All CTEK accessories are designed to be used with only CTEK All chargers below 10A use a black and orange plug connector which is inline between the charger and alligator clips. These are called Comfort Plugs and are unique to CTEK. The charger comes with a male plug on it so all accessories have the female socket on them.

When you purchase a new CTEK charger all the models up to the 10A include a set of alligator clips and a comfort eyelet plug which has 6mm eyelets for permanent attachment to the battery.
