CTEK (56-870) Comfort Indicator Cig Plug

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.

Bought to conveniently hook up Porsche to a Ctek charger through the cigarette lighter. Takes just seconds now and it’s nice to have a charging status at point of connection inside the car. Connectors fit Ctek cable securely. Little expensive for what it is, but an effective solution.

Use these on multiple vehicles and ATV 's . Easy way to charge vehicle and LEDs show status of battery charge.

It simplifies maintaining a batter for an over complicated German car. A+

While I am not a huge fan of charging the car battery through the power outlet in the car, this is a nice, convenient accessory if you have any of the CTEK chargers, especially when changing a car battery out. Just put the charger in power supply mode, and disconnect the battery. Retains all of the settings of the radio and ECU. The light is distracting if you leave this plugged in while driving (without the charger, obviously), especially if you are A.D.D. as it continuously blinks while plugged in; it is not a steady light. I thought it would make a nice battery health monitor, but it is too distracting to me. Your mileage may vary. All in all, I recommend getting this to add to your charging kit.

easy to use ,worked perfect to adapt to my Porsche through my lighter rather than connecting to the battery

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.

I have 3 Ctek chargers for all my various equipment. Needed this for its BMW type cig lighter...All good.Genuine product.
