Disclosed are a gyroscope and a charging device. The gyroscope includes: a casing, a motor, a circuit board and at least two tilt switches. The casing is provided with a rotation axis, the motor is fixedly mounted on the casing, an output shaft of the motor is coaxial with the rotation axis, an end of the output shaft away from the motor is located outside the casing, and the casing is rotatable around the rotation axis with the end of the output shaft away from the motor as a fulcrum. The circuit board is provided with a power supply and a current amplification circuit, the motor is connected to the power supply through the current amplification circuit. The at least two tilt switches are connected in series to the current amplification circuit for jointly controlling an on/off of the current amplification circuit.

A first correction voltage generation circuit provides a first positive or negative correction voltage for correcting an input voltage. A second correction voltage generation circuit provides a second correction voltage identical in polarity to the first correction voltage in accordance with the first correction voltage. The second correction voltage is generated to have a temperature coefficient reverse in polarity to a temperature coefficient of the first correction voltage.
