Starcase Charge & Start, a vintage automotive accessory. Open box; box has wear. Charger like new. Thanks for looking! Instead of connecting directly to the car battery terminals, this device connects the cigarette lighter (12V port) of the "dead" car to the cigarette lighter of a running "donor" car. 12-foot cord to easily reach between two vehicles. This type of product was a "convenience" item for drivers before modern, compact lithium-ion battery jump starters became widely available.
