How to Choose Power Bank Battery
When it comes to the purchase of mobile power, it is actually a relatively broad concept.We can only give a few more practical suggestions here, and more depends on the consumers' own eyes to observe and judge.
1. First of all, it is best to choose a well-known brand. Most people lack the knowledge of mobile power supplies, so for safety reasons, it is better to spend more money to buy big-name mobile power supplies. This prevents accidents and guarantees the quality of enjoyment. Just refer to the mobile power rankings.
2. Secondly, choose the power bank that suits you. The capacity of the mobile power supply is closely related to its size. Generally speaking, the mobile power bank below 3000mAh can only charge the mobile phone once, which is suitable for ordinary office workers. For those who want to travel for a short time, it is best to use a power bank of 5000mAh or more. Of course, the larger the capacity of the power bank, the better, the larger the volume and weight, and it is inconvenient to carry. Moreover, large-capacity mobile power supplies of ordinary quality have an impact on human safety and are not recommended for use.
3. In addition to capacity, when purchasing a mobile power supply, you must also pay attention to whether the interface matches, otherwise you will be wasting money. Different mobile phones or tablet computers have different interfaces. When purchasing a mobile power supply, you should also pay attention to choosing the interface you want.
4. Finally, pay attention to the workmanship and quality of the mobile power supply. The workmanship of a good mobile power supply is very particular, and you can see whether it is good or bad at a glance. Of course, the more important thing is its power conversion rate. Generally speaking, it is impossible to convert 100%, and the conversion rate cannot be lower than 70%.
