Anyone use an extension cord with their CTEK charger/maintainer, or Porsche branded one? I'm moving and the wall outlet in new garage is further away from my car than current house, and I might need an extension cord. I just ordered from CTEK the 8 ft extension for the red and black cable that goes to the 12 V adapter plug in car, and hopefully that will be enough length.

But CTEK says in underlined print in the manual for the Model 3300, to not use an extension cord to connect the maintainer to the wall outlet, which of course is not what the 8 ft extension I ordered is used for. I don't see why it would matter as long as the extension cord gauge wire is large enough for the amp draw. Anyone use an extension cord and have any issues?

 

I think the extension you are talking about is fine....I have one on mine and it works fine. I think they are likely talking about an extension cord between the wall plug and your Ctek.

 

I use the CTEK 8-foot as well, no issues.

 

I use an old-school Porsche charger. I use the cigarette lighter. FYI. I think the thin cord on the maintainer is about 20 ft long, if that helps. In an old off-site storage facility, I used an extention cord for a few years with zero issues.

 

Yes, I'm sure the extension I mentioned I had ordered is fine. I was asking about a regular extension cord that runs from the CTEK unit to the wall outlet. That's what CTEK says not to use.

 

I've used extension cords with my cteks for years...never had an issue.

 

I have a 100ft extension cord to a CTEK charging my Audi. Works fine.

 

Yeah. It's a CYA statement from CTEK. For long runs I'd use a heavier duty extension cord, but the maximum charging current is about 4A depending on the model.

 

no problem

 

 

The cable between the box and the car is essentially a lamp cord. That tells me that these things don't draw much power. Their warning not to use an extension cord is for fear that someone might use a really crummy extension cord, and perhaps one that's not grounded. If you use a good extension cord, you'll be OK. One of those orange outdoor extension cords is probably overkill, but it is what I'd probably default to because that's what I use in my garage.

 

If you're using the red/black CTEK extension cord (from the CTEK to the cigarette lighter socket), you should be fine. If you're talking about a conventional extension cord (from wall outlet to CTEK) then if you read the CTEK manual for the current/latest models (available online as PDF on their website) they say the following:
