Questions about Ctek Comfort Connect Eyelet M8

Unfortunately, this is only a connector plug for a CTEC charger. I also had to change the terminals for the connection to the battery. The coupling to the CTEC devices does not conform to any standards - you have to find your own couplings that meet your requirements.

I cannot answer the question as I am only a user and have used this with the Ctec mx10.

The cable has a female part and can be connected directly to the cable of the charger (male part) instead of the clamps. It is often useful to buy the extension cable as well, to use as a middle piece. Especially for Ctek chargers.
