CTEKConnect CIG Plug, Permanent Connection for Hard-to-Reach Batteries, Easy Connection to Your CTEK Battery Charger Using The Vehicle 12V Accessory Sockets, for Cars, Motorcycles & Other Vehicles

Fits the standard12v connection and the lights on the charger indicate it is charging the batteries, as expected.

Outstanding charger! Got this for my garage queen 2019 Corvette Stingray with 11,800 miles on her. Read the reviews and ordered it and had it the next day! Followed the instructions and it worked great! For my Vette I needed to order the cigarette lighter plug as the Vette has one specifically for this charger in the back hatch area and makes it easy to charge Very pleased and fair price too!

If you have a collector car that sits in the garage for long periods of time before use, you must use a trickle charger. I recommend using this 12V adapter rather than battery clamps. It’s more convenient and safer. I have my CTEK charging unit mounted on the shelf right where I pull in my corvette. I simply open the door, grab the plug wire and insert it into the accessories plug in my car. This one is well made and not cheap.

As described, works great.

Fits perfectly and gives a nice options. For charging method.

Straight out of the box, setup was easy going from battery clamps to lighter plugin,I was charging a trickling with 15 minutes. Had to read instructions to read the meter, but it all made sense. Talked to Porsche dealer who said the sold the same manufacturer with Porsche name and 3 times the price. Do your car the favor and get one!

If you plan to use a CTEK battery tender and do it easy for connect/disconnect, the preferred option is to use a cigarette lighter receptacle inside the cabin; but instead, the included connection option with any CTEK tender is to supply only a connector to be used directly to the battery, which is located under the hood (or for some models inside the trunk). That's mean every time the hood/trunk need to be open (and let "semi-open" to avoing kink the cable) wich is impractical (at least in my case) as the hood of my car is very tight and if keep open, a indication in the dashoboard keep on. So this cigarette plug adapter is a must for "practicality" if you want to connect easy your CTEK to keep in top condition the battery of your sport car. The only thing is, as I said in the title, this plug adapter should be included with the CTEK Battery Charger, and not as an additional accesory. All in all recommended to spend a few bucks more with this and make life easy.

Works as described and is actually a quality product. Using on my C6 Z06.
