I really like the design and functionality of this Crockpot Connectable System. This new system has individual connectable slow cookers that plug into each other to create a substantial tailgating spread. Six crock pots can be plugged together using one outlet. The units are sold individually or as a kit so you can mix and match. Available is a round 2-Qt cooker, an oval 3.5-Qt cooker, and an oval 2 x 1-Qt double cooker.
