USB 3.1 SuperSpeed+ offers a whole new level of connectivity. Transfer data at incredible speeds, charge other devices, and even power mobile devices - all with just one USB-C cable.
Quickly becoming the new universal standard, USB 3.1 is already supported by Windows, Google, and Mac operating systems, as well as many peripheral manufacturers.
FASTER DATA TRANSFER
Transfer data at up to 10Gbps with improved cables and connectors. USB 3.1 offers faster rates than ever before. Fast enough to transfer a year's worth of music in 10 minutes or an entire HD movie in just 30 seconds.
POWER & CHARGE OTHER DEVICES (see details below)
This USB-C cable supports up to 3A of power output for charging USB-C devices.
Cablek offers the following USB3.1 TYPE C cables:
USB3-CC-MM-3 USB3.1 TYPE C Male to TYPE C Male 3 feet
USB3-CB-MM-6 USB3.1 TYPE C Male to TYPE B Male 6 feet
USB3-CA-MM-3 USB3.1 TYPE C Male to TYPE A Male 3 feet
USB3-CA-MF-6IN USB3.1 TYPE C Male to TYPE A Female Adapter 6"

A.2 Voltage Selection Rationale: Voltages used by the profiles were not picked randomly; this section describes the rationale behind the choices.
5V is the USB default that must be supported to provide interoperability with existing Devices. However, higher voltages are needed to provide more power through USB connectors because of their current carrying capability.
12V was selected because it is very common in PCs and many other systems. The current limitation of the Micro USB Connector family is 3A for the enhanced PD version. The use of 12V with 3A provides sufficient power to charge tablets in the 20-30W range that use the Micro USB Connector.
20V was selected because larger systems, such as notebooks, often have 4 lithium cells in series and require charging voltages in the 18-20V range. A sampling of systems showed that chargers for these systems were typically 19.5-20V. Typical systems had chargers that supplied between 60W and 100W with the exception of a few very high-end performance systems that were well over 100W. The 5A current limit of the PD enhanced Standard-A and Standard-B connectors, with 20V allows up to 100W to be delivered to charge this class of Devices.
A. Power Profiles
A.1 Profile Definitions
There are the following profiles based on Fixed Supply Objects:
Profile 0 reserved
Profile 1 capable of supplying at least 5V @ 2.0A
Profile 2 ports are capable of supplying at least 5V@ 2.0A, 12V @ 1.5A.
Profile 3 ports are capable of supplying at least 5V @ 2.0A, 12V @ 3A.
Profile 4 ports are capable of supplying at least 5V @ 2.0A, 12V and 20V at 3A respectively.
Profile 5 ports are capable of supplying at least 5V @ 2.0A, 12V and 20V at 5A respectively.
Power Profiles are defined to overlap such that a Device that requires a Profile 2 Source will operate equally well when connected to a Profile 2 or any higher Profile Source.
Sources may have additional capabilities. For example a Source might advertise 5V @ 3.0A, 12V and 15V at 1.5A respectively. It is a Profile 2 Source because it meets the Profile 2 requirements to supply 5V @ 2.0A and 12V @ 1.5A. The fact that it can also supply 5V @ 3.0A and 15V will have no effect on a Device that wants a Profile 2 source.
Profile 5 Sources that are capable of 100W operation are subject to various worldwide safety standards. In order to meet the most common safety standards, the continuous output power cannot exceed 100W and the continuous output current cannot exceed 5A. The industry is well versed in meeting the safety requirements for such power sources (e.g. Wall Warts). Refer to Figure A-1 for an interpretation of the safety requirements imposed by IEC/UL60950 Table 2B.
