  Small details that should not be ignored when buying mobile power banks

  1. Check the rated output of the mobile power supply

  Rated output includes voltage output and current output. Since different brands of mobile phones have different input voltages and currents, the rated output range of mobile power banks for mobile phones is limited. The rated output is best to match the rated input of the mobile phone used accurately, so as to protect the mobile phone from damage due to overcurrent and overvoltage. Although the larger the rated output range, the more mobile phones that can be used, and the cost-effectiveness is high. However, many mobile phone power banks blindly pursue the scope of application, often neglecting the circuit protection design, the poor technology, and the use of inferior materials, resulting in the standard output becoming a fake.

  Second, check the capacity of the mobile power supply

  Capacity is a parameter expressed in MAH (milliampere hour) or WH (watt hour), and the conversion rule between them is AH*Voltage=WH, 1AH=1000MAH. If the battery of the applicable digital device is 700MAH, the mobile power bank with a capacity of 2200MAH can be charged 2-3 times. The higher the capacity of the mobile phone's mobile power supply, the more times it can be charged. The larger the capacity, the better. First of all, the capacity of many mobile power sources seems to be very large, and most of them are false propaganda by irregular manufacturers, and the actual output cannot be reached. Secondly, security requirements are higher. It is best to choose a mobile phone power bank with a suitable capacity and issued by a regular manufacturer

  Three, check the number of uses of mobile power

  The number of times the mobile power bank can be recycled can still maintain about 80% of the power on the product box of the mobile phone power bank. The mobile power bank of Wopin mobile phone can be cycled more than 500 times, which refers to the life of the mobile power bank. The lifespan of mobile power is related to batteries. At present, except for inferior batteries, there is not much difference between different brands. The mobile power bank of the mobile phone is considered in accordance with the full charge and release twice a week, which can ensure that the effective time reaches 5 years.
