Buyer’s Guide

They basically come in various sizes and designs, and there are also a lot of manufacturers in India who make power banks. Considering the various capacities and features, selecting the best option for you is a bit difficult. In this post, let me help you make a decision on the power bank that will suit you and your needs the best. Following are some points that you may need to consider before getting a power bank.

Things to consider

  • Capacity of a power bank
  • Ports in a power bank
  • Weight of the power bank
  • Build quality
  • Features
  • Price

Let me explain the above mentioned points in detail.

Capacity of a power bank

As we are talking about a 20000mah power bank, this point is not that important, but still, there are some manufacturers who mention the power bank can hold a charge of 20000mah, but the actual capacity of the battery will be lower than that. As we know, batteries are not that efficient, and they may not deliver the exact amount of capacity that is mentioned by the company.

Consider your phone is of 3000mah battery and your power bank has a storage capacity of 20000mah then the power bank should be able to charge your phone at-least 5 to 6 time. Considering this point is important before selecting a power bank for purchase.


Ports are very important in any gadget as they are the way of input and output from the device. When it comes to power bank ports play an important role in numbers and types. As we know most of the smartphones now a days comes with USB-C port so to charge a phone getting a power bank with USB-C is the best option as a USB-C port can deliver faster charging speeds. Similarly the power bank should have USB-A port just in case you have a device that has older version of USB.

USB-C in a power bank can also be used to charge a laptop that has USB-C port making it a go to option to carry with you while you are travelling.


This is an important factor for many people to consider. As the capacity of a power bank increases, the weight also is expected to increase. Some manufactures are able to tone it down with low density battery and also lighter casing but in some cases it may have a negative effect on the performance of the power bank and also life. Weight should be given minimum priority if you need a good quality power bank with high storage capacity.

Build Quality

Build quality is a factor that you may need to consider as power bank with poor build quality wont last long. Power banks made of low quality plastic gets damaged soon and also will get fully scratched when they are taken with you while you travel. A metal casing always looks premium and also can handle the bumps and hits that it will have during its life time.

Being a major factor that decides any purchase, Price is a main thing to consider. If you pay premium for a power bank that has low build quality and capacity then it wont be a good deal to have. Price should be matching the features and the capacity on offer.
