How many times can I charge my device?

To find out the number of times that a power bank can charge your device, you need to know:

  • The capacity of the power bank
  • The capacity of your device battery - You can find this by doing some basic googling

Let’s say you have Redmi Note 4. And you found the battery capacity to be 4000 mAh. Then a power bank of 10000 mAh can charge your phone around two times. Here’s the formula:

(80% * capacity of the power bank)/capacity of your phone battery

This 80% is the conversion losses which are inevitable. So you must account for that when figuring out how many times a power bank can charge your device. Keep in mind that as you increase the capacity of the power bank the weight of the power bank will most circumstances increase proportionately.

The process we followed

Our analysis is based on the capacity of the power banks, mAh, output, build and design, and the price (as available on To make sure that our recommended products are, indeed, the ones that deliver everything that they promise, our research analysts follow a carefully charted process.

To begin with, we brought together all the power banks available on Amazon and Flipkart. We had a list of over 250 power banks. We then designed and ran an algorithm to sort them based on the number of reviews they had received, the ratings that buyers had given, and their popularity quotient.

From this thoroughly sorted list, our researchers went through and understood every nuance of the product and selected the best of the best. Our process included pouring over amazon reviews and reading third party articles looking for anything negative mentioned about the product. 

Useful Information and tips for power banks

In this section of our article, we break down all the difficult terms for you and help you in understanding the mechanisms of power banks, which would help you compare the different features of different power banks, to know which one suits you the best.

  1. In many reviews and descriptions of power banks, you will often find this mentioned in their content: “...has an output of 5V/1A” or “...has an output of 5V/2A”. Sit back and don’t get confused. There are two elements to this. The first is the voltage specification (5V). The power bank and smartphone must have the same voltage specification. For instance, if you buy a power bank of 5V and your phone battery is of 3V or 4V, then your phone would start heating up. Nowadays, most smartphones have a 5V specification, so this will most probably not be a problem for you.
  2. The second element is the current (2A). This directly affects the speed at which your phone will charge. For example, if you charge your phone of 2A with a power bank of 1A, it will charge very slowly as the phone can not draw more than 1A from the powerbank. On the contrary, if you charge your phone of 1A with a power bank of 2A, it will charge perfectly well as the phone will take in just the required current, which is 1A, which is what is required. Hence, do consider the current rate of your device and the power bank while buying a power bank. The current rating of the power bank must be higher or equal to that of the battery of your device that will be charged.
  3. The actual capacity of the power banks is generally lower than the marked capacity, which is a known phenomenon and you do not need to worry about it. The power banks do not produce as much output as printed in the catalogue either. The output is generally lower due to some conversion losses which arise from AC to DC conversion, generation of heat, etc.The two most common cell types found in power banks are Lithium-ion and Lithium-Polymer. The Lithium-ion cells are generally cheaper and limited in mAh capacity. While the Lithium-Polymer cells are larger and don’t suffer from a memory effect over time, thus being superior to the Lithium-ion cells.
  4. Batteries have the tendency to explode, and hence it is advisable to buy a power bank from a well known company than to buy one which you might have never heard of just to save a few bucks.
  5. Qualcomm Quick Charge is a popular function of the power bank. Power banks equipped with Qualcomm Quick Charge take less time to charge itself and charges compatible devices much faster too.
  6. When we mention that a power bank can charge a device for 2+ times it means, it can fully charge it from 0 to 100% 2+ times while the device is not being used. Using the device while charging it will draw more power effectively reducing the number of times it can charge that device.
  7. LED torch of power banks are of low quality (low light emittance). In most cases your smartphone’s LED flash will be better.
  8. We chose Redmi Note 4 & S7/S8 devices to show number of times it can be charged because most devices nowadays have 3000 or 4000 mAh battery. Result will remain same for different devices having similar capacities.

Downside to our top picks

The only downside to the Mi 20,000 maH and the Adata that we could find was that it was too bulky to carry around. But then however, this is expected given the wide range of its features.

The reasons why the remaining power banks were not chosen

So in following our process we came across many other great contenders for the top 3 spots but they did not convince us enough to make it to the top three. Here is a summary of the remaining shortlisted 15, and for some of these, we would recommend you to think twice before sealing the deal:

Asus Zen Power Bank - 10050mAh: It has a great brand name, is very light and compact but we found it to be too pricey for its capacity. With only a capacity of 10050 mAh, a price tag of Rs. 1799 was way too much. Also, it had only one USB port.

Anker PowerCore Speed 10000 QC (10000mAh): The Anker PowerCore Speed power bank is very compact and light for a 10000mAh power bank. It supports Qualcomm Quick Charge 3.0 power delivery. Hence, it is the cheapest power bank with QC 3.0 support from a decent brand. This power bank combines three distinct fast-charging technologies to ensure that any and all devices are charged in the shortest time possible. Its Superior Safety Surge protection, short circuit prevention, temperature control, and other advanced safety features keep you and your devices safe. It also comes with a warranty of 18 months.

