The popularity of USB

  • USB – Universal Serial Bus
  • Present on most Laptops, Desktops, Tablets, Mobile phones and charging devices
  • Passive USB simply provides data
  • Well established technology
  • Reliable
  • Now capable of delivering power, data and video capability over one connector
  • Very easy to configure and use
  • Older generation USB2.0 run at 480Mbps over 4m
  • Newer generations such as USB3.0 Gen1 run at 5Gbps over 1m
  • USB3.1 Gen2 provides 10Gbps @ over 1m
  • USB4.0 (USB-C) provides 40Gbps over 0.8m and support

upto 100W over power transfer

Physical connection


  • Relates to interconnection format more than anything
  • Oval connector, allows insertion in either direction
  • Compatible with Thunderbolt (Intel) and Lightning (Apple) connectors
  • Ultimately the objective is to have one interface through which all electronic devices can be charged, powered and operated (data Tx/Rx)
  • All new Apple laptops are being built with USB-C capability only
  • By the way “PD” used in the context of USB relates to “Power Delivery”… not to be confused with PoE PD (… Powered Device) !!!
