Abstract: A portable electronic system including a body and a dock is described. The body has a waterproof first connector and a first attracting portion, wherein the first connector has a plurality of electrical terminals. The dock has a second connector and a second attracting portion, wherein the second connector has a plurality of retractable pogo pins. When the body is placed on the dock to make the first connector connected to the second connector, the magnetic force between the second attracting portion and the first attracting portion makes the electrical terminals compress the retractable pogo pins to a critical distance to achieve the electrical connection between the body and the dock.
