Do you often receive complaints from users about fast power down, short service life, slow charging and a series of problems. These problems are not only about the user ‘s experience, but also about the brand ‘s crisis of confidence. This paper sorts out the top ten high-frequency problems of power bank  that consumers hate most, and helps you find user pain points accurately. In order to avoid market risks in advance and enhance the reputation of the brand!

The top ten high frequency problems of power bank are as follows! Let’s get to know!

1 Security issues

Safety is the bottom line, which is related to the personal and property safety of users. Poor cell quality, protection circuit design defects, production process fluctuations, etc., will lead to bulging, thermal runaway and other issues, resulting in security risks.

Recommendation: Require the power bank factory to provide the latest standard battery test report, and the production process of the full inspection capacity data report. Comprehensive evaluation of power bank protection circuit design and fast charging heat management capabilities. Whether to carry out 100% aging test before leaving the factory.

2 Capacity virtual scale

The capacity virtual mark is also the most problem for users to spit. It is necessary to ensure that the power bank has no capacity virtual target problem.

Recommendation: pay attention to the actual discharge efficiency of the power bank, the discharge efficiency is too low means that the loss is too large. Require the power bank factory to provide the latest standard of finished product test report!

3 Charging speed is slow

The slow charging speed seriously affects the user’s charging experience. Therefore, it is necessary to determine the appropriate fast charging according to the target user, and do not let the charging speed be the reason for the complaint.

Recommendation: Confirm whether the factory can provide detailed fast charging protocol compatibility test reports and ensure mass production consistency. It is required to provide a full inspection function test list of mass-produced finished products, including fast charging function!

4 Short service life

Many consumers have bulging and unable to charge after charging for half a year or one year. Therefore, at the beginning, we should pay attention to the cycle life of the battery and predict the service life of the power bank. Normal power bank can be used for several years.

Recommendation: Do not use inferior batteries, confirm how many times the measured cycle life of the battery is. The capacity retention rate of the battery after a specific number of cycles (such as 500 cycles) is ≥ 80%. Ask the power bank factory whether can provide cycle test report!

5 Charging intermittent

Intermittent charging is also one of the problems for users to spit. The problem may be that the compatibility between the power bank and the mobile phone is not good, so there will be automatic disconnection, or intermittent charging.

Suggestion: The internal resistance of the cell is inconsistent or the circuit design is not good, resulting in a sudden drop in voltage when the current load is large. In the sample test stage and the full inspection of the mass production function, the focus is on the load voltage stability of the power bank, and whether there will be power failure!

6 power bank has virtual electricity

The virtual electricity is mainly manifested in the problems of fast power down and unsustainable charging. It is obvious that the display power of the power bank is seriously inconsistent with the actual available capacity. The most fundamental problem is that the battery aging, premature capacity attenuation.

Recommendation: At present, the power display is usually calculated by Coulomb meter, and the display accuracy is higher. But it’s best to confirm this information. Of course, the quality of the battery is the foundation!

7 Inconvenient to carry

Too heavy, too large, unable to carry on the plane, high-speed rail, subway, etc., are the focus of consumers. How to balance the capacity and volume is a problem to be considered.

Suggestions: Before cooperation, it is suggested that the factory should provide space optimization cases. Then compare with the same capacity of peers, and confirm whether to provide integrated design schemes such as self-contained lines and folding plugs to increase portability.

8 Self-contained line is easy to break

About the self-contained line power bank, because the self-contained line is frequently used, there will also be a problem of capacity fracture. Therefore, this issue needs to be taken into account.

Recommendation: Whether the self-contained cable provides a swing test. For high-end models, it is recommended to ask whether after-sales service can provide a change of line to deal with small probability of damage. In addition, it can also be considered whether the self-contained line uses a braided line!

9 Poor compatibility

At present, consumers have many electronic devices, and the brands of various devices are inconsistent. This is to consider the fast charging compatibility of the power bank. Poor compatibility is also one of the problems that users often spit.

Recommendation: It is necessary to provide the specific compatibility test report of the equipment. The report needs to reflect the detailed current, voltage, etc., clearly compatible with which mainstream models!

10 Current nourishing sound

It is a problem raised by many consumers that the current sounds when charging. This would have been a normal phenomenon. But if the current sound is relatively large, consumers may not understand. It will also be worried when used.

Suggestion: Experience the prototype in person and feel whether the current sound is obvious. Assess the impact of current sound!

The above are the top ten problem points of power bank that consumers hate most. In addition to the above, there are other things to pay attention to. It is recommended to choose professional and reliable  power bank source manufacturers to cooperate. The comprehensive strength is strong, the probability of problems will be smaller, and after-sales service will be more secure!
