What Is the Difference Between USB-A and USB-C Charging?


A cable, converter, or flash drive can all be connected to your computer using USB. Its primary purpose is to provide power or aid in peripheral communication with a computer. Since about the middle of the 1990s, USB-A has been the industry standard for everything from mice to keyboards, flash drives to gaming controllers, and converters to charging connections.The peripherals that connect to computers must advance at the same rate as computer technology. Since its debut, USB-A has gotten quicker thanks to advancements in USB 2.0 and USB 3.0, but USB-C, a new form of USB connection, has entered the fray.

What is USB-C?

In the realm of technology, USB Type-C is a relatively new creation. Although it originally materialized in 2014, it took a few years before it gained widespread acceptance. The designs of USB-A and USB-C differ slightly from one another. There is no correct or incorrect method to plug in a USB-C device because USB-A is a reversible, unidirectional input.There are more differences between USB-A and USB-C than just their appearance. With the use of adapters, USB-C may also be used to connect a variety of peripherals, including HDMI, DisplayPort, VGA, or DVI connections, as well as an Ethernet connector, to your computer. So, how do the charging abilities of USB-C and conventional USB-A compare?

Charging Capacity: USB-A Vs. USB-C

You want a charging cord that can charge a smartphone effectively and rapidly. Let's compare the power output of USB-A and USB-C cables while they are charging.

USB-A Charging Power

When it comes to charging power, USB-A has advanced significantly. In the beginning, the highest power output was 2.5 watts via a computer connection or 5 watts from a specialized charging block. Fortunately, as technology has advanced, certain USB-A adapters have embraced the USB-IF Battery Charging protocol or other proprietary fast charging standards like Qualcomm's "Quick Charge," which, as of the QC 3.0 iteration, can deliver up to 36 watts of electricity.

USB-C Charging Power

There is a reason why USB-C chargers have risen to the top of the market. The maximum power output for a USB-C adapter is 100 watts, according to the USB power delivery specification. But with the most recent PD3.1 EPR revision, adapters may now deliver up to 240 watts. It is crucial to remember that in order for your device to utilize the maximum wattage of your adapter, it must be able to support rapid charging.You can use a charging cable without an e-marker chip if the adapter you are using is 60 watts or less. However, you will need a cable with a typical e-marker chip when the wattage exceeds 60.The ability to charge bigger devices, such as tablets and some laptops, is one of USB-C's finest advantages.While USB-A is still a dependable source to charge your phone at night, it might be time to convert to USB-C if you want a speedier charge or need to charge a larger device.
