Portable power banks consist of a battery placed in a case which stores electrical energy and have a special microprocessor circuitry connected to a PCB to control the power flow. These are usually made of cylindrical lithium ion or low profile Lithium polymer. It receives power through a dedicated input socket. This power can come mainly from USB socket or a computer. It uses a mini or Micro USB sockets for charging and a full-sized USB for discharging. Even though power banks can use the same USB socket for input and output, frequent practice of the same can damage the battery.
The output has to be stepped up to 5V to be able to charge the smartphone. For the same, there is a DC-DC step up transformer inside the Power bank. The time taken to fully charge a power bank depends on its capacity and its current power level. In general, smaller units take less time (3-4 hours) to charge while high-capacity ones take around 15-18 hours. The LED indicator inside a power bank shows when they are at capacity. It also has a safety cut off in the circuitry itself to prevent overcharging, over discharging, short circuit, over current and overheating.
The life expectancy of a power bank depends on two main factors as follows:
1. The number of charging and discharging cycles it can perform reliably during its operation.
2. The time up to which the power bank can retain its charge when not in use.
The number of times a power bank will charge a device also depends on its capacity. Smaller devices will charge a smartphone, while larger capacity models can charge the same smartphone up to 5 times.

Power bank is basically an external battery in a closed case.
They have an micro USB cable at one end and the full sized USB cable at the
other end. The micro end goes into the Power bank and the other can be
connected to laptops or any other controlled power source like a DC adapter to
charge them. Irrespective of whether the USB charger is 1A or 2A, you can
connect it to either of the one as it will only take the current that it
requires. Once charged, they can be used to charge the phones, tablets etc
through the full sized USB cable; just connect the device and your power bank
and the charging starts. The progress of charging you can observe on your
device the same way you do when it is connected to a power socket.
Step:1
Connect
the cable to the mini-USB socket. A power
bank will normally have two plug sockets: one USB socket, and one mini-USB
socket. Connect the mini-USB side of the cord that came with the power bank
into the power bank. The other end of the cord should be a regular USB plug.
This regular USB plug will fit into either a USB wall adapter, or a USB plug on
a computer. Take the mini-USB port end of the cable, and plug it into the
appropriate mini-USB port on the power bank.
Step:2
Connect
the USB end of the cable to a power source. There
are two ways you can connect the USB side of the power bank cable to receive
energy. You can plug the USB into a USB wall adapter (like a typical iPhone
charger), and then plug the adapter into a wall socket, or you can plug the USB
end of the cable directly into a USB port on a laptop, desktop computer, or in
a car. Whichever way you are going to connect your power bank to energy, plug
in the USB end of the cable into your chosen power source.
·
If you plug the USB end of the cable into a wall adapter, the
adapter can be plugged into to any kind of wall socket.
·
If you plug the USB end of the cable into a laptop, desktop
computer, or car, the power bank will only charge if the power source is turned
on. That means the laptop, computer, and car all need to be running in order to
supply energy to the power bank so it can charge.
Step:3
Charge
the power bank Once the power bank is connected to some sort of power
source, an LED light should illuminate somewhere on the power bank. This LED
light indicates that the power bank is indeed receiving power and charging.
When a power bank is charging successfully the light should be a yellow or
orange color (however the charging color of the LED light may vary). Once the
power bank is fully charged, the light may go out, or change to blue or green
color. Again, this varies depending on the individual power bank. You may need
to leave the power bank to charge for several hours.
·
Typically, it may take between two to four hours to charge a
power bank from connecting it to a wall socket, and about eight hours to charge
it from a computer.
·
Often the power bank light is blue/green when it is on and is
being used, orange/yellow when it is being charged, and red when it needs to be
charged.
Step:4
Charge
your device. Once your power bank is completely charged, it is ready to
be connected to and charge a device, like a phone. Whatever charging cable you
use to normally connect your phone is going to be the same cable you use to
connect your phone to the power bank. The charging cable must be an adapter
type charger, where it is detachable from the adapter, exposing a regular USB
plug. Detach the adapter from the charging cable. Take the USB plug that was
just connected to the adapter, and inset it into the power bank. Then take the
other end of the cable (the end that plugs into your phone or other device),
and plug it into your phone. Click on the power button of the power bank, and
the power bank should instantly start charging your device.
·
If the power bank is successfully charging your device, the LED
light on the power bank should be on, and the device should show some visual
sign that it is in the process of being charged (like a lighting bolt symbol or
a plug and socket symbol).
