The heater fits into a charging base operative to recharge the rechargeable battery through cooperating electrical contacts or an inductive coupling. The sterile casing includes an inner sleeve that fits into the cavity of the heater unit, providing a receptacle to receive and warm the rod of an endoscope or laparoscope.
