A high efficiency bobbin winding device with adjustability has a housing that encloses at least one motor and associated circuitry and mechanism that allows a user to selectively wind a bobbin with a selected amount of thread. The motor is mounted on a hinged support that rotates to move the motor which has a shaft that spins the bobbin. An adjustment knob is rotated to selectively move the motor support. A sensor detects the amount of thread wound on the bobbin and stops further winding when the proper amount of thread is wound on the bobbin. The housing also has indicator lights to indicate power and other settings. A spool is placed on a rod and is thread through a guide and a tension adjustment and then on the bobbin where it is wound to a selected level.
