works perfectly. Love the way it attaches to the CTEK charger

Great CTEK accessory plug
If your vehicle has a cigarette lighter receptacle which can be used to charge/maintain a battery, this is the perfect plug lead to use with a CTEK battery maintainer. Just unplug the battery terminal clips from the main DC power line and plug this lead in.

Works perfect for PORSCHE
I bought this accesssory to use with the 12v outlet in my Cayenne Turbo. Porsche specifies a particular height for the prongs of the plug inside the outlet in order to avoid damage. This part and the CTEK charger I use it with are the exact same pieces that Porsche sells as part of their accessory range minus the Porsche logo. So, you are assured that this meets the requirements for use in your Porsche and you save about 40%. Of course it works great if it's good enough for Porsche, so I'm sure you would be happy with it in whatever vehicle you drive. The conditioning and maintainance feature of this unit leave my vehicle ready to go at any time regardless of how long it has been sitting. I am totally happy with the performance and although it was not the cheapest option, I feel that this is a good vale for a quality piece of garage equipment.

Works, but not sure of the purpose.
Works well, but not sure of the purpose now that I have it. It does plug into the CTEK system like it should, and shows the battery level, but the CTEK unit itself already has indicator lights. I don't leave it plugged in when I drive, just because it looks stupid and blocks the outlet. So yes, it works just fine, but at least in my opinion, is totally worthless. Just get the regular lighter socket plug, no need for the indicator lights.

Works well with my charger. Easy to connect to the battery compared with a direct connection.

My broken Porsche branded smart charger came with an attached cig plug, but this plug is better as it comes with indicator lights.

CTEK is the best battery conditioner on the market and these adapters are useful to have around if you have multiple cars .
