What is Power Bank? How to Choose Right Power bank For Mobile?

Nowadays we use our smartphones too much. We have to charge them twice or thrice a day. From accessing the internet to listening to music, everything is done on smartphones. But the irony is that we have limited power. Usually, in 5 to 6 hours of continuous use, mobile battery drains to 0%. Then we have to look for the power source to charge the mobile battery. In most cases, we can not find a power socket. That’s why we need a portable power supply. I hope that now you got the answer to, what is a power bank?

If we look online for power banks, we will get plenty of them. So the question arises, How to Choose the best power bank for mobile? 2 years back when I was looking for a power bank, I got confused with so many power banks. Eventually, I choose one, but that was not the best one.


After that, I came across a lot of power banks and used them whenever I got the chance. They all have nearly the same configuration and price. I have also shortlisted the five best power banks under 1500 Rs. This article will help you to choose the best power bank for your smartphone and tablet.

What is Power Bank?

The power bank is nothing but a big battery placed in a shell. In simple words, we can compare the power bank with an inverter and battery. The power bank comes in various battery sizes ranging from 2000 mah to 12000 mah. Some companies offer more than that, but the standard size is 10000 mah for mobiles.

Initially, we have to charge the power bank and then we use this power to recharge our mobile and tablet battery. The power bank has an intelligent circuit that maintains the whole process. You have to connect your phone to a power bank using a data cable.

How to choose the best Power Bank?

Everybody wants to buy the best available power bank in his budget. So we will tell you the factors that you should consider while choosing a power bank online.

1) Power Bank Price

The very first thing that you should look for is the power bank price. Why pay more, when you are getting the same quality and configuration at a low price.

In most cases, you can get power banks at a low price as compared to the local market. Moreover, you don’t have to waste your time in the market

2) Power Bank Battery Size

The battery is the heart of the power bank. Check the battery size of all the power banks available in the budget. What is the battery size of the power bank that you are going to need? Usually, battery size is indicated in mah ( mili ampere hour). More it is more powerful will be the power bank. For example, Intex 11000 mah power bank comes with an 11000 mah battery.

Typically people prefer 10000 mah power banks. A 10000 mah power bank can charge a mobile with a 2500 mah battery three times. If your requirement is only to charge 1 or 2 times, then you can even consider 5000 mah power banks.

3) No of USB Ports for Charging

Some power banks have 1 USB port, some have 2, a few have 3. Before choosing any power bank, you should check your requirements. If you are the only one, who will charge mobile. Then 1 USB port is enough for you. But if you have to charge 2 or more devices simultaneously then you may consider two ports.

4) Power Bank Efficiency 

You must check what is the efficiency of the power bank that you have shortlisted. Good quality power banks have around 80 to 90% efficiency.

For those who don’t know what is efficiency. Let’s understand efficiency in a simpler way. Suppose you buy a power bank with a 10000 mah battery. Now if you think that this power bank will give you 10000 mah useful output power, then you are wrong. In power banks, some power gets lost in the form of heat due to circuit resistance.

If the above power bank has 80% efficiency, then you will get around 8000 mah useful output power. So higher is the efficiency better it is.

5) Power Bank Charging Speed 

Nobody likes slow charging. Slow charging is suitable for the mobile battery. But who has the time to wait for mobile charging? So check the USB port output rating. 1 to 1.5 A current is enough for small mobiles. But for tablets and high-end devices, you should choose the power bank with more than 2 A output current. If your device has more than 2200 mah battery, then you should choose the model which has more than 2 A output current.

The above paragraph is about mobile charging using a power bank. Now coming to the power bank charging. A good quality power bank with 10000 mah battery takes around 8 hours to charge fully. Though charging rate also depends upon the charger, you are using to charge it. Nowadays big brands like Moto, Asus is giving turbochargers with their handsets. Turbochargers can charge a 10000 mah power bank in 5 to 6 hours.

6) Brand Value and Customer Support

Brand value is the quality level of the brand. No of people using their products reflects the brand value. If a company has good brand value then it is obvious it would have good customer support. You should look at whether the company has a service center near your location. If yes, then what is the service standard it offers to its customers.


7) Ask the Experienced Person

Configuration written on paper is not the final thing. Built quality and brand value also matter a lot. You can not find out the build quality of a power bank just by seeing its configuration. A person who has some power banks can tell you about user experience.

You can ask friends and relatives. You can even ask us. We will reply to you back with the best power bank for you at the cheapest price.
