USB chargers are ubiquitous in today’s world, with nearly every device that can be charged requiring a USB cable. There are two main types of USB ports – Type-A and Type-C – that are commonly used on chargers. Additionally, there are also two main types of charging protocols – the older, slower USB-B protocol, and the newer, faster USB-C protocol. In this article, we’ll take a look at the difference between USB Type-C and USB Type-B chargers.
USB Type-C (or USB-C) is a relatively new standard that was introduced in 2014. It features a small, reversible connector that is roughly the same size as a micro-USB connector, but with several key differences. One of the most significant advantages of USB-C is its ability to deliver more power than previous USB standards. This means that devices can charge more quickly, and can even be powered by the USB-C port.
USB Type-B, on the other hand, is an older standard that was introduced in 2000. It is still commonly used on devices such as printers, scanners, and other peripherals. USB-B connectors are larger than USB-C connectors, and are not reversible. They also do not support the higher power delivery capabilities of USB-C.
The main difference between USB Type-C and USB Type-B chargers is the charging protocol that they use. USB Type-C chargers use the USB Power Delivery (USB-PD) protocol, which allows for faster charging speeds and higher power delivery than the older USB-B protocol. USB-PD is able to deliver up to 100 watts of power, which is enough to charge even large devices like laptops and tablets. Additionally, USB-C cables are also capable of supporting other high-speed data transfer protocols like Thunderbolt 3 and USB 3.1 Gen 2.
Another difference between USB-C and USB-B chargers is their compatibility with different devices. While USB-C is a newer standard, it is becoming more and more common on devices like smartphones, laptops, and tablets. Many newer devices are also designed to be charged with USB-C, and some even feature multiple USB-C ports. USB-B, on the other hand, is primarily used on older devices like printers and scanners, and is not as common on modern smartphones and tablets.
Finally, it’s worth noting that USB-C chargers are also capable of delivering power in both directions. This means that you can use a USB-C charger to charge a device, or use a device to charge another device using a USB-C cable. This is known as “Power Delivery,” and it’s one of the biggest advantages of USB-C over USB-B.
In conclusion, USB Type-C chargers offer several advantages over USB Type-B chargers. They use a faster charging protocol, support higher power delivery, are more versatile in terms of data transfer, and are becoming more common on modern devices. While USB-B chargers are still useful for older devices, it’s clear that USB-C is the way of the future when it comes to charging and data transfer.
