CTEK (56-870) Comfort Indicator Cig Plug

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

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.

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.

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.

Just what I needed CTEK Products are the best!

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.

Worked as expected

Works as advertised Can plug this into your 12V outlet to immediately see Green, Yellow or Red light & know the state of charge of your car battery. But the reason to buy this is when you own a CTEK battery charger, you need not connect that charger directly to your car battery. This can be very useful for those who have hard to access batteries, like me. Mine is underneath the rear cargo floor & requires removal of the spare tire to access the battery! Even if your battery is relatively easy to access, this allows you to charge it without leaving the hood open. You can route the CTEK A/C cord out one of the windows. I use with CTEK (56-864) MUS 4.3 Note: make sure your 12V outlet is on after shut off ignition. If yours are OFF when ignition off, check with your manufacturer to see if can still use to charge battery. Some are programmed to turn off so you cannot run things using current from your car battery when ignition is off but, it WILL allow the battery to be charged via the 12V outlet.

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.

This product provides an extremely simple but accurate way to monitor charge status of a car battery on a rarely used vehicle without even having to "pop the bonnet" to connect a multi meter. If the battery does need charging, it so very simple to use the "comfort connect" connection from a C Tek charger to connect directly to the device leaving the C Tek charge status lights visible through a window on a seat inside a locked vehicle - genius! There have, sadly, been some negative and ignorant reviews of this product which may needlessly discourage purchase of an otherwise excellent product. Firstly, the need to connect to a permanently live cigarette lighter socket should be obvious - it's not a surprise! Fortunately, the 2 x Skodas within my extended family both have such permanently live sockets and find that this device is so simple to use. Check before buying.! But - even if your car does not have a permanently live socket on dash or centre console - don't give up - check to see if there is a permanently live socket in the boot. Secondly, there are some negative reviews criticizing the voltage value of the Amber/Green threshold. Without wanting to start an online spat, I regard the 12.65V threshold as wholly appropriate for a "fully charged" vs "charge soon" boundary. If your car battery is not above 12.65V it is at least 20-30% discharged and some electric wizardry from a C Tek charger would be beneficial to extend battery life even if not immediately essential to starting the engine. Only downside, £15 is not cheap for what it is, but it could save you hundreds of pounds. Quality has a price.

Perfetto per la connessione tramite accendisigari o presa interna. Attenzione perché alcune auto (per esempio BMW) disattivano la presa accendisigari dopo alcuni minuti rendendo impossibile la carica.
