What is a Power Bank

Power Bank India 2016
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.

How to Use a Power Bank

Power Bank Use
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.

Types of Power Banks

power bank types 2016
Many of the power banks are device integrated and they can double or even triple the life of your battery. Power banks can also be of solar type, where you use solar power to charge the same. Basically, Power Banks are of three types: Portable charging cases, USB plug in charging banks and Solar charger.

Portable charging case:
This is a innovative piece of technology. It connects to your device like a protective case which in any case most of us use. It helps to charge the device automatically when the power is down. You just plugin the device to the charging dock when you are at home and with the case you automatically add 2-3 times the charge for your device which kicks in whenever the device battery dies.

USB plugin power banks:
These contain pocket sized little units that use an USB to connect to your device. It can be called as a secondary portable battery which charges your device when there is no electricity socket nearby. When you are near a power source, you plug it to charge the power bank, and when you go out you will have a secondary battery in hand.

Solar charger:
It is very useful when you are going out for camping, hiking, or on a trip etc. It can be used for any USB device and hence can be used for your phone, tablet etc. Having the size of a smartphone, it has a solar panel on one side. It uses sun rays to store and collect the power which can be used for charging other devices. Since it is charged using sun rays, you can easily charge the same by keeping it on the car dashboard when you are heading somewhere. The power bank gets charged so long as the sun is there, and afterwards, you can use the power bank to charge your other smart devices.

Charging a Power Bank

Power banks basically have a dedicated input socket for getting power. You can use a computer USB socket to connect to this socket for charging, but it charges faster when using a wall socket adapter. Here are a few points to keep in mind when charging a Power Bank:

  • They normally use a mini or micro USB for discharging and full sized USB sockets for charging.
  • Time taken to charge a power bank depends on its capacity and its current charge level.
  • Smaller power banks can be charged with the same time taken to charge a smartphone, but for a larger one, it can take double or triple or quadruple times the former.
  • They have an LED indicator to show the charge level, which can be used to prevent any overcharging
  • Always avoid connecting power bank to the charging source once it is fully charged, to prevent any overheating.
  • The efficiency of the power bank is calculated based on the percentage of charge transferred. When the power is getting transferred from power bank, a small portion of it gets lost due to the resistance of the power bank.
  • Efficiency ratings differ between power banks based on the type of cell used, quality of the components and environment.
  • Efficiency between 80 and 90 is the industry standard.
  • Device depletion is the state of the battery of the device which is to be charged. The lower its state, the more power is required to be transferred from power bank to bring the device back to life.

Choosing a Power bank in India

If you are convinced about the need for buying a power bank then there are some important points that you should always keep in mind. These vary from brand, capacity, portability, price and charging methods.

Trusted brands can take a lot of your tension away in terms of performance and quality of the device. A good brand will make sure to provide good quality material to its customers and if by chance there are issues will make sure to provide good customer case so that they don’t lose their customer loyalty. The trusted brands for each country vary so I won’t go into actually listing the brands but making a small research into the this aspect of the power banks will go a long way in helping you pick the right product for yourself.

In most cases more size will mean more battery backup but that would also mean most size. Most good power banks in India which average out both the requirements – capacity and size – come at around 6 inches. You can find smaller sizes if you travels are short and you need the power bank for short periods and less number of charges but if you will be away for longer period from a power socket then it makes sense to give our power bank that extra space in your pocket or bag.

The capacity of a battery is measured in terms of milli ampere hour (mAH). A 1000mAH battery should ideally charge your mobile of 1000mAH battery once fully. The voltage of the battery should be more than your phone otherwise the charging won’t happen. Also, the performance of a power bank will keep on reducing with going time as is the case with any battery. So it becomes important that you invest in a battery that will keep being useful to you in near future too.

Power indicators
You should be able to see how much juice your Power Bank contains just like you can see that in your smartphone. This will help you make sure that you are not stepping out with a power bank that itself is not charged. Having an indicator will also help you keep an eye on the power available on the power bank with you so that you know how much use you can make of your mobile before you get to a power socket.

USB Charging capability
Although now most of the Power Banks have USB port for charging purpose, but still a few older models have pin socket chargers or different sized charging sockets. And of course it is also possible that you have a phone which doesn’t have USB as a charging option and in that case you would want to make sure that the Power Bank you are buying supports the charging method of your phone. Also, though it might not be a necessity, but in case the Power Bank has multiple charging points then it would be good if it can support charge for 2 devices at least. This can come in handy actually.
