Small devices can be powered directly from the USB interface, eliminating the need for additional power supply cables. Since USB 3.1, which coincides with the introduction of USB-C, improvements have included the directionality of the cable. Previous iterations required specific ends for host and peripheral, whereas USB 3.1 introduced bi-directionality to match the bi-directional connector form of USB-C.In 2008, USB-IF introduced USB 3.0, which ran at a speedy 5 Gbps, offering roughly a 10x improvement in throughput over the preceding USB 2.0. Even today, that’s the top speed that most devices support. In fact, most peripherals only need USB 2.0 speeds.

Vi har især et stort udvalg af USB-C kabler. Vi fører også de populære USB-C kabler til lightning fra Apple. Ligesom vi har alt fra et 1 meter langt USB Lightning kabel til et 3 meter langt USB Lightning kabel. Micro USB kabelThe three sizes of USB connectors are the default, or standard, format intended for desktop or portable equipment, the mini intended for mobile equipment, which was deprecated when it was replaced by the thinner micro size, all of which were deprecated in USB 3.2 in favor of Type-C. There are five speeds for USB data transfer: Low Speed, Full Speed, High Speed (from version 2.0 of the specification), SuperSpeed (from version 3.0), and SuperSpeed+ (from version 3.1). The modes have differing hardware and cabling requirements. USB devices have some choice of implemented modes, and USB version is not a reliable statement of implemented modes. Modes are identified by their names and icons, and the specification suggests that plugs and receptacles be color-coded (SuperSpeed is identified by blue). The USB Power Delivery specification revision3.0 defines an optional Programmable Power Supply (PPS) protocol that allows granular control over V BUS power, allowing a range of 3.3 to 21 V in 20mV steps to facilitate constant-current or constant-voltage charging. Revision 3.0 also adds extended configuration messages and fast role swap and deprecates the BFSK protocol. [57] [68] [69] The Certified USB Fast Charger logo for USB Type-C charging ports
