CTEK (56-304) Comfort Connect Extension Cable, 8.2 Feet

Wanted to get the wiring for my CTEK 3300 cleaned up and reclaim a 50 heavy duty extension cord Id been using on the AC side of the battery maintainer, so I pulled the trigger on this Comfort Connect (aka 12V/cigarette lighter) extension cable. As always, it arrived in two days thanks to Prime. What can I say? Its an extension cable and it works like a champ. If youre currently using the Comfort Connect adapter for your CTEK maintainer and need an extension cable, this is the item for you.

Installed this cable to hardwire my battery tender to my Jeep. I used the M10 eyelet connector and wired them together. I used the rubber protective cap to protect the end of the cable that was exposed to the elements.

Connected perfectly to my trickle charger. Enabled me to move the charger off the windshield of my Porsche and place in on the ground.

I expected the same wire for this extension as the wiring on the CTEK unit. It is no, it is more rigid than my 7002. The 7002 also uses 16awg and the extension is 18awg, disappointed in that as well!

Overall a completely solid productd, high quality manufacturing, and gives me the extra length I need, exactly as descxribed. That said it is pricy for what it is, and there arent any alternatives. However in the big picture it is a tiny cost compared to all the other things one buys for maintaining a classic sports car.

Nice addition to the charger. Better than playing with extension cords. Very good quality wire and connectors.

Works as expected. One thing with high amp products, it might spark sending be surprised. I was in my dry garage during the rain when plugged it in and there was a small spark and noise but I was expecting this. I wish there was a ground on the wall side but understand they attempted to make this country agnostic and wide support.

Does what it’s supposed to do. Quick and easy to connect. Ctek’s Comfort Connect System click is as reassuring as it is mistake proof. I do wish the shielding was thicker or at least matched the quality of the Chargers themselves which would make for a truly seamless extension. As it is, I would still buy it again.

Once the extension cable was connected to the CTEK eyelet or CTEK clamp it did not work. I purchased two different extension cables and both were inoperable. Unfortunately, l had to return both extension cables. When I connected CTEK charger directly to eyelet or clamps NO issues.

Works perfectly with charger as an extension cable.
