Full-featured USB-C 3.1 cables are electronically marked cables that contain a full set of wires and a chip with an ID function based on the configuration data channel and vendor-defined messages (VDMs) from the USB Power Delivery 2.0 specification. USB-C devices also support power currents of 1.5A and 3.0A over the 5V power bus in addition to baseline 900mA; devices can either negotiate increased USB current through the configuration line or they can support the full Power Delivery specification using both BMC-coded configuration line and legacy BFSK-coded V BUS line.

All devices must act as low-power devices when starting out as unconfigured. For USB devices up to USB2.0 a unit load is 100mA (or 500mW), while USB3.0 defines a unit load as 150mA (750mW). Full-Featured USB-C Fabrics can support low-power devices with a unit load of 250mA (or 1250mW).

Ethernet standards require electrical isolation between the networked device (computer, phone, etc.) and the network cable up to 1500VAC or 2250VDC for 60seconds. [111] USB has no such requirement as it was designed for peripherals closely associated with a host computer, and in fact it connects the peripheral and host grounds. This gives Ethernet a significant safety advantage over USB with peripherals such as cable and DSL modems connected to external wiring that can assume hazardous voltages under certain fault conditions.

Oppo Super VOOC Flash Charge, are also known as Dash Charge or Warp Charge on OnePlus devices and Dart Charge on Realme devices The chipset and drivers used to implement USB and FireWire have a crucial impact on how much of the bandwidth prescribed by the specification is achieved in the real world, along with compatibility with peripherals.

As such, USB devices often do not have user-adjustable interface settings. Upstream USB connectors supply power at a nominal 5 V DC via the V_BUS pin to downstream USB devices. Low-power and high-power devices remain operational with this standard, but devices using SuperSpeed can take advantage of increased available current of between 150mA and 900mA, respectively.
