Sking the off board charger is a 5 inch by 3 inch rectangular box with a power plug on one end and a round silver 3 prong plug on the other. The charger plugs into the charger port located under the front of the joystick. Plug the charger plug into the joystick and then into the wall socket. When it is fully charged the light on the chrager will turn from yellow to green. Unplug the power from the wall socket first then unplug from the joystick In ither words always have the charger unplugged when you plug the charger up to the chair Now if the chair has an onboard charger there should be a power cord that just plugs into the chair usually somewhere in the rear of the chair all you have to do is plug it into a wall socket and charge away Hope this helps you
