Specifications:

- Capacity is 5000 mAh , - C harge and discharge cycle times or 600 times- 2.1 A MAX input DC5V. (Micro USB port)- Size: 142*65*11mm- Certification of the FCC \ CE- Protection circuit- Conversion rate of about 85%- USB1: DC5V 2.1A, USB2: DC5V 1.0A- Weight about 142g-Charging time about 3.5hoursSupport for mobile phones, tablets, MP3, MP4 and other digital products 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 evaluationSo 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.If you have any questions, please contact our customer service , we will reply to you as soon as possible. 1 * Romoss Polymos05 5 000mAh Power Bank. 1 * USB Cable. 1 * User Manual
