6000mah 3.2v lifepo4 battery.What are the purchasing tips for mobile power charging banks

　　Which brand is good for mobile power supply? When it comes to the purchase of mobile power supplies, it is actually a relatively broad concept. The author can only provide a few practical suggestions here, and rely more on consumers' own eyes to observe and judge.

　　Firstly, it is best to choose a well-known brand. Most people lack knowledge of mobile power sources, so for safety reasons, it's better to spend more money on buying high-end mobile power sources. This prevents accidents and ensures the quality of enjoyment. Just refer to the mobile power leaderboard.

　　Secondly, choose a suitable mobile power source for yourself. The capacity of a mobile power supply is closely related to its size. Generally speaking, mobile power supplies below 3000mAh can only charge the phone once, making them suitable for ordinary office workers. For those who want to travel for a short period of time, it is best to choose a mobile power supply with a capacity of 5000mAh or above. Of course, the larger the capacity, the better. The larger the volume and weight, the more inconvenient it is to carry. Moreover, ordinary quality large capacity mobile power supplies have an impact on human safety and are not recommended for use.

　　In addition to capacity, when purchasing a mobile power supply, it is also important to pay attention to whether the interface matches, otherwise it will be a waste of money. Different mobile phones or tablets have different interfaces, so when choosing a mobile power supply, it is also important to choose the interface you want.

　　Finally, pay attention to the workmanship and quality of the mobile power supply. The workmanship of a good mobile power supply is very meticulous, and the quality can be seen at a glance. Of course, the more important thing is its power conversion rate. Generally speaking, it cannot be converted 100%, and the conversion rate cannot be lower than 70%.
