Abstract

An electronic device includes a charging station and a main unit. The charging station has a first electrode and a second electrode. The first electrode and the second electrode form an angle therebetween, and the main unit has a third electrode and a fourth electrode. When the main unit is connected to the charging station, the main unit firstly contacts the second electrode with the fourth electrode, and then contacts the first electrode with the third electrode, so as to be recharged by the charging station.

Claims
