How to Choose a Power Bank in India – Buying guide

These are some of the most important features to look into when you are looking for a reliable power bank

Charging capacity

Battery Charging Capacity

This is the amount of “energy” a power bank can store. Most power banks today have between 10000mAh and 20000mAh capacity.

If you might find yourself lost in these numbers, you can also look at what the manufacturer says about the number of charges.

“How many times can you charge an iPhone X using the power bank?” might be a good hallmark. So, look for this information if there is any.

If not, you can keep in mind that usually, a 10000mAh battery can fully charge an iPhone 10 two or three times.



A 10000mAh power bank might look like and sound like a lot, but you’ve got to keep in mind that smartphones have got really big and powerful lately and also their battery capacities have expanded with that.

So, first of all, you need to compare your smartphone’s battery capacity with the power bank’s capacity and then you need to consider that the real capacity of a 10000mAh is not 10000, but less.

So, let’s say you’ve got a smartphone with a battery of about 2000mAh and a power bank of 10000mAh. Logic says that you could charge your phones 5 times using the power bank, but in reality, you can charge it 3 times at most. This is much like a rule of thumb that you need to keep in mind. So, a good quality 10000mAh battery will actually have about 6000mAh in it.

This difference does not come from the manufacturer’s bad intentions of tricking you; it’s got a technical explanation. You cannot really measure a battery’s capacity in mAh when different voltages come into play.

Usually, a power bank comes with a li-ion battery which can output 3.7 volts, while your phone’s battery can be charged at 5 volts. So, a 3.7 volt, 10000mAh power bank capacity when used at 5 volts, is about 7400mAh. In addition to this, you might also consider the loss of energy resulted from the conversion process from 3.7 to 5 volt and you’ve got a little less energy in power bank in the end.

The bottom line here is: also look at the power bank’s voltage, not only amperage before deciding on a certain power bank.

Charging speed

Smartphones today come with fast charging. This is a very useful feature since we’re so dependant on our mobile devices, that we cannot be without them.

Fast charging means you can charge your smartphone battery from 2% to 50% in about 30 minutes. With most power banks you cannot do that, but there are also some which support quick charge. So, if you’re looking for quick charging speeds for your smartphone, then this is also a feature to take into account.

Also, it is important to check the charging speed of your actual power bank. Usually, this depends on its capacity. The bigger the power bank’s capacity, the bigger the charging time. It also depends on its built and technology.

So, if you know you travel a lot and don’t have much time to charge both your smartphone and power bank, then the charging speed should also be an important spec on your list.

Number of ports/ Connectivity

Power Bank Ports

Today we live in the era of USB Type C ports, so buying a power bank with at least one Type-C USB can be a really important asset, since it can charge in both directions and also support fast charging. Nevertheless, it’s not a must, you can survive without one, also.

One key aspect, though, is the number of ports. If you know you’ll need to charge more than one device at the same time, then you should look in the direction of power banks which come with 2 or more ports and which support dual charging or even better, charging three devices at the same time.

Usually, power banks come with a USB adaptor for charging, but others might come with more than one or none. Also, pay attention to this detail as you might want to know what you’re actually buying, the value you get for that sum of money.

Size, weight, and design

Usually, the size and weight of a power bank depending on its capacity and technology used. The bigger the capacity, the bigger the size of the power bank.

It’s normal, right? So, if you’re looking for a pocket-size power bank to keep with you in case of emergency while you’re partying all night long at a music festival or spending a whole day at a picnic, then it’s ok to compromise capacity for reduced size and go for a 10,000mAh product.

If you’re looking for a “life-savior” during long work trips and traveling, then you will have to sacrifice a compact design for bigger capacity. These are the options right now on the market.

Other optional features

Fast charging is currently more of an optional feature on power banks. For a fast charging feature, you need a compatible power bank and cable.

Some power banks come with additional safety features such as protection against over-heat, over-charge, over-current, over-discharge and short-circuit protection. It would be nice to buy a power bank that has one of this security protection as well.

Another optional feature on power banks is a power indicator. Most power banks come with one or three light bars which show approximately the energy you have left in your battery.

However, there are some devices that provide you with a more clear indicator of power, like a mini LED screen with a battery percentage. This would be a nice touch, but not a must.

There are also some power banks that can be taken on rough terrain, like mountain trips and can recharge themselves using the sunlight. If you’re a mountain enthusiast, you might want to look into these features as well.

Nevertheless, there is a completely different power category here, so let’s stick to the more normal-looking power banks out there and go through some frequently asked questions.

FAQ about Power Banks

How long do power banks last?

It depends on a lot of factors, like the quality of the battery cells or the controller circuitry. It also depends on how it was used and the level of care you’ve invested in it.

Usually, the average life of a power bank is 3 years. If you really care about your power bank, there are a few rules you should consider in order for it to last more. Try to avoid using the device in extreme temperatures and make sure all the devices you charge are compatible with the power bank.

Moreover, don’t let your power bank go completely empty before recharging it again.

Is 10000mAh enough capacity for a power bank?

A 10000mAh power bank is enough if you have an iPhone X you want to recharge in case of an emergency. As we were discussing above, capacity is not the only thing. It’s also the voltage. If your power bank has a 10000mAh capacity and functions at 3.7 volts, then charging your 5 volts iPhone X will drain more than its 2716 mAh battery.

The bottom line here is: if you only want to charge one device multiple times, then yes, a 10000mAh power bank is enough. For two or more devices, chances are you’ll be out of power in two days.

How many phones can I charge simultaneously with one power bank?

There are power banks that have more than one connector and allow you to charge 2, 3 or even 4 devices at the same time. Nevertheless, you should bear in mind that the more devices you plug in the power bank, the less the charging speed.

For example, with a fast charge power bank, if you plug in two devices, then none of them will get fast charging anymore. So, you should also consider that. But yes, it possible to charge 2, 3 or even 4 devices at the same time.

Can I charge the power bank and phone at the same time?

Well, usually batteries cannot both charge and discharge at the same time. You can try this, but the power bank battery will not charge much in the process. There are some power bank manufacturers who advertise this feature on their products; still, why would you want to charge both power bank and phone at the same time?


There are a lot of power bank types out there and there’s probably one specifically made for you. Although overall, they look the same, you should always consider “minor” features like dual charging, fast charging, LED indicator, short-circuit protection, warranty.

We’re not the same and we don’t have the same activities, hobbies or we just don’t spend the weekends in the same way. So, if you’re a mountain enthusiast, you might want to go for a big capacity power bank, with fast charging and solid build to take with you in your weekend getaways. If you’re more of a picnic or festival-kind of person, then a lightweight low-capacity power bank might be all you need.

All in all, you should decide what you want, what you need and what you like and then take into account all the above features, make the right purchase for you.
