USB-C 2.1 Could Quickly Charge Our Laptops and Smartphones

USB Type-C, which is currently found in most recent smartphones and laptops worldwide, is an upgrade that will enable it to deliver up to 240W of power. The existing USB Type-C port has a maximum capacity of 100W, 140 percent less than the new USB Type-C port.

Manufacturers will inevitably need to modify the USB Type-C accessories bundling to provide more power. However, there will be no modifications to the user interface as it currently exists. You will continue to receive the same reversible port on your devices, but they will be able to handle more power.

The USB Implementers Forum (USB-IF), an industry organization promoting and supporting the Universal Serial Bus, also known as USB, has published version 2.1 of the USB Type-C specification. That is the first time that the USB Type-C specification has been revised.

Next-generation USB-C 2.1 cables may finally be on their way, potentially reducing the time to charge our laptops, smartphones, and other electronic devices.

Club3D has come out with a new line of USB-C cables that can deliver up to 240W of power, which is more than double the maximum power that current USB-C cables can deliver.

Club3D now has three of the first USB Type-C cables that are EPR-compliant, but they use different USB standards for data transmission. Even a "pure charging cable" that only uses USB 2.0 with 480 Mbit/s and doesn't have a toggle to support DisplayPort mode is available. Retailers will get their goods in early May.

That could significantly impact laptops and phones that use USB-C to charge. Because USB-C is faster than USB, laptops, and phones that use USB-C will be able to charge much faster. The latest USB update, which has a charging capacity of 240W, may enable laptop manufacturers to abandon traditional barrel jacks in favor of modern USB Type-C ports for charging and data transfer on their devices.

This increased power supply may also mean that more power-hungry devices will be able to charge using USB-C for the first time, rather than proprietary chargers typically included with large, bulky, and heavy power supplies. 

Analysis: These New Cables Are Versatile

It looks like Club3D has three cables, all of which have 240W power. These new cables could be beneficial, too. Unfortunately, there's no video output, and it only has USB 2.0 data transfer speeds of 480Mbps. That makes the CAC-1573 look like it's the most basic model. USB 4 speeds of up to 20Gbps and 4K 60Hz video are available on the CAC-1575.

Finally, the CAC-1576 cable looks like the best one, with USB 4 speeds of up to 40Gbps and support for 8K video at 60Hz. As long as the other two cables are, the CAC-1576 is just one meter.

People can plug any USB Type-C 2.1 device into a USB Type-C 2.0 port, which won't make any difference. However, when you unplug your USB device, there could be an electrical arc. USB-IF says that ERP-compatible sources and sinks will have to be able to handle this.

People also need to ensure that EPR cables are "clearly marked with ERP cable identification items." 

The USB Power Delivery (PD) protocol, which operates on the USB Type-C interface and can deliver up to 100W of power, is used by most mainstream laptops these days. However, some gaming laptops and desktops require a higher amount of output. That is an area where the new standard may be of assistance.
