With smartphones becoming more and more powerful, the one thing that you need to know is that they are also getting more power-hungry. While companies making the chipsets of these smartphones are trying their best to keep them power efficient, something always comes in the way. For instance, the Galaxy S8 and Galaxy S9 are nearly identical except the processor, but the S9 drains more battery. In a situation like this, having the best portable charger is a huge blessing. Especially if you are someone who spends a lot of time outside the house. Portable chargers  are available in a surplus in the market. Meaning that you are never running out of options.

Finding the right one should not be an issue; as there are not a lot of things that you need to keep in mind. Still, to make the buying process transition easily without any issue, there is a buying guide available at the end of this article.

For now, let us go ahead and look at all the top portable chargers/power bank options available in the market.

How to Buy The Best Portable Charger

If you are in the market looking for a good power bank/portable battery charger. You might have trouble finding the best possible option. However, if you are always out and about, then having the right portable battery charger is important, because you really do not want to run out of battery in the middle of commuting from one place to another, or while flying long flights.

Now buying the right portable charger is not all that difficult. However, due to just how saturated the market is, the process can certainly be a difficult one. In order to find the right power bank for yourself, there are a few things that you need to go over.

This buying guide is great for people who are looking for an easier experience buying the best possible power bank in the market. We are going to discuss all the facets that you should be keeping in mind.

The Capacity

The first and perhaps the most important thing that you need to consider when buying a power bank is the capacity. Just like the batteries in your smartphones, or laptops, the power bank batteries are also represented with mAh. You can get as low as 3,000-mAh power bank, and go as high as 30,000 and beyond.

However, the important thing that you need to know here is that the higher the capacity you go for, the longer it will take the power bank to charge.

The Size

Power banks come in all shapes and sizes. So, this is definitely the one important thing that needs to be considered. The bigger capacity you go for, the bigger the power bank is going to be in the size. However, some great models we reviewed manage to keep a slim profile, and still provide a high battery capacity.

The Device You Are Going to Use It With

People normally skip this entirely, but when you are looking for a power bank, definitely consider the device you are going to use it with. For instance, if you own a Samsung Galaxy S9, then you are going to need to get a power bank with larger capacity, and not just that, you are also going to need a power bank with USB Type-C support.

The Number of Devices You Own

Another important thing that you need to consider is the number of devices that you own. There are power banks that are specifically built for phones. However, there are power banks that have multiple purposes. For instance, we reviewed a power bank that can charge phones, DSLR cameras, as well as laptops.

Of course, these chargers are going to be on the more expensive side of things, and they will be heavier to carry as well. Still, having an all-in-one, universal power bank is a great benefit that one cannot simply ignore.

The Required Charging Time

Power banks charge slower than smartphones because of the amount of battery capacity they hold. There is no rocket science behind that. However, some of the top tier power banks come with quick charge features as long as you are using the supported quick charger.

Additionally, most chargers that have a USB Type-C input charge faster than a standard, micro USB power bank. You will be paying a higher cost for a USB Type-C power bank but the biggest benefit is that you will not have to wait really long for your power bank to charge.

Additional Features

Once you have decided all of the above, you can start looking at some of the additional features. The reason why I am using “additional features” as a heading is because most of these features are novelties that are included in a power bank.

Most power banks in the market come with a display; it is mostly a small OLED. Now the cheaper ones only display the battery percentage of the power bank itself. However, there are some higher end options available in the market as well. These OLED panels display things such as the battery level, as well as the heat, along with some other details about the power that is being delivered to the device.

Another novelty feature that a lot of people love is the combination of a built-in power cable along with interchangeable tips for different devices. Such power banks are getting more and more common in the market, and are great for people who do not like carrying separate cables with them all the time.

Another great feature that more and more power banks are coming with is the feature of wireless charging. I know it might sound like something that is a waste of money, but some people actually prefer charging their phones wirelessly, because that is so much hassle free as compared to lugging around a wire with you at all times. This kind of power bank is surely more expensive, but the good thing is that it always support both cable and wireless charging so you do not have to worry.

Last but not the least, having a power bank that is compliant with Qualcomm’s QuickCharge technology is always good. Not only it allows you to charge your phone faster, but it is also great because it will work on every phone as long as the phone comes with the support. A Power bank with QC 2.0 or 3.0 is not that expensive as compared to the standard power bank, and at times, there is no difference in the price.
