A power bank is a portable charger that can be taken anywhere and because of that, they’re growing very quickly. Most of us are used to using stationary charging electronics such as USB wall chargers and even though they use many USB charging ports and have powerful charging speeds, they can be a hassle to use because our devices have to stay in a single spot for recharging.

With that said, with the increasing popularity of power banks, there are now lots of companies that sell them and that means more innovation is being done. The result of innovation is that we now have lots of types of power banks on the market. It’s a great thing to have such a wide selection, but it can also be a bad thing because you have no idea what to select. That is why in this article I’ll be going over the main parts of a power bank to know before you purchase it.

Power Capacity and Portability

The power capacity and portability of a power bank are both connected. That’s because depending on what the power capacity of a power bank is, it may use just a single battery or many batteries. Which is why there are two main types of power banks to know.

Low Capacity

First off, the most used types of power banks are ones that have low power capacities. The reason for that is because a low power capacity means that a power bank uses a single battery most of the time. As a result, these types of power banks come in two main form factors and that would be cylindrical and Slim form factors. The Slim types of form factor with a power bank is one of the most useful because Slim power banks are the same size as your smartphone; so they’re able to fit right in your pocket with your smartphone.

Portability is amazing with these very small power banks as you can literally take them anywhere and that’s why they’re the most used types of ones. With that said, when it comes to the powering side, these power banks are on the short end of the stick. Since having a power capacity of 3,000mAh to 5,000mAh means that they’re really only capable of charging smartphones to their full power at least once or twice.

High Capacity Power Banks

Power banks that have high power capacities are ones that are more useful with their power, but not so much with their portability. Having a high power capacity means the number of batteries that is used is increased and that ultimately makes the power bank larger and heavier.

For all of its other parts, a power bank that has a high power capacity basically excels in all other areas. Since a power capacity, fo 20,000mAh to 30,000mAh means that they’re able to charge smartphones, tablets and a bunch of other devices to full power multiple times over. Another plus on the powering side is the usage of many USB charging ports so you can charge multiple devices at once.

USB Charging Ports

Knowing the charging speeds of the USB ports with a power bank is vital because even though power banks are conveniently portable, you’re still going to want your devices charged to full power in a timely manner.

When it comes to Mini power banks, charging speeds are usually slow as they just have a single USB port. The same thing is true when it comes to recharging Mini power banks with their slow recharging speeds as well because they have low capacities that need to be refilled. However, with newer Mini power banks, there are ones that have faster speeds such as 2 Amps with their ports and there are some that even use USB-C charging to charge compatible devices at max charging speed.

Charging speeds with Power banks that have Multiple USB charging ports

Power banks that have high power capacities and many USB charging ports are the ones where the charging speeds are a lot more important to know.

The reason for that is because if a power bank has 4 USB charging ports and if each of the charging ports had a charging speed of 5V/1.0A. Then that is quite bad since each of the 4 devices that you charge at once will be charging very slowly.

Instead, if a power bank has multiple USB charging ports, you want each of them to have a charging speed of 2 Amps or higher. The reason for that is because most devices are able to charge at noticeable speeds at the 2 Amp range. However, there are other charging speeds that you need to consider such as 2.4A because a 2.4 Amp charging speed is able to charge tablets such as iPads at their max charging speeds.

Also, if you’ve got an Android smartphone, then you have to consider the usage of Quick Charge or USB-C charging tech since most Android devices are compatible with those technologies.

Brands that you’re purchasing

At the beginning of this article, I mentioned how there are many charging electronic companies that now sell power banks. It’s with these many companies that innovation happens but there’s also a negative side and that would be there are a lot of companies that sell low-quality power banks. These types of companies may try to sell their power banks as being the most powerful and compact, but if you were to take a closer look at the specification then you’d see that it’s not true.

That is why it’s vital to know specifications before purchasing a power bank from just any brand. Another major thing to look at is customer reviews because by reading customer reviews you’re basically getting an insight of how your experience will be like.
