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

Works with both of my CTEK chargers and makes them more convenient to connect in the garage. The wire, however, is unusually stiff and almost awkward in this application. It is much stiffer that typical stranded copper or stranded copper-clad wire, almost like solid wire as it holds shape when bent or coiled.

For the few dollars, this ctek extension is very convenient. At an extra 8 feet, it may not avoid having to pull out an extension cord. But it avoided me having to balance the charger somewhere on the car (especially bigger cars), dragging a thicker home extension cord onto cars finish, and a little more choice for safe placement on the ground. Recommended!

My charger sits next to my car and theres times I need a 12 volt plug and I dont want to use my car battery. I have an RV battery being trickle charged so I just use this cord and it works great. Highly recomended.

The connectors work well, just wish it would have had the specs in the listing. It is only 16AWG and can support 10A Max. I was planning on splicing it into my 12AWG, 50A system, but cant now.

Perfect extension for easier access when charging.

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

Quality built. Works fine. Purchased to maintain the battery in my C8 Corvette.

***See update at end*** I have my CTEK battery tender on a shelf and use this extension to reach into my car, via a CTEK cigarette lighter adapter. About every other day I find the lights blinking indicating a poor connection. I have tracked down the problem to the coupling between the main unit and this cable. The clips fasten tightly, everything is clean and firm, yet when the fault occurs the slightest touch will restore connection, only to fail again sometime later. Its unknown what causes it to break connection as this runs through a completely undisturbed location in a very clean garage. The convenience of the extra length is great, but the reason for being is to maintain a battery and its not doing its job. Relying on this to keep your battery topped up will result in disappointment if its prone to random failure such as this. I cannot recommend it. UPDATE: I unclipped the Comfort Connect cable and very carefully applied a conductive paste (Ox-Gard) with a toothpick inside each of the two barrels of the female side of the connector, then reconnected. This has solved the problem and the connection is now stable, device working properly. Sloppy build quality but easy fix.

Used with a Ctech charger perfect, The small cord fits through the door on my 911 and works perfectly with the charger it takes seconds to hook up and is maybe have to charge of the Porsche charger and really the same charger but not with the Porsche label on it.

I recommend this extension. Your power outlet may not always be as close and you may not have a power extension box. Due to the length of the cable that attached to the tender, this makes it easier to run your cabling from you hood such that you close the hood while the battery is being charged.
