TIPS:
In the course of our sales, we found that some customers may not understand the knowledge of the battery,then gave us a bad evaluation So I would like to explain in this way:First we should know two things: voltage and current. Use the formula: power = voltage x current (Batteries of power banks are 3.7V output) Every power bank has a conversion rate. Higher end power banks possess around 90% conversion rate. Power bank conversion rate is also related to batteries used in the production. Lithium-polymer rechargeable batteries have a work output conversion rate that is generally 85% -95%, and lithium-ion (18650) battery possesses an output conversion rate between 75% - 90%. To calculate conversion rate with the real capacity and charging times you do the following: Smartphone charging is dynamic of around 500MA-1000MA with the voltage at 5V. If the battery power is marked 4000mAh, then the power of a 4000mAh power bank should be 4 * 3.7 = 14.8W, calculate by our polymer batteries conversion rate of 80%, the real total power supply for charging can be 11.8W. Take a 1500mA smart phone for example, the demand power is 3.7*1.5 = 5.55W, then it can charge the phone two times. So if you want to charge your tablet, you need a larger capacity power bank, the power bank capacity should be more than 8000MA and can provide high current 2A output charging requirements.
