile phone
Poor quality charging treasures are filled with small shops and Taobao stores. Those colorful, yet cute, low-cost charging treasures are very pleasing, but they are not seen by mobile phones.
The inferior charging treasure voltage is unstable, so that the output of the mobile phone is easy to cause various malfunctions of the mobile phone. And such a charging treasure itself is not safe. At present, there have been many accidents involving charging explosions, and these charging treasures are not products that are counterfeit or of poor quality.
Prevent overcharging, overheating, protect your battery
In fact, in the daily life of the mobile phone battery, it is best to use the mobile phone battery alarm when charging, because it is just when needed, just like people want to eat when they form a law.
Beginning in 2009, qualified battery equipment should be marked with the rated energy (Wh) of the battery, at least the capacity (Ah). The formula is Wh=Ah*V. For example, the commonly used charging treasure is generally 10000mAh, which is 10Ah. The output voltage of the general battery is 5V, and the rated voltage is 3.7V. Therefore, the rated energy of the general charging treasure is 3.7*. 10=37Wh (may also be greater than, in general, less than 5*10=50Wh);
When charging after the alarm, if there is no emergency when charging, it is best to wait for the battery to be full and then use or make a call, because the voltage is stable during charging, if it is used, the power will increase. The current is directly supplied by the charging treasure. If the quality of the charging control circuit you use is good, there is no problem at this time, but if the current of a control circuit slip is quite unstable, too large or too small will give the mobile phone. Internal circuits cause stress, and serious damage may occur at that time.
Short circuit protection
Most mobile power supplies use lithium-ion batteries inside. When users operate or use them improperly, the battery may cause a safety accident due to a short circuit. It has become a major hidden danger affecting the safety of mobile power.
There are many reasons for the short circuit of the mobile power battery, which is usually related to the product quality, the use environment and the daily use method of the mobile power source itself. As we all know, the charging cable used in mobile power supplies generally uses a PVC plastic sheath, which not only protects the internal metal wires, but also provides insulation.
Equipped with a short circuit protection program, the circuit will be turned off for the first time when a short circuit condition occurs. The more common short-circuit recovery methods adopted by mobile power are: automatic recovery, charging recovery, button recovery, and so on.
Overvoltage protection
As the complexity and integration of electronic systems become higher and higher, and the operating voltage is getting lower and lower, the requirements for reliability, stability and safety of electronic systems are getting higher and higher, and the importance of circuit protection design is also increasing. The stronger it is. In the circuit protection design, whether the selection and application of the circuit protection device is reasonable will directly affect the protection effect of the electronic system circuit protection scheme.
Reassuring for automatic recovery
When there is a fault inside the mobile power supply, the internal circuit will automatically adjust, the current will not be completely cut off, and the operation will resume automatically when the fault is eliminated. The charging is restored, that is, after the internal fault occurs, the short circuit protection is turned on, and then charged again. It can be restored; the button is restored, some products need to be activated by the opening key after short-circuit protection, which is divided into short press and long press, and the operation is relatively simple.
Small reminder: When using mobile power, you should avoid charging for a long time to prevent safety hazards caused by long-term charging; avoid using it in wet, too high or too low environment to prevent excessive moisture or knot inside the mobile power supply. The frost causes a short circuit; try not to use it under thunderstorms, and the mobile power source is prone to arcing, which may cause electric shock or short circuit.
Long-term use is in line with Chinese civil aviation regulations
Charging treasure refers to a lithium battery mobile power source whose main function is to provide external power to electronic devices such as mobile phones. According to the current effective ICAO Technical Regulations for the Safe Transport of Dangerous Goods and Air Traffic and the Regulations on the Administration of the Transport of Dangerous Goods for Civil Aviation of China, passengers carrying a charging treasure shall comply with the following regulations:
First, the charging treasure must be carried by the passenger personally.
Second, the charging treasure can only be carried in the carry-on baggage or carry it with you. It is strictly forbidden to carry it in checked baggage.
Third, the charging treasure rated energy does not exceed 100Wh, no airline approval; rated energy exceeds 100Wh but does not exceed 160Wh, can be carried after approval by the airline, but each passenger can not carry more than two charging treasure.
4. It is strictly forbidden to carry a charging treasure with a rated energy exceeding 160Wh; it is strictly forbidden to carry a charging treasure that does not indicate the rated energy and cannot calculate the rated energy by other parameters marked.
5. Do not use the charging treasure to charge the electronic equipment during the flight. For charging treasures with a start switch, the charging treasure should always be turned off during the flight.
Summary: The correct use of charging treasure can bring power to the mobile phone. At the same time, it should avoid safety hazards and reduce the damage to the mobile phone battery. This problem should be brought to the attention of everyone. Every year, because of the short circuit of charging treasure, etc. There are many accidents, and there are also examples of damage caused by explosions caused by inferior charging treasures. Therefore, the choice of charging treasures needs us more attention.
