For recharging, there is a set of retractable AC prongs that easily slide out at the base, so the unit itself can be plugged right in to any standard 120 volt household power outlet.
The  GPS-1800 stun gun features a master power on / off switch in addition to the thumb operated button used to activate the stun gun, and two red LED's, one letting you know when the unit is on, and the other letting you know when the unit is charging.
Comes with a safety pin. The pin is inserted into the bottom of the unit while the attached lanyard is worn around the wrist. In the event that the stun gun is  taken away, the pin will come out, and the unit will not function without it.