We didn’t choose this as, it is quite costly for a 10000mAh power bank, priced at ₹ 2,375. It has only 1 USB port, which means you can charge only 1 device at a time. Apart from the cost which is expected, a QC 3.0 support from a reliable brand is not a deal to overlook. After all, a power bank is a functional device and not a device to show off. And it has been known to function impressively, securing the 4th place in the list

Lenovo PA13000 Power Bank (13000mAh): Lenovo PA13000 power bank has got good brand value with a capacity of 13000mAh. It has good capacity for its price, which has been fixed at ₹ 1,299. This power bank has two USB ports, which means that you can charge two devices at the same time. It also comes with a warranty of 1 year. However, some Amazon users have complained about getting a fake power bank delivered on ordering it. This has led to several 1 star reviews.

Romoss Power Bank - 10000mAh: This power bank is less thick compared to most 10000mAh power banks. It is light in weight and is very economical, priced at just ₹ 899. It comes with 2 USB ports, which means you can charge two devices at the same time. It has the auto switch off feature which shuts down the device once charging is complete. One of the biggest drawbacks of this power bank is that it suffers from the issues of questionable brand value and support.

Coolnut Solar Power Bank - 13000mAh: As evident by its name, the Coolnut Solar Power Bank is a unique environment friendly power bank, which has a solar panel for charging. Priced at just ₹ 1,499, this is a decent cost for a power bank of 13000mAh capacity. It comes with 2 USB ports and a warranty of 1 year. It has also got an auto off feature which turns off the gadget when no device is connected.

The downside to this power bank is that although it has a solar panel as a USP, it is not practical to charge it via the sun. It is quite bulky. The brand value is questionable. The brand value matters largely when it comes to gadgets and devices like these, which is the reason why this power bank has not made it to the top our list. It is simply not wise to spend such money on questionable products when there are better products with better brands and prices available. And if you really wish to take such a risk with your money, the Lenovo power bank would be a better call of judgement. Check out this graph below showing the popularity of the Coolnut brand in comparison to it competition.

Coolnut Power Bank – 20000mAh: The Coolnut Power Bank has a capacity of 20000mAh. It has got 3 USB ports which enables you to charge three devices at a time. It has an LED display to display the remaining charge. It comes with a 1 year warranty. This power bank has a stylish design with smooth curves which gives it a beautiful look. It is also very comfortable to hold. The problem with this one is that the Coolnut Power Bank supports only 5V/1A input. The brand value and after sale services are very questionable. It is also very bulky.

F-Eye Power Bank: This power bank comes with 2 USB ports, which means you can charge two devices at the same time. It is very stylish and easily portable. It has smart 4-LED indicators which keep you updated about the remaining charge. It has got a capacity of 10400mAh. This power bank is from a company which many people have might not even heard of. Hence, it has a very weak brand value and support.

PNY BE-520 Power Bank (5200mAh): The only advantages to this power bank’s credit is that it is very light and compact and has got a built-in LED torch to ensure there is light when needed. This power bank comes with only 1 USB port. The input and output supports only 5V/1A. This means that the charging time of the power bank as well as the device connected to it is very slow. It has a capacity of 5200mAh and is priced at ₹ 1,114. Clearly, it is costly for such low capacity.

COOLNUT Power Bank 13000mAh: This power bank comes with a power adapter and three different micro USB cables. It also has a small LED display to show the remaining charge. It has got two USB ports, enabling you to charge two devices at a time. Its round edges provide a comfortable body to hold. It is very stylish and compact and has a capacity of 13000mAh. But, it is overpriced at ₹ 2,499 considering the capacity. The issue of a good brand arises once more, here. It lacks the benefits of a good brand value and support, and hence, is not much popular and preferable.

Zaap Power Bank 6700mAh: This power bank is very compact, light and easily portable. It has got LED power indicators. Its special rubber coating gives additional drop/shock protection. The Zaap power bank is priced at ₹ 1,499, which is extremely overpriced considering a capacity of 6700mAh. It has got only 1 USB port. The brand Zaap does not possess a good brand value and hence is not much reliable.

Coolnut Power Bank (7800 mAh): This power bank is lightweight and compact, making it easier to carry. It has got dual USB ports, allowing you to charge two devices at a time. It features LED indicators to show remaining charge, is durable and beautiful. It is equipped with an LED flashlight for dark conditions and features charging-discharging protection mechanism to ensure that battery life works efficiently without any issues. It is highly overpriced, at ₹ 1,199, given its capacity of 7800mAh. There arises a question of reliability as this company does not hold a good brand value. The ratings regarding this power bank aren’t that many either.

MOERDON Power Bank 10000mAh: This power bank has got 3 USB ports. It has 4 LED indicators to show the remaining charge and comes with an LED lamp function. The question of brand value arises here as well, which is a major drawback. The ratings of this power bank are not good either.

Intex IT-PB11K Power Bank 11000mAh: This power bank comes with 3 USB ports. It has a capacity of 11000 mAh and comes with a built-in torch. It is a little bulky to carry. There are also many reviews on Amazon by users who claim that the device stopped working after a few months.

Ambrane P-1310 Power Bank (13000mAh): Priced at ₹ 949, this power bank provides a good value for money for 13000mAh capacity. It is sleek, compact and easy to operate. It comes with two USB ports to enable charging two devices at a time. It also has a torch. But, it is quite bulky to carry around. This power bank failed to be selected among our top picks as there are better options available, like the ADATA power bank or the Lenovo one for 13,000 mAh where you would actually save a few bucks.

So, this was our full fledged analysis of the various power banks available in the market. We did intensive research and shared our findings with you along with our best picks.
