What Type Of Charger Can You Use For A Power Bank?

Most of the time, power banks do not come with a dedicated charger with them. They just have a charging cable but no power brick to connect it with. 

Even though some good brands like Anker and RAVpower sometimes include a charger with the package, it will usually cost you more to go for those options. But don’t worry if you received your power bank without a charger, as there are other alternative ways to charge it without a dedicated charger. 

In this article, we will be going over the following sections to help you understand what type of charger you can use for your power bank:

  • Using a phone charger for your power bank
  • Considering the charging speed 
  • Fastest charging adapters for your power bank
  • Prong types

To conclude this article, we will be telling you the best charger you can use to charge your power bank. Let’s get right into it. 

Using a Phone Charger For Charging Your Power Bank

It is very likely that you have one or more phone chargers lying around in your household. Although you can use a smartphone charger to supply electricity to your power bank, it is essential to consider the port type before attempting it. 

Most power banks in the market are equipped with a micro USB  port used to charge them. However, many modern smartphones have a Type-C charging port. It means that you won’t be able to use a majority of smartphone charging cables to recharge your power bank. 

Also, if you have an iPhone, the Lightning cable won’t be of any good either. Therefore, it is crucial to get a compatible phone charger to work with your power bank. Once you have it, there are two ways you can use the charger to charge your power bank. 

  • Direct Supply: To charge your power bank using a phone charger, simply connect it to the cable and plug in the adapter to the socket. If it is compatible, the lights on your power bank will indicate whether it’s charging or not. 
  • Using a PC: If you wish to charge your power bank using only the smartphone charging cable and not the adapter, you can do so with the help of a computer. To do this, pull out the cable from its adapter and plug the USB-A end into your laptop or PC. Connect the other end to your power bank, and it should draw current from your computer. It’s better to use a USB 3.0 power as it has a higher current output of 0.9 Amps compared to 0.5 Amps of USB 2.0 ports. 

Considering The Charging Speed

If you choose to use your smartphone charger for your power bank, you might not get the same results you would with a dedicated power bank charger. That’s because smartphones have smaller batteries than power banks, and their chargers are designed to charge them optimally. They might not function at their peak when plugged into a power bank. 

As a result, your power bank will likely charge slowly. In some cases, it can take up more than six to seven hours. Although you can’t avoid it entirely, there is a workaround that will let you charge your power bank a little faster. Various power banks imply fast charging technologies like QC or PD. You can get a smartphone charger that supports these technologies to suit your power bank better. 

Fast Charging Adapters For Your Power Bank

As mentioned earlier, power banks charge faster with their dedicated charger. If you use a smartphone charger, the power bank will significantly take more time to charge. To increase the charging speed of your power bank, you’ll need to consider the maximum input it can handle. You can find all the information related to this on the box or the back panel of your power bank.  

If you supply more power than the maximum limit of the power bank, it is possible to charge it faster. To do this, find an adapter that has more power ratings than your power bank. The additional current won’t damage your power bank battery as it will refuse to take in the extra potential. But a powerful charger will push in more current that can charge your power bank faster. 

As we mentioned before, modern power banks use fast charging technologies like QC and PD. Some options utilize newer technologies like GaN that provide an even quicker charging while still keeping the power bank compact. You can find an adapter that is compatible with these techniques to charge your power bank optimally. Here’s what these charging technologies mean:

  • QCDeveloped by Qualcomm, QC or quick charging is one of the most common fast charging techniques modern battery designers use. 
  • PD – PD or power delivery charging allows your device to draw more power in a short period to charge quickly. Many modern devices such as smartphones, tablets, and power banks are PD-enabled. 
  • GaNIt stands for Gallium Nitride, which is a material used for building semiconductors in chargers. It generates less heat, which allows the designers to cram in more components in less space. That is why modern power banks have shrunken in size while being more potent than before. 

Prong Types

If you are purchasing a power adapter to charge your power bank, make sure to get the correct prong type according to the sockets in your household. That’s because different regions of the world use different types of electrical sockets in their homes. 

It is not an issue if you are ordering within your country. However, if you are purchasing a power adapter online from a different region of the world, it might not be compatible with the sockets in your household. You can also invest in a multi-prong socket. It is a small wall socket adapter that has multiple sockets of different types. It allows you to freely travel around the world while still being able to plug in your appliances such as power banks in domestic sockets. 


If you purchased a power bank that comes without a charger or lost the one it had, it may seem challenging to recharge your power bank once it is discharged. However, as we learned today, that’s not the case. If you want, you can use your smartphone charger to charge your power bank. Although it doesn’t function with the same efficiency as a dedicated charger for your power bank would, there are still a few workarounds you can do to fast charge your power bank.

We recommend investing in a power charger that can supply more current than what is actually required by the power bank. It won’t damage your device, but it can marginally increase its charging speed. 

Additionally, you can also look for adapters compatible with fast charging technologies such as QC, PD, or GaN. However, if you’re ordering one online, be sure to take the prong types into account, or you’ll be stuck with an adapter that doesn’t plug into your household sockets.
