USB-Type C charger: Here’s what you need to know

About USB-Type C charger, USB cables are all around us, having become industry standards for connecting, charging, and communicating devices and other accessories. 

Standing for Universal Serial Bus, various versions of USB have been introduced over time. 

Though all USB cables look the same, all have different capabilities related to data transfer and charging speed.

Here, we will discuss a USB-Type C charger and all you get with this charger.

What is USB-C charging?

USB Type-C is a connection standard that can replace all USB types in the computer and other devices with a single reversible connector.

USB type C allows connection of peripheral devices at the speed and power output of USB 3.1, i.e., up to 10Gb/s and 20V at 5 Amperes. 

At this capacity, it can provide 100W of power in all major laptops and support smaller devices. 

Also, there is one compact format in USB-C that can support both the data and power requirements of the devices.

USb Type-C is also compatible with all former USB standards due to its extra pins, but you will need a USB-C to USB (any standard including USB-A, USB-B, Mini and Micro versions) for this. You can also make Thunderbolt 3 connections using special cables.

The device makers plan the device connector with future speed grades in mind. Thus, you do not need to change the cable heads repeatedly.

Here is a list of different USB versions with their maximum data transfer rate and supported connectors.

How does the USB-C charging work?

The working of USB-C charging is a bit different than traditional USB charging.

 It uses a different port to transfer power and data, thus supporting fast-speed charging and higher wattage delivery.

During charging, there is continuous interaction between the charger and the device. As a result, the charger continuously adjusts its output, meeting the device’s needs. 

Also, the USB-C charger has fast charging technology and USB Power Delivery, which can transfer power up to 240 Watts. 

As a result, it is possible to charge your device when it is used for data transfer. 

This port can also transfer power to monitors, external hard drives, or docking stations. And if you use an appropriate cable, it will also support video output.



Understanding USB-C cables and connectors:

There are different types of USB cables, each having unique features and specs. You must know their differences to use the right cable for your device.

One of the two connectors is the USB-C, which is a one-size-fits-all. However, the other end and the cable you use determine the purpose and charging process of the device.

Different USB cables include USB-C to USB-C cable, USB-C to HDMI cable, and USB-C to USB-A cable. 

Among these, USB-C to USB-C cable, which has the same USB-C connector at both ends, is the most common, allowing data and power transfer. 

You can fast-charge devices that support USB Power Delivery with this cable. All USB-C to USB-C cables are not equal.

 Some are rated for 8K video and 240 watts, while some only have 60 watts of rating and do not support video. 

If you want to charge laptops, tablets and phones daily, a 60W cable is good to go.

Besides this, USB-Type C to USB-Type A is suitable for older devices that do not have USB-C ports. 

You can use this cable for data transfer and charging but not for fast charging.

USB-type C to HDMI cables allow you to connect displayed devices like monitors or TVs to your device as they also support video output.

Lastly, Thunderbolt cables with USB Type C connectors support high-speed data transfer at a rate as high as 40Gb/s.

 Thus, you can easily transfer large files easily and very quickly. Thunderbolt cables are versatile as they support different protocols, including PCIe, DisplayPort, and USB. 

A few Thunderbolt cables also allow power delivery so that you can charge your device while the data is being transferred. 

Remember, your device must be Thunderbolt-compatible to use a Thunderbolt cable.

Choosing the right type-C charger:

The right USB charger can charge your device within no time, maintaining its safety. 

Before you pick your USB charger, you must look for the charger’s size, wattage, and the number of ports. 

Besides that, the charger you pick also depends on the cable and the device involved in the charging.

The wattage of the USB-C charger decides its charging speed. A high-watt charger charges your device at a high speed, maximum up to the charging capabilities of the device. 

For example, if you charge your iPhone with a 240-watt charger, it won’t charge fast because the iPhone will draw only about 20 watts of power. 

With this, it is also clear that if a high-wattage charger charges a device with a low-charging capacity, it won’t harm the device. 

This is the magic of a USB-C charger; it only draws volts and amps required by the device.

Ensuring safety with USB chargers:

Though USB charging is safe, you must take precautions to avoid accidental errors. 

For instance, always use genuine and high-quality chargers and cables. 

Low-quality and unreliable chargers can lead to overheating, overcharging, and fire explosion cases.

Do not expose your charger to high temperatures; otherwise, it will get damaged. Always store the charger in cool and dry locations.


Undoubtedly, USB Type-C has become a new and most accepted standard for laptops, smartphones, and other portable devices. 

High-speed data transferring, USB power delivery, reversible ports, and other features have made it the king of the USB world.

However, you must always be careful with the device and the cable you pick.
