USB, which stands for Universal Serial Bus, refers to the system that transfers data between computers or between components within a computer, such as a keyboard or a mouse. Consisting of a type of cable and connector, many electronic devices will have a USB connection available, including in vehicles and modern workstation power systems.It is important to remember that your laptop may not be able to charge the device, despite having a USB Type C port. MacBooks can, however, other computers might only charge with their own charger. Though USB-C is a newer and better connector that’s about the same size, you will still see micro USB on a ton of devices, ranging from budget Android tablets to Raspberry Pis, micro controllers, digital cameras, power banks and smart home devices. Technically speaking, there is both micro USB Type-A and Type-B, but you’re only likely to see Type-B. USB Type-C The different A and B plugs prevent accidentally connecting two power sources. However, some of this directed topology is lost with the advent of multi-purpose USB connections (such as USB On-The-Go in smartphones, and USB-powered Wi-Fi routers), which require A-to-A, B-to-B, and sometimes Y/splitter cables. See the USB On-The-Go connectors section below for a more detailed summary description.
USB-C also does away with the variety of previous sizes found for both USB-A and USB-C. It is only slightly larger than the previous micro-B connector, meaning that it is suitable for various devices, from small mobiles and tablets to larger visual displays. This simplicity means USB-C cables are highly interchangeable, so users can store fewer cables. Of course, laptop and desktop ports can also be simplified. Et micro USB kabel kan, ligesom et normalt USB kabel, overføre strøm og/eller data mellem to enheder, og bruges typisk til digitale kameraer og mobiltelefoner. Et micro USB-stik kan f.eks. bruges på Android telefoner. Et micro USB kabel er derfor et must-have for enhver computer og mobilejer. Mini-USB connectors were introduced together with USB 2.0 in April 2000, for use with smaller devices such as digital cameras, smartphones, and tablet computers. The Mini-A connector and the Mini-AB receptacle connector have been deprecated since May 2007. [11] Mini-B connectors are still supported, but are not On-The-Go-compliant; [12] the Mini-B USB connector was standard for transferring data to and from the early smartphones and PDAs. Both Mini-A and Mini-B plugs are approximately 3 by 7mm (0.12 by 0.28in). The Mini-AB receptacle accepts either a Mini-A or Mini-B plug. The following 10 biggest mobile phone companies have signed the MoU: Apple, LG, Motorola, NEC, Nokia, Qualcomm, Research In Motion, Samsung, Sony Ericsson, Texas Instruments (press release), Europa, archived from the original on July 4, 2009Some cables have the same connector at both ends and are named accordingly—for example, a USB Type-C to USB Type-C cable. Interested in USB charging for the office? USB has had several different form specifications for its connectors. Originally, there were just two USB types, USB-A and USB-B. Now, USB-C is joining the game and now changing everything. USB-A a b "USB 2.0 Specification Engineering Change Notice (ECN) #1: Mini-B connector" (PDF). October 20, 2000.

Per the base specification, any device attached to a standard downstream port (SDP) must initially be a low-power device, with high-power mode contingent on later USB configuration by the host. Charging ports, however, can immediately supply between 0.5 and 1.5A of current. The charging port must not apply current limiting below 0.5A, and must not shut down below 1.5A or before the voltage drops to 2V.
