Abstract: The USB AC adapter with removable USB vehicle power adapter comprises of a housing with a slot that holds a removable vehicle power adapter. The housing has an alternating current plug adapted to be insertable into an alternating current source. The housing further encloses a universal serial bus. Power conversion circuits are enclosed in the housing to convert the 110V alternating current to both 5V and 12V direct currents. The 5V direct current is directed through the universal serial bus in the housing. The 12V direct current is directed to the slot that holds the removable vehicle power adapter. The removable vehicle power adapter is adapted to be removable from the housing and insertable into a vehicle's cigarette lighter socket and converts the 12V from the vehicle's direct current power supply to 5V direct current output through a universal serial bus.

Abstract: A switch for universal serial bus is disclosed. The universal serial bus (USB) port has a built switch actuator that automatically turns power on and off upon insertion and removal of a USB plug. The switch for universal serial bus comprises of a USB port with a switch actuator in a power-off position and a momentary switch wherein when a USB plug is inserted into the USB port, the switch actuator is depressed which in turn depresses the momentary switch to turn on the power to the USB port. When the USB plug is removed from the USB port, the switch actuator returns to its original power-off position thereby turning off the power to the USB port.
