How many milliamps does a power bank usually have? Hot topics and purchasing guides across the Internet

With the popularity of mobile devices, power banks have become a must-have for modern people when traveling. Recently, there has been a lot of discussion on the capacity of power banks across the Internet, especially how to choose a power bank with the appropriate mAh capacity. This article will combine hot topics in the past 10 days to provide you with a detailed analysis of power bank capacity issues and provide structured data reference.

1. Ranking of Common Capacities of Power Banks

2. Recent hot topics of discussion

1.Impact of new aviation regulations: Many airlines have updated regulations that power banks above 20,000mAh need to be declared separately, causing users to reconsider capacity selection.

2.Fast charging technology adaptation: The issue of matching fast charging protocols such as PD/QC4.0 and power banks with different capacities has become a hot topic in technology forums. The search volume for 10,000mAh products that support fast charging increased by 37%.

3.Controversy over environmentally friendly materials: The EU’s new proposal requires power banks to label their true cycle life, and the actual output of some products with a nominal capacity of 20,000mAh has been questioned.

3. Golden rules for capacity selection

4. Three major misunderstandings about capacity cognition

1.Nominal value ≠ actual output: Due to voltage conversion loss, a 10000mAh power bank can actually charge about 6000-7000mAh for a mobile phone.

2.Large capacity ≠ fast charging: If the 20000mAh product does not support the fast charging protocol, the charging speed may be slower than the 10000mAh fast charging model.

3.High density ≠ safety: A recent quality inspection report shows that some ultra-thin and large-capacity products have the risk of battery overheating.

5. Capacity comparison of mainstream brands in 2023

Conclusion:Choosing the capacity of a power bank requires comprehensive consideration of travel scenarios, equipment needs and portability. According to the hot discussion trend across the Internet, 10000-20000mAh is still the "golden choice" for most users, which can not only meet daily needs but also comply with aviation regulations. It is recommended to look for the PD3.0/QC4.0 fast charging protocol when purchasing, and check the actual rated capacity parameters rather than the nominal values.
