What is an external battery for a smartphone and why is it needed? How to use an external battery for your phone?
An article about the types and features of an external battery, its charging and recharging using a battery, smartphone.

The uninterrupted operation of modern gadgets lasts within a day, without requiring the device. However, there are cases of sudden discharge of a smartphone. In this situation, you can not do without a special charger, which is external battery.
External battery for charging a smartphone
External battery
The device is a portable multifunctional battery, which includes several components in one kit, which has a USB - input for connecting the gadget.
There are several types of batteries that differ in the number and capacity of batteries, the number of entrances for recharging, configuration, design solutions and others.
Varieties of the device
- lithium-ion batteries
- lithium-polymer batteries
The data of the device are characterized by a minimum current, a large specific container, measured in milliamps per hour, excellent technical parameters.
To select an external battery, you should look at its capacitive characteristics attached to the operating instructions.
For charging smartphones, batteries with a capacity of 2000 milliamps per hour are more suitable, for tablets, models with a capacity of 5000 milliamps per hour.
Battery options
- large capacity batteries (from 10500 - 13,500 milliamps per hour)
- compact batteries of small capacity (up to 5000 milliamps per hour)
- batteries with a design in the form of a smartphone cover
The main criteria for choosing batteries
- charging current provided by an external battery. The average current value should be from 0.5 to 2 amperes.
- marking of the charger. The current of the smartphone for marking and the current of the charger battery should be in the same numerical value or the current of the charger is larger.
- batteries with several USB outputs.
- batteries with solar nutrition elements.
Given the listed criteria, you can choose an external battery that is most suitable for a personal smartphone.
Recharge of an external battery
For recharging, you need to do the following actions:
- attach one end of the battery cable to the micro USB input
Cable accession to micro USB input
- connect the other end cable to the conventional USB power source (computer, laptop, USB input of the car).
Joining the second end of the cable to the power source
You can do this in two ways:
- through a USB -adapter connected to a conventional outlet of 220 V.
- through connection to the included (working) USB - the entrance of a car, a stationary computer, a tablet.
- bell the external battery, focusing on the changing color of the LED. Yellow color is the beginning of recharging. Green or blue color ending.
Charge the battery, focusing on the color of the LED color
- charge your mobile device (smartphone).
Connect a smartphone to a charged battery
Charging a mobile device (smartphone)
This requires a cable, one end of which is suitable for a USB device connector, and the other end suitable for entering the smartphone (micro USB-slot). Next, we take the following steps:
- disconnect the battery from charging by attaching it to your phone.
- turn on the external battery to power your mobile device.
- take a message about the completion of the charging process on the smartphone.
After the end of the recharge process, focus on the LED bulb.
The power source itself can be charged from any electric current outlet. We remember that charging an external battery is possible only if the power source is turned on (car, laptop, computer).
Charging the battery from the USB device lasts from 2 to 4 hours. Charging the battery from the USB input of a stationary computer up to 8 hours.
Small advice
Do not use simultaneous recharging the battery and smartphone. This leads to a reduction in the life of the battery.
