The invention discloses an automatically adjusted and butted magnetic adsorption charging method comprising the following steps that S1. a charging head falls on a guide surface from the top to the bottom; S2. the charging head obliquely and downwardly slides to the export of the guide surface under the resultant action of the acting force applied to the charging head by the guide surface and the gravity of the charging head; S3. the charging head falls from the export and finally falls into a magnetic field below the export; S4. the charging head moves to the direction of a charging base under the resultant action of the magnetic force of the magnetic field and the gravity of the charging head; and S5. when the charging head moves to be close to the charging base, the charging base applies the magnetic adsorption force facing the charging base to the charging head so that finally the charging head is enabled to be electrically connected with the charging base. The magnetic adsorption charging method is quite easy to realize, the charging head vertically falls within the small range of the charging base and then is guided and captured by the magnetic adsorption device in the charging base, and the circuit can also be conducted.
