In case you didn’t know, the USB connector has seemingly evolved at the speed of light! Computers either have USB 1.0, 2.0, and 3.0 ports, and new specifications are released almost every year. So, the USB is an ever-developing piece of technology, and we most commonly use it to charge our mobile devices.

They just recently announced (2020) the new USB 4.0 (which came out in August 2020), which fortunately will allow us to double our charging speed without changing the cables.

Many of us are accustomed to charging our smartphones by connecting them to USB ports on the computer. It’s convenient, and it makes our phones more accessible when we are using our PCs or laptops. So, here comes the real question: can we charge a mobile phone quickly in a USB port?

The quick answer is that it depends. If you want a brief explanation, check out the first 60 seconds of this video. Once you’re done, read on for more specific information!

How to Charge a Mobile Phone Quickly Using a Computer USB

It is advised to use a charger box and connect it to a wall socket to charge a mobile phone. This ensures the highest charging speed if the charger is in good condition.  

But sometimes, for convenience, or because we have more tasks at hand or limited outlets, we charge our mobile phone by connecting it to a computer’s USB port. This is perfectly valid, and there is no problem in doing so. But on a modern PC, there are USB 2.0 and 3.0 ports, so it is normal to ask: In which USB port will my phone charge faster?

The type of USB port influences the maximum recharge speed. A  USB 2.0 port can supply up to 500 mA, while a USB 3.0 port offers up to 900 mA. But that does not mean that all phones connected to a USB 4.0 will charge faster than a USB 3.0 or 2.0 port. Of course, there are other factors involved.

Specifications of the USB port:

The other specifications are as follows.

The maximum capacity of the battery:

If the battery only accepts up to 500 mA, there will be no difference between using a USB 2.0 or 3.0 port.

The software:

There are smartphones that, based on compatibility, can limit the load to 500 mA when they detect that you have connected it to a USB port, although that port offers more charge power. More modern versions of operating systems disable this limitation when they detect that the port is USB 3.0 or higher.


Not all USB cables are the same. If the mobile accepts the charging at 900 mA and connects it to a USB 3.0 port with a USB 2.0 cable, it will only recharge at 500 mA.

In summary, if you want to charge your phone at maximum speed on a PC, you’ll want a USB 3.0 port and also a USB 3.0 cable. Be sure to check that both the battery and the operating system allow fast charging through a USB port, not just from a charging box.

Note: Make sure you update your USB chargers!

Here’s an important note about USB updates that everyone should know—if it can’t charge quickly, it may be out of date!

Something that may not be common knowledge is that USB chargers can eventually wear out like most other tech gadgets. If they’re particularly ancient, they might be charging your device at only 40% of the speed that they once did! So, if you haven’t purchased a new charger in a while, do it as soon as you can.

Also, the previous steps will still work if you’re in this situation. However, we want to reach our full charging potential when using USBs.

For the fastest charging and safe use, keep in mind these simple tips:

Bonus tips: Here’s how to prolong your USB cable’s most effective charging period:

  1. Keep your USB cord and connector port as clean as possible: this means not touching the USB with greasy fingers or eating while using it!
  2. When connecting the USB to your computer or other port, make sure it goes in cleanly: if it’s upside down, don’t try and force it.
  3. Make sure not to bend the cord if you can help it: try and keep it straight or neatly coiled when possible.
  4. Store it in good conditions: when you’re not using it, coil it up and store it in a dry place until you need it again.

So, these are the best tips to help you quickly charge your mobile device using the USB ports on your PC or laptop. If you are in a hurry, it is quite helpful to do this. Remember to check out your ports’ power—lookup which ports your laptop or computer system has. Then, plug in the pertaining USB cables to the port.
