USB power

Cable-delivered device charge

USB power is electrical power delivered through a USB (Universal Serial Bus) connection, allowing devices to charge or operate without a separate power adapter.

Originally designed for data transfer, USB ports now commonly supply power to phones, tablets, and small electronics: The laptop provides USB power to charge my phone.

USB power has largely standardized charging across devices.
