USB-C plug USB-C (SuperSpeed USB 5Gbps) receptacle on an MSI laptop. USB-C, or USB Type-C, is a 24-pin connector (not a protocol) that supersedes previous USB connectors and can carry audio, video, and other data, to connect to monitors or external drives.
[1] [2] USB4 is only defined for USB-C connectors and its Type-C specification [3] regulates the connector, cables and also power delivery features across all uses of USB-C cables, in part [4] with the USB Power Delivery specification. [5] The USB4 standard mandates backwards compatibility to USB 3.x and dedicated backward compatibility with ...
The Certified USB Fast Charger logo indicating support for the Programmable Power Supply (PPS) protocol in USB Power Delivery (PD) chargers. On January 8, 2018, USB-IF announced the Certified USB Fast Charger logo for chargers that use the Programmable Power Supply (PPS) protocol from the USB Power Delivery 3.0 specification. [71]
USB was designed to standardize the connection of peripherals to personal computers, both to exchange data and to supply electric power. It has largely replaced interfaces such as serial ports and parallel ports and has become commonplace on various devices.
The written USB 3.0 specification was released by Intel and its partners in August 2008. The first USB 3.0 controller chips were sampled by NEC in May 2009, [4] and the first products using the USB 3.0 specification arrived in January 2010. [5] USB 3.0 connectors are generally backward compatible, but include new wiring and full-duplex operation.
New-to-existing cables and adapters have been defined. Some USB Type-C cables and connectors can support "USB performance at SuperSpeed USB 10 Gbps (USB 3.1) and USB Power Delivery up to 100W" [19] [20] [21] although USB Type-C cables are only required to support USB 2.0 (non-SuperSpeed) data rates and 3 A (60 W at 20 V) of current.

Quick Charge (QC) is a proprietary battery charging protocol developed by Qualcomm, used for managing power delivered over USB, mainly by communicating to the power supply and negotiating a voltage. Quick Charge is supported by devices such as mobile phones which run on Qualcomm system-on-chip (SoCs), and by some chargers; both device and ...
Thunderbolt 3 has up to 15 watts of power delivery on copper cables and no power delivery capability on optical cables. Using USB-C on copper cables, it can incorporate USB power delivery, allowing the ports to source or sink up to 100 watts of power. This eliminates the need for a separate power supply from some devices.
