Most laptops require between 45w and 85w so they can be charged via their USB port like phones and tablets. This means a laptop can be powered by USB-C at the same time as supplying power to a peripheral.Īs we mentioned with the USB 3.1 Gen 2, USB-C handle can handle up to 100 watts of power. UBS-C is bi-directional, meaning the power flows both ways through the cable. The old USB cables only allowed power to flow from the Type A connector to the Type B connector. Even though you had a 50/50 chance of connecting the old USB cable correctly, it always seemed like it was upside down 80% of the time. One of the biggest physical improvements took a page from Apple’s Lightning connector and is able to plug in whether the cable is flipped or not making it extra easy to use. Unlike previous versions of USB, it has the same connector on both sides so you can plug in either side. It is only slighting larger than the micro USB connector so it will work on small peripherals and even mobile phones. The connector itself is a big improvement. USB Type-C ports can support a variety of different protocols allowing you to have adapters that can output HDMI, VGA, DisplayPort, or other types of connections streamlined into a single type of port. Yes, there are many different types of USB-C cables. It all depends on the specs of the port and on the cable. A USB-C port can be USB 2.0, USB 3.1 Gen 1, USB 3.1 Gen 2, or Thunderbolt 3. The first thing understand about USB-C is that it only describes the connector type. Type-C both ends, reversible plug orientation / Type-A to Type-C (compatible)īi-directional / Host to peripheral (compatible)Įnter USB Type C, more commonly called UBS-C, and this is where things get really complicated. It will probably be 2018 before we see any new hardware sporting USB 3.2.
#UPDATE INTEL THUNDERBOLT 3 2018 UPGRADE#
The only real feature of the upgrade is doubling the maximum speed from 10Gbps to 20Gbps. This will, of course, utilize the USB Type C connector. Just last month, USB-IF finalized the next upgrade, USB 3.2.
#UPDATE INTEL THUNDERBOLT 3 2018 PORTABLE#
While USB 2.0 & 3.1 could power smaller devices like portable drives and phones, USB 3.1 Gen 2 is capable of powering laptops and monitors. Not only did it double Gen 1 speeds to 10Gbps, it also increase the amount of power a device can draw from the host. Still with me? USB 3.1 Gen 2Īlong with USB Type C connector, USB also came out with USB 3.1 Gen 2 which was a big leap forward. Except now, USB 3 is called USB 3.1 Gen 1. However, the USB Type B connector changed for USB 3.0. The USB Type A connector has been been compatible with USB 1.1, 2.0, and 3.0. USB Type B is the other end of the cable that plugs into the peripheral and includes the mini and micro versions and even the Apple Lightning cable for the iPhone and iPad. USB Type A is the original rectangular USB connector that we’ve been plugging into our computers for years. The main thing that USB has done in the name change game is now the connector type is designated by a letter and the transfer protocol is designated by a number. The renaming is a big part of the confusion. To understand the differences between these three, we need to understand the different levels of USB and how they’ve been renamed. Not so easy because they all can share the same cable and use the same transfer protocols… or not. Now we have USB 3.1, USB-C, and Thunderbolt 3.
