Is it 30000mAh?20000mAh?

This is a standard 3.7V / 30000mAh power bank, the general debt output voltage is 5V, so the actual power you use is 3.7V * 30000mAh / 5V * 95% (electricity conversion rate) = 21090mAh, if your mobile phone battery is 3000mAh , Then the charger can be fully charged at least 7times.

How to identify the quality of general power bank?

1. Charging treasure has two kinds of batteries, 18650 and lithium polymer batteries. 18650 batteries are like large-sized dry batteries. They have large capacity and small size, but have poor safety and poor quality. The life time period, the number of charge and discharge between 100-300 times. Lithium polymer battery is directly proportional to its capacity and volume, and its safety is very good, discharge between more than 500times. It is generally used in charging treasures above 20000mAh. Lithium polymer batteries also have different grades , which are divided into A, B, C and other grades. Our power bank uses Grade A battery (can accept professional test).

2. The main board of the power bank (electronic component board), the quality of the electronic chip will affect the speed of charging and discharging. We use a self-developed chip that can automatically adjust the current supplied according to the size of the load to protect the load and the power of the power bank itself (The charging speed is also related to the charging cable and the load).

3. The weight of the real power bank is stable within a certain range. The weight of the real 10000 mAh power bank is about 200g-250g, the 20,000mAn power bank is between 450g-520g, and the 30,000ma power bank is between 640g-710g.. In order to deceive buyers, some bad businesses will fill lead blocks or cement blocks inside the charger (I have bought fakes with lead blocks inside), so when you buy the charger, you can measure the weight of the charger .

4. The above rules only apply to general chargers, graphene chargers, and polymer chargers. Different chargers have different performances, which can be judged by other users’ evaluations (professional test evaluation).
