As the usage of smartphone has increased rapidly, investing on power bank has become a necessity. Though smartphones come with high-performance battery, due to increased internet usage (thanks to JIO) for heavy browsing or live chatting, the battery seems to drain quickly.
So, if you are a person who travel long distance regularly or need your mobile to keep going on for a longer period of time then a power bank can be helpful.
While selecting a power bank, the main factor to consider is battery capacity which usually depends on your power backup requirements. A 10000mAh battery capacity power bank can charge your phone 2 – 3 times in a day while 20000mAH can charge 5 times per day. Apart from that, you have to consider No.of USB ports for multiple device charging, weight and portability for pocket friendliness and others.
Our team has done an extensive research for almost 100 hours and picked up the best power banks available in the market. You can read the factors we have considered while choosing a power bank by clicking here.

How to Choose the Best Power Bank?
We have so many brands offering power bank products in the market. But if you think all are same then you are wrong. There are some features you have to consider while choosing them.
Every one of us have a different requirement, so it is important to know the purpose of power bank before buying it. If you want to power back up for small devices like bands, smart watches and others then 10000 – 13000 mAH is more than enough. The same is also good enough for mobile or smart phones as well. Because most of the phones have 3000 – 4000 mAH of battery capacity, you can easily charge 3 – 4 times. However, if your requirement is much higher then you have to buy a power bank with 15000 – 20000 mAH. But remember that they will costlier and bigger in size.
2. Current Output
If the current output is high then you can charge your phone very fast. So, make sure the power bank you choose has PB of 2A or more. And it is also better to check whether your mobile phone is compatible to high current or not.
3. Type of Power Bank
There are three types of power banks – Portable charging, USB plug in charging, and solar charger.
- Capacity: Make sure the battery capacity of the power bank is more than your devices. The mAh of the power bank you buy should be at least twice the battery capacity of your mobile.
- Potable charging: This type of power bank helps to automatically charge the device when the power is down. You have to plug-in the device to the charging dock. They provide 2 – 3 times of full battery charging. These potable charging docks are recharged using an electrical outlet using a power adapter.
- USB Plug-In: These are portable devices that fit in our pockets. They use USB to connect to the mobile. It doesn’t need electricity socket to get charged. It is usually charged with a laptop or any other power source and you will have a secondary battery in your pocket.
- Solar Charger: This type of charger is very helpful when you go out for camping, trips, hiking or where you cannot get an electric power source. Its size is similar to that of a smart phone with solar panels on one side. It converts power from the sun rays which can be used to charge up your phones, tablets or others.
4. Energy Efficiency
The energy efficiency of a power bank depends on the percentage of charge transferred. Usually, when a power is transferred to a device, a small amount of it gets lost due to heat and voltage conversion. No power bank is 100% efficiency and it may vary depending on quality of components used, type of cell used, and environment. Usually, a good power bank should have 80 – 90% energy efficient as per industry standards.
5. No. Of USB Ports
It is better to select a power bank with at least 2 USB ports. It helps to charge multiple devices at one time. You can even offer a port to your companion while travelling.
6. Security Features
This feature plays a very important role because some power banks can have the risk of blasting. Always choose a power bank which has protection from overcharging and overheating. Or else it can be a risk in carrying it in your pocket.
7. Size / Weight
Most of the powers banks available in India come around 6 inches. You can even find smaller one if you travel short or you need power bank for only short period battery backup. A lightweight product can be easy to carry out. Heavier and bigger ones are not handy compared to them.
8. Charging Time of the Power Bank
You have to look out for a power bank that gets fully charged quickly. Usually a good power bank with a capacity of 10000 mAH gets charged completely in 6 – 10 hours.
General Information about Power Banks:
What is a Power Bank?
Power bank is a portable charging device that consists of a battery and a circuit that controls power flow. It allows the user to store electrical energy which is later used to charge up smartphones, tablets, digital cameras, handheld gaming devices and other gadgets.
Power banks usually contain a cylindrical lithium ion or lithium polymer battery that gets power through a dedicated USB input socket. It uses mini or micro USB ports for charging other devices and a full-sized USB port for discharging.
There is a DC-DC step up transformer inside a power bank that boosts the output to 5V so that it can charge high-end smartphones.
The total time required to fully charge a power bank depends on its capacity. While power banks with low mAh take 3 to 4 hours to charge, power banks with high mAh take 10 to 15 hours to charge.
There is a LED indicator in most power banks that show the how much charge is left in the power bank. It also incorporates a safety circuit that prevents overcharging, over current, overheating and short circuit.
How to Charge a Power Bank?
- Power bank comes with a dedicated full-sized USB input socket which is used for charging the power bank.
- A computer USB socket or wall socket adapter can used to connect to this socket for charging.
- A charging cable has a mini-USB port and a full-sized USB port.
- Connect the mini USB port end of the cable to the mini-USB port of power bank and plug in the regular USB into a USB wall adapter or a USB plug on a computer.
- Once the power bank is connected to a power source, the LED light indicator should illuminate in the power bank.
- Time taken to charge a power bank depends on its capacity and its remaining charge level.
- Power banks don’t have as much efficiency as their capacity. A certain portion of the power gets lost while being transferred from the power bank to the device due to resistance of the power bank.
- Some power banks have 70 to 80% efficiency while others have 90%.
- It is best to not to keep the power bank connected to the charging source once it is completely charged in order to avoid overheating.
How to use a Power Bank?
All power banks come with a USB cord. Just plug in one end of the USB cord into the power bank and the other end into a charger wall outlet. Keep the power bank plugged into the wall outlet till it is completely charged.
Once the power bank is fully charged, you can charge other devices using it. Connect the USB male end to the power bank and the USB female end to your cell phone and notice whether the battery icon in your device starts charging.
To charge your phone battery faster you can power off your phone until the battery icon on your phone’s screen fully green. It is better to avoid using a phone while it’s connected to the power bank to prevent slow charging.
Important Parts of a Power Bank
Battery – This is the most important component of a power bank which determines its capacity. Most of the power banks use lithium ion or lithium polymer batteries. While lithium ion batteries are cheaper, they have limited mAh capacity. Lithium polymer cells are a bit expensive but they last longer.
Output USB Port/s – A power bank may have one or more USB output ports. Output ports connect to mobiles, tablets and other devices, carry power from the power bank and charge these devices. Out ports may have varying rate of power output – some supply 1Amp power others supply 2Amp power.
Input Micro USB Port – Power banks have 1 micro USB port which is used to charge the power bank.
Indicator – Most power banks have either 3 or more LED lights or a LCD power display that indicates the capacity left in the power bank.
Off Button – Most power banks have a dedicated Off-button which is used to start charging a device. It is also used as the on/off button for torch present in some power banks.
A power bank is a saviour and a reliable accessory in times of need. Needless to say, you need to hold only the best of the product.
