Review on 🔌 Pwr 12V DC-Power-Cord 25121 for Igloo Cool Chill, Kool Mate, Iceless TE Cooler - Reliable Car Charger Power Adapter with Extra Long Cord for USA Travel & Business by Dan Bobbert

The build quality is much better than I expected. The OEM cable eventually melted the tip due to a loose connection in the car socket. The 120V to 12V adapter has also been weakened. This stays firmly in place and has a large contact area, and the springs feel much stronger. Only used for an hour or so but would buy more. With the OEM, it was sometimes difficult to tell if the power light was on in daylight. You can use this almost like a mini flashlight.
