Is there a long life power bank?

Now the power bank is generally a lithium battery, the life is about the same, only the difference in the size of the capacity, if you want to use it for a longer time, buy a larger capacity,

The service life is about the same, no matter which one is used frequently, it is easy to break, because the service life is related to the number of charges.

If the power bank has a long life, it is necessary to buy a good brand, and the battery capacity of the general brand power bank is enough, and the voltage is stable, so it is more durable.

Under normal circumstances, the service life of the power bank is about 3 years.

In addition to good cells, large capacity, and excellent circuit boards, paying attention to the characteristics of the power bank and taking good care of it will make the power bank more durable.

The power bank will also be afraid of cold and heat, so you should pay attention to the temperature of use. The operating temperature of lithium battery is 0-55°C. When the outside temperature is too low, the battery will work unstable and the discharge will not be sufficient.

High temperatures, in turn, can shorten the life of electronic devices, damage batteries, and age some plastics. These problems are mainly concentrated in winter and summer, and the weather in the border areas is more extreme, so it is worth paying attention to.

In daily life, the inside of the car, backpack, etc. is a relatively closed environment, because the convection is relatively poor, if the charging treasure in the state of charging and discharging is placed inside, it is easy to cause local high temperature and cause.

Avoid charging and discharging at the same time. The problem of charging and discharging is mainly due to the high load on the circuit board and the high temperature generated in a short period of time, which affects the performance and safety. In addition, when we see that the nominal input value of the power supply is 5V 1A, and the output value is 5V, it is easy to form a phenomenon of making ends meet, and the internal parts of the power bank are greatly damaged.

Watertight. To be clear, the power bank does not have a waterproof function, so once the water enters, it is easy to cause the product to be unusable. In daily life, it is easy for the power bank to get into the water due to dampness on rainy days, accidentally falling into the water, or using a damp cloth for cleaning, which will cause leakage, short circuit or other faults.

How long the power bank can last depends on the number of full cycles you have and how you usually use it. The impact on the life of lithium batteries is overcharge, overdischarge, and high temperature (50) or more.

Overcharge is mainly due to the failure of the charging circuit to judge the battery voltage, and the battery voltage is still recharged after reaching the highest level, thus causing overcharge.

Over-discharge is when the discharge circuit fails to stop discharging when the battery is discharged to a defined minimum voltage, resulting in permanent damage. Another reason for over-discharge is that the power bank is idle for a long time, and the battery is self-discharged to below the limit of low voltage, which requires that if the power bank is not used for a long time, the power of the power bank will be charged to about 60% and then placed for a long time, and it will be charged every six months to ensure its power level.

Lithium battery charging and discharging at high temperature will affect the life, and there is danger, qualified power banks are equipped with temperature probes, in case the above situation occurs, stop the charging and discharging process in time.

Therefore, in addition to its own various limitations, the user's good use habits can ensure a long service life.

Generally, the total capacity of lithium batteries becomes 80% of the factory capacity after 500 full charge and discharge cycles, and it can still be used after that.

Because the biggest influencing factor affecting how long the power bank can be used is the battery cell. Let's take a look at a lithium cobalt oxide cell, the number of cycles is about 300 times, and the better one is 500 times of charge and discharge, 800-900 times The real number is rare, and more than 1000? Hehe.

Under normal circumstances, as long as you meet 500 times of charging and discharging, the power bank can be considered, after all, from the first or the use of time to consider this kind of mobile power supply is quite suitable for ordinary consumers.

3 high-energy LG batteries composed of Secretary Treasure power bank.

Take a power bank with a capacity of 5000 mAh as an example, according to the standard of 500 times of charging and discharging, and then calculate the frequency of 2 days of charging, it can be used for 1000 days, about 3 years or so, of course, the service life will be longer if it is used and maintained.

Internal structure of lithium iron phosphate battery.

The working principle of lithium iron phosphate batteries.

In addition, what brand of battery cells used is also very important, basically the quality of the battery cells produced by the international manufacturers Samsung, LG, Sony, and Panasonic is very good, and the technology is mature and the product performance is excellent, which has won the love of many consumers. There are also good battery cell manufacturers in China, if you are interested, you can search for relevant information by yourself. Class A cells are the highest quality, so they last longer.

However, it is best not to choose Class B and Class C cells, which is difficult for consumers to judge their categories. It doesn't matter if you still recognize the brand! Good battery cells are more expensive, and they are often produced by some big brands, and the chance of problems is very low.

The impact is very large, because there are many inferior power banks on the market now, and the current it provides is not very stable, so it has a great impact on the battery life of the mobile phone. If it is really not necessary, it is recommended not to use a power bank.

21.The lithium battery used in smart phones has a certain demand for temperature, and overheating or overcooling can easily cause slow charging.

32.If the charger is in poor contact, replace the charger and then charge the phone.

43.If the battery is damaged, use the software to check the battery.

54.Too much background running on the phone will also cause the phone to charge slowly, so clean the phone in time and charge it.

6. A battery is a cup that contains an electrolyte solution and metal electrodes to generate electricity. A device that converts chemical energy into electrical energy in a tank or part of a container or composite vessel. with a positive electrode.

The negative pole is divided. With the advancement of technology, batteries generally refer to small devices that can generate electrical energy. Such as solar cells.

The performance parameters of the battery are mainly electromotive force. Capacity. Specific energy and resistance.

Using the battery as energy, you can get a stable voltage, stable current, long-term stable power supply, little influence from the outside world, and the battery structure is simple, easy to carry, simple and easy to charge and discharge, not affected by the outside climate and temperature, stable and reliable performance, and plays a great role in all aspects of modern social life.

Not too. Because the output standards of the power bank are in line with the national standard, it is similar to direct charging, so it has little impact on the battery life of the mobile phone.

If you often use a power bank to charge your mobile phone, the impact on your mobile phone must be very large. In particular, the impact on battery life is the greatest, and it is easy to cause battery damage.
