These are the best ultra-high capacity portable charger options if you plan to use a power bank to keep all of your fancy technology charged.

The capacity of the battery should be your primary consideration when selecting the best power bank for you. Consider how long you’ll be on the road and how many devices you’ll be carrying. Consider how power-hungry those devices are, as recharging a laptop or camera requires more power than recharging a phone or tablet.

However, a balance must be struck between power and weight, because as capacity increases, weight increases as well. It might be worth sacrificing some capacity for the added portability of a smaller power bank.

You should also make sure that the power bank you choose is compatible with the devices you intend to charge. If you plan on charging more than one device at a time, the number of charging points on the portable charger is also important to consider.

We’ve highlighted the weight, size, and battery capacity of each power bank in this list, as well as the number of charging ports, to help you see how they compare for these factors. We’ve also made sure the list includes devices that work with a variety of different manufacturers’ devices.

What Features Should You Look for in a Power Bank?

It’s stressful to watch your phone or tablet slowly drain its battery when you’re not near a power outlet. Fortunately, third-party backup batteries are plentiful, and they come in a variety of sizes, capacities, and price points to keep your device running when the battery icon starts to turn red. It doesn’t stop there. Fast charging, wireless charging, built-in cables, AC adapters, LED flashlights—and even the ability to jump-start your car—all come standard on some power banks. How do you know which which brand of power bank is best is right for you when there are so many options? Continue reading to learn about the most important considerations.

Capacity and Design

Of course, a power bank’s design is important because you may spend more time with it than you realise, and your desi friends may notice.

You should also consider its size and weight. If you want a higher mAh power bank, it will be heavier and, in some cases, more unsightly.

The capacity of a power bank can range from 3000mAh to 30,000mAh. Due to future technological advancements, you may be able to obtain a high-capacity power bank. What does mAh stand for?

The abbreviation mAh stands for milliAmpere hour. It is a measurement of the battery’s ability to store energy. You might compare it to the fuel tank in your car. You can pour more fuel into it as it grows larger. That is why a power bank’s capacity is expressed in milliamperes (mAh).

However, the ideal battery range is 5000 to 10,000mAh, which is ideal in terms of both design and performance. Depending on your battery capacity, you can charge your phone 2 to 3 times with the above range.

If you’re travelling to another city or province in Pakistan, aim for a battery capacity of 15,000 to 20,000mAh to meet your needs.

Input and Output Ports

Not only does the type of port (or ports) a battery has influence whether it is compatible with the devices you want to charge, but it also influences charging speed. Most battery packs will have a standard USB-A port for charging the battery (power input) and sending power to your device at the very least (power output). However, because the USB-C standard has been adopt by the majority of phones, tablets, and laptops, you’ll often find a USB-C port in addition to a USB-A port.

Some, but not all, fast charging protocols for smartphones and tablets are supporte by USB-C ports. Most USB-C ports are used for both power input and output, but you should double-check because some less expensive battery packs may only use USB-C for power input.

Fast Charging

Another consideration is the speed with which a power bank can charge your phone. The voltage and amperage of a battery’s output are measured. The amount of electricity flowing from the battery to the connected device is known as amperage (or current), whereas the amount of potential energy is known as voltage. Wattage, or total power, is calculated by multiplying volts by amps. Most manufacturers increase the total wattage by varying the voltage or increasing the amperage to make a device charge faster. Boosting or dynamically varying the voltage is the most common method for fast charging.


Finally, think about how much you’re willing to spend on a power bank. It will be much easier for you to decide which power bank meets your needs if you have low budget. As there are many options in the same price range.

A small and light power bank will cost around $30-$40, while a larger power bank will cost well over $100. Finally, it comes down to personal preference.


Companies frequently provide generous warranties with their products.

To protect your interests, you should choose a which brand of power bank is best that comes with a warranty. Popular brands such as Anker, Aukey, and others provide at least a one-year warranty on their products.

How we test

It takes more than connecting a power bank to a phone and charging it to see . Testing battery packs take weeks, not days, and requires specialized equipment to ensure that the batteries perform as expected.

1. Each battery pack is fully charge when it arrives, with indicator lights to track the charge level.

2. We then use an AVHzY USB Power Meter in conjunction with a DROK Micro Load Tester to track efficiency.

We can test against a battery’s stated maximum current and verify that proper shutdown. Mechanisms are in place if something goes wrong during a charging by using the DROK to drain the battery pack’s. Power, use a load tester (such as a device drawing over the maximum amps). We can monitor volts and amps, total power, total amount time to deplete battery using the AVHzY USB Power Meter. For future reference, the metre can create an Excel spreadsheet of the entire process.

3. We then charged the battery again, this time using the AVHzY to track and time take to reach full charge.

The AVHzY metre corrects a flaw in our previous method using the PortaPow. Previously, we had to track each battery through its charge cycle with a GoPro camera. Because the PortaPow monitor continued to collect data after the battery was fully charged.

We use USB-C instead of Micro-USB when a battery can be charge via USB-C.

4. The AVHzY also has a built-in feature that checks a charging port for all of the charging standards it supports. Without having compatible phones, we can run and get an instant readout to confirm support for QC 3.0.

Final Thoughts:

In the end, we give vehemently support to our views that all the above mention power banks are the best in the world. It would be crystal clear beyond any shadow of a doubt Above all the brand about of which brand of power bank is Best. So, you can choose power bank for yourself.
