Buyers Guide to Buy the Best Power Bank 2019 in India

Your decision to buy a power bank gets you many experts to suggest which one is better than the other. However, it is not advisable to buy a product from someone’s point of view. The decision regarding purchase a device should go through a thorough check of the list of features and pros and cons of the product by yourself. It should be determined against the set of facts and your needs of the features. One should pay attention to technical details and compare the same with their list of requirements in priority before the decision making.

Not every device comes with every feature they could have, and it is not recommended to expect so. Therefore, let’s see what a power bank must have to fall under the list a user must consider buying.

Technicalities associated with a power bank:

The capacity of Power Bank

The charging capacity of a power bank is denoted in mAh that is milliampere-hour. Milliampere-hour is 1000th of an ampere-hour. It states the steady current flow in a device in an hour and current flow from a power bank to the other equipment like a cellphone in case of a power bank.

So, to charge a cellphone of 3000 mAh battery, you need a power bank of equivalent or higher mAh power to charge efficiently. Cellphones range from 2500 mAh to 5000 mAh battery, and power bank of equivalent mAh or more mAh is required. To charge your device multiple times or to charge numerous devices, you need extra mAh capacity in your power bank. Power banks loose charge in the process of charging itself and other devices, therefore it is advised to consider its mAh capacity a little lower than declared to get to a fairer conclusion.


Power banks are mainly available in two types of cells, one is Lithium-ion, and the other is lithium polymer. Both the battery types have their pros and cons and suit different sets of users. The Lithium-ion batteries have a higher energy density ratio as compared to Lithium polymer batteries, which means more storage of current in less mass.

The Lithium polymer batteries are new and advanced as compared to Lithium-ion batteries. Polymer batteries are lighter and easily moldable as compared to ion batteries which facilitate lightweight and slimmer batteries. They are also safer than ion batteries which face the risk of bursting through overcharging and heating. The polymer batteries have expensive manufacturing cost, and the ion batteries have comparatively lesser making them economical.

Input and Output Charge

Power bank for smartphones and other USB compatible devices come with a USB output and micro USB input. Power banks have output USB ports ranging from one to three, and some modern power banks have Type C input along with micro USB. Multiple USB ports offer convenience to charge various devices together, and multiple input charge option provides convenience to different cable user and compliance with upgrades.

Ampere Charge

The ampere charge is the current output of the power bank, which determines the speed of charging of the device through it. Ampere charge speed of a power bank ranges from 1 to 2.4 Ampere, and some high-end power banks offer fast charging through increased ampere charge up to 3.4 amperes. Fast charging works through compatibility of both the devices, receiving and supplying current. The fast charging is possible through increased voltage supply and ampere increasing efficiency to entertain fast charging.


Power banks are a lot cheaper now with increasing competition. However, mAh variants and build of the battery of the power bank bring much change in the price. It is still easy to obtain the right power bank at a low cost. There is no need to pay extra, and for the same, our list of products above features some outstanding options at a much-discounted price. So, make most of the price you pay for your power bank.

Charge indicator

The charge indicator in a power bank is a significantly important feature which many power banks lack. The charge indicator helps you keep a check on the charging of the power bank and charging you can expect from it. The indicator allows the user to keep their power banks charged for the times of use. When the power banks lack the indicator, it becomes hard to keep track of its charging, and the user sometimes ends up with no charge back up. So, always make sure your purchase of a power bank has a charge indicator.

Frequently Asked Questions (FAQs)

1. What does the mAh capacity mean?

mAh of a power bank is the energy capacity of the battery. Which means higher the mAh capacity, higher will be charging provided. It refers to the amount of charge your power banks’ battery can hold to charge other devices. mAh capacity applies to all portable batteries. To charge a mobile phone of 3000 to 4000 mAh, for example, you will need a power bank of the equivalent or higher mAh power. For technical details on mAh, kindly refer to the buyer’s guide above.

2. Which is the best power bank?

The power bank with mAh capacity 3 to 4 times higher than of your device, to be charged multiple times will be the best power bank for you. Along with mAh capacity, features like charge retention, good battery, compact size, and weight makes your purchase the best purchase. It will be unfair to list any product as the best product because choices in technical devices are subjective and highly user-oriented. Therefore, look for products according to your needs.

3. How do I choose a good power bank?

One can choose a good power bank by keeping the following details in mind:-

  • High-quality battery
  • Higher mAh capacity
  • High capacity input and output
  • Compatibility of Input and output voltage with your device
  • Quality build and sturdy material
  • Multiple ports are always an advantage

4. Can I bring a power bank on a plane?

Power banks are allowed in handbags on a plane. They cannot be kept in checked luggage. To carry a power bank or other such devices with portable batteries up to 100Wh requires no permission. Otherwise, approval is required. A 100Wh is somewhere equivalent to 20000 mAh, so power banks beyond 20000 mAh may require prior permission to carry.

5. Are power banks safe?

Yes, power banks are safe for use unless any malfunction or defect which leads to lithium-ion batteries exploding. A check on the charging and life of the battery can help in avoiding such a situation. Modern power banks, even with lithium-ion batteries, have temperature resistant chipset with layers of protection. The other lithium polymer batteries are entirely safe for use as they possess no risk of exploding like ion batteries. Therefore, safety can be assured by buying quality products and maintaining them properly.

6. What is the price of a power bank in India?

A power bank in India can be bought in a few hundred to some thousands of rupees. Typically a power bank with low mAh capacity can cost you 500 to 800 rupees and can range up to 15,000 to 18,000 rupees. The price of the power bank depends upon the mAh power, battery quality, and the number of ports.

7. How long do power banks last?

Power banks have a life of charge cycles. They last to the number of times they have been charged and discharged like 500 charge cycles for the right quality power bank. This means your power bank with 500 charge cycle of life will effectively charge for 500 times, which is 500 times it exhausts its battery backup to charge your phone. Power banks with lithium polymer batteries last longer as compared to lithium-ion batteries which ages even when not in use. So, your power bank with a life of 500 or more charge cycles can work efficiently for 18 to 24 months.

8. Do power banks damage battery?

Power banks of good quality with compatible charge output of your phone will not damage your phone’s battery. However, the power banks with uneven charge output and wrong charge output against the capacity of your phone can cause damage to the phone’s battery. An incorrect voltage output can cause severe damage to your mobile phone. Therefore, be skeptical about buying a power bank. Keep the emphasis on buying a good quality, compatible and right voltage emitting power bank.

9. Can a power bank charge itself?

Technically no. A power bank cannot charge itself. Plugging a power bank to itself will do nothing as to charge, a device needs higher voltage to charge other devices. Also, doing this will result in losing the charge of your power bank and damaging the battery of the power bank.

10. Is 10000 mAh power bank enough?

A power bank of 10000 mAh is enough for a phone battery of 3000 to 5000 mAh to charge once or twice. You can charge the phone of less mAh multiple times with a 10000 mAh power bank.
