![]() ![]() Standardization on USB for charging devices has been primarily intended to reduce electronic waste by doing away with having a separate proprietary charger for every electronic gadget. USB has gained wide international adoption for battery charging, especially for mobile electronic devices. The hype on Type-C can be misleading, and there’s more to it than, “One cable to connect them all.” If you want the very short explanation, here’s my best advice: to avoid confusion, don’t ever buy anything but a cable that is certified as a Type-C, USB 3.1, and USB PD compliant cable. And thanks for making me really curious about USB Type-C and why a Type-C cable can still be certified but unable to stream video to your 4K HD screen from your Type-C Chromebook. Thanks Benson, for doing the right thing. He also said that the Superspeed+ (10Gbps) cables should have a SS+ USB mark on them. had heard about Benson’s crusade and was very clear that Qualtek’s cables are indeed certified. Nuti, to see if Qualtek’s USB Type-C cables are certified, and how to tell. This concerned me, so I checked with Qualtek’s engineer R.J. The USB-C standard is somewhat new, and so cable markings or logos for USB Type-C certification are not clear yet for even the ones who are legitimately certified. Turns out that this amazing connector that will de-clutter our lives by channeling up to 10 Gbps data and 100W power in one small cable has many not-quite-right cables flooding the market. I was intrigued to hear that Benson Leung, a Google engineer working on the Chromebook Pixel, had gone on a one-man crusade to help early adopters of USB Type-C technology (used in the Pixel) to review Type-C cables online to weed out the ones that were not USB Type-C spec compliant.

Buying Guide and Advice. ![]() Laptop Tech Support Showdown: Undercover Report.While having a univeral connection standard is best for users, it hurts the bottom line for vendors who want to sell replacement power bricks at $50 a pop. ![]() It will be interesting to see whether other notebook vendors start adopting USB PD. So, just because you have USB Type-C, that does not mean you have USB PD.Īpple has not specifically used the term "USB Power Delivery" in its documentation for the MacBook, but the notebook must be using this specification because it's connected to a 29-watt power adapter. USB Type-C can support USB Power Delivery if the device's host controller and the cable itself support the standard. You would be able to use the adapter that came with your Dell laptop when you switch over to a notebook from Lenovo, just as you can use your Samsung wire and AC adapter with your LG phone. Where today every make and model of laptop uses a different kind of power connector, tomorrow all laptops could have USB Type-C connectors with USB PD. The best thing about USB PD is that it could spell the end of the proprietary laptop power brick. With USB PD, you could connect your laptop to a monitor and send a 4K video to the display, while receiving a full power load from it. USB 2.0, the most common connector for smartphones and tablets, usually caps out at about 2.5 watts, enough for small devices, but a far cry from the 20 to 65 watts that most laptops need at any given time. USB Power Delivery is a specification standard that allows devices to send or receive up to 100 watts of electricity over a single connection while transmitting data at the same time.

According to the USB Implementer Forum, which is in charge of creating USB standards, USB 3.1 Gen 2 delivers the full 10 Gbps of throughput. The MacBook's connection is listed as "USB 3.1 Gen 1 (up to 5 Gbps)" so it caps out at the same maximum as USB 3.0. USB 3.1 connections are backward compatible with USB 3.0 and USB 2. In real-world testing of a first-generation USB 3.1 controller, Tom's Hardware got read and write speeds well over 700 MBps, nearly double the transfer rate of the same SSDs connected via USB 3.0. USB 3.1 is a new standard for high-speed data transmission that more than doubles the theoretical bandwidth of the USB 3.0, going from 5 Gbps to 10 Gbps. The MacBook spec sheet says its USB Type-C port is USB 3.1 (gen 1) compatible. USB Type-C cables and ports may used for USB 3.1, but, depending on the host controller and devices, may only be compatible with USB 2.0 or USB 3.0. ![]()
