How to Choose the Most Helpful Types of Power Banks

June 15, 2017 by ournethelps

Power banks are portable chargers that can be taken anywhere and they’re one of the fastest growing charging electronics on the market. In fact, power banks have grown in demand so quickly over the years that there are now many different companies that sell them. This has resulted in there being lots of innovation when it comes to power banks and the result of the innovation is that there are many different types of portable chargers now on the market.

This is both a good and bad thing. The good part is that you have a wide range of power banks to choose from; and well, the bad part is that you have lots of power banks to choose from that you know nothing about. Which is why it’s important to know about certain things when you’re going to purchase a power bank. So you’re not stuck with power banks that didn’t have the things you wanted, or one has features that you didn’t want.

Let’s get started on the most important things to know for you choose the power bank that you can find most helpful.

Power Capacity

All power banks have power capacities, as that what makes them portable chargers in the first place. With that said, the power capacity of one controls two main aspects of the portable charger and that would be its size and how you’re able to use the charger. There are ones that have small power capacities and then there are power banks that have high power capacities.

Power banks that have low power capacities are ones that are purchased and used the most. The reason for that is because a low power capacity means that the portable charger is going to be smaller and light weight. These types of power banks basically capture the essence of what it means to be a portable charger because they come in two main forms factors which are cylindrical and Slim shapes. The Slim type of power bank is among the most useful types to own and that’s because they basically have the same shapes and weight as a smartphone, so they’re able to fit right into your pocket.

With that said, as useful as Mini power banks are to take everywhere that we go, it doesn’t mean that they’re perfect from every facet. That’s because a low power capacity of 3,000mAh or 5,000mAh is only able to charge most smartphones to their full power only once, and then the power bank will need recharging. So these tiny chargers are not meant for long-term use.

Then there are power banks that have high power capacities and these ones are not used nearly as much but they’re a lot more useful. The reason for that is because in order to have a high power capacity, a power bank must be using many batteries and that makes them large and heavy. Most of them are not able to fit into a pocket and neither are they comfortable to hold for long periods of time.

Instead, what power banks with high power capacities do excel in the most is their power. A power capacity of 20,000mAh or higher enables you to charge smartphones and other devices to full power multiple times. So these types of power banks can last for days and not need recharging. One of the other parts that makes using these types of power banks impressive is that they use multiple USB charging ports, as a result, you’re able to charge many devices at once.

Charging Power


The Output charging speed of a power bank refers to the charging speed that your devices are receiving. It’s vital to know the Output charging speed because you want the devices that you’re charging to be charged up and ready to go. Even though power banks are portable, there’s still something that you have to rely on for charging and it’s best to be without the weight of a charger than with one.

With that said, most Mini power banks have a slow charging speed of 5V/1.0A but there are now newer Mini power banks that are beginning to use faster-charging speeds. There are even power banks that use USB-C charging which is very useful for those that own USB-C compatible smartphones to charge them at max charging speeds.

Then there are power banks that have multiple USB charging ports and these are the types where knowing the Output charging speeds are most helpful. This is because if you’re charging many devices at once, then you want each of those devices to charge at max charging speeds or near their max speeds. For the most part, 2 Amp charging speeds are the best because most smartphones are able to charge to their max power that way. Then if you plan on also charging tablets then it’s best to go with a power bank that has 2.4A charging speeds.

Lastly, more and more Android smartphones are being compatible with Qualcomm Quick Charge and USB-C. If you own a compatible device with one of those charging technologies, then it’s vital to get a power bank that uses those technologies.


The Input charging speed of a power bank is the recharging of a power bank. Recharging of a power bank matters most with a high capacity power bank because it requires more power to refill. As Mini power banks have very little power to refill and generally don’t need fast recharging speeds.

A good charging method when it comes to high capacity power banks is when they use 2 Input charging ports or if they use Quick Charge or a USB-C Input charging methods.

Brands that you’re Purchasing From

At the beginning of this article, I mentioned how there are lots of companies on the market that are now selling power banks and how it’s a great thing. Of course, there’s a negative side have so many companies that sell power banks and that would be because there are quite a lot of companies that sell low-quality power banks. These types of companies might advertise with a great grandeur of how great their products are with fast charging, and small sizes that you’re able to take anywhere but in reality, their products are actually mediocre.

Most of these low-quality companies are ones that don’t even have warranties.

With that said, in order to purchase a quality product, it’s best to take a close look at what the power bank is capable of with its specifications. Another thing is to take a look at the reviews that a power bank has and base your purchase off of those because a review will give you an idea of what the power bank will be like when you purchase it. Lastly, a company that has a long warranty is one that stands behind their product and that shows integrity.
