Mobile power bank is a common and universal high-capacity battery for charging handheld devices. In our daily use, we need a few simple 

techniques to let the Power Banks fully play their roles to provide reliable power support for 

our mobile phones, MP4, tablets and other equipment.

The main internal components of power bank is lithium battery and circuit board, so we need to use them in a correct way in order to extend 

their life spans. There are power banks with different function designs in the market, therefore, there are also some differences on how we 

use them.

Switch Button on Power Banks

The vast majority of mobile powers currently in the market have one power button on the shell. This seemingly simple button usually has three 

functions, that is, power switch, electricity quantity display and flashlight switch. In order to let users use the power bank more 

conveniently, some power bank manufacturers even adopt auto-detect circuit design. For most power banks, we can turn on and off the power by 

a short press on the button, see the electricity quantity by two times’ press on the button and turn on and off the flashlight by a long 

press of 2-5 seconds on the button. power control and flashlight function.

Don’t Charge the Device Until Its Power is Over

For lithium battery, its output power varies in the discharge process because of different current. Usually the output power will be smaller 

when discharge under heavy current.

When the charged lithium battery capacity in the device is low, power bank will charge it with a higher current, like 5V/1A. Along with the 

capacity in the device gradually increasing, the power bank output power will decrease from 5V/1A to 5V/0.7A.

Mobile power bank will generate more heat when it is full load. Therefore, it 

is better to use the power bank to charge the devices with small current, that is, to charge the devices when there is still some electricity 

remained and the device is idle. In this way, we can reduce waste of electricity, and reduce more heat generation of the power bank itself.

Pick Suitable Charging Speed

Many consumers will see parameters like 5V/1A or 5V/2.1A when selecting power banks. In the eyes of most people, buying a power bank with 

output capacity of 5V/2.1A seems to having a faster charging speed. However, the charging current is determined by the charged device. That 

is to say, if we use a power bank with output of 5V/2.1A to charge a device with input of 5V/1A, the charging speed with not be faster than 

the power bank with output of 5V/1A.
