Has anyone used the comfort plug with a 2002 Porsche 911? Did the key need to be in the ignition for the battery to charge?

The easiest way to answer this is if your cigarette lighter works when your ignition key is off, the charger will work just fine. I would not recommend leaving the key on so the charger will work if that is what is needed.

Funny you should ask. I've used it on my 2002 911 (996) for a few years now. You just plug it in and leave it, no key. I run the cord under the door and close it, doesn't get in the way. Best money I've spent in years. ALWAYS starts as a new batt. Very convenient.

I have three cars on CTEK chargers for the winter. Mercedes CLS. Ferrari 360 Spider, Bentley GTC. The key does not have to be on in any of the three of my cars

Yes it works that way on my 1999 911 so believe it would on yours. Cigarette lighter is always "hot" even with key off.

I think it doesn't. I cannot start my car with this key. Well, I may miss something.

If you have an outlet that works with the key off, yes. The normal Cigarette liter style outlet does not receive power with the key off.

Yes, because most vehicles AC power or cigarette lighter ports are not hot or on when the key is not in it. But if you turn your radio on by turning your key to the AC on the car will not be on but the power will be and yes it will work then.

Thanks for the reply, I live in Central Wisconsin and I am planning on putting it on the oil pan of my car and I'm not sure if I should plug it in over night so it's warm by the morning because I'm not sure how long it would take to warm it up but I don't want to cause a fire either by leaving it plugged in over night.

I bought the key & the panasonic 2020 battery to make my key work, nut the battery did not work! There seems to be be some soldering involved with getting the battery to work so I still don't have the battery working. Once the battery works, you can take the key & cut it and then transfer the electronic parts to the new key & hope that it all works. I haven't had the time to play with the battery yet to try the key!

Your car has to be able to charge the battery that way so i'd check your owners manual just to be safe if you havent already. but we had a Toyota Prius and the ignition battery died so bought this and a quick jump kit. we jumped it from the cig lighter anytime the car wouldn't start. we never left it plugged in longer than to start the car. hope this helps!

Hi Jen, We have only used it plugged in. My husband thinks you can charge it and use it while charged. I will tell you it has saved us a towing expense on 3 occasions. Twice with a dead battery. So dead....it wouldn't charge. Once a bad alternator. We used the quick charge function and it worked like a charm so that we could get it to the shop. Good luck.

On the plug and play installation, its just plug and play. Some vehicles may require a relay which gets connected to the Battery.

did you plug in and then turn on key? or try key on and plug in. Does not however work on all cars.

Technically yes, the system runs on its internal battery so plugging it into the cigarette lighter will charge it. I found what I have to do is leave my Bluetooth on my phone in the "on" position all the time, and turn this off when I get out of the car. Then when I return to the car, turn it on and my phone automatically connects. A bit of an annoyance but it beats all the other wires hanging around and the feedback I used to get from them.

Depend on the vehicle you drive. some require the key turned on for battery to connect. Some have the battery connect directly. If you not use it for a long period of time, you do not have to run the engine to recharge your battery. But use it while driving or the car running is best. The 115v suppy is more stable

Plug something in while the car is running. Look for the light on whatever it is that you've plugged in that tells you it is being charged. Turn off the car and remove key. Is the light still on?

Yes to both questions. I have a 25-year-old Mercedes that loses charge probably because I don't drive it enough. I have the CTEK wedged in securely and permanently next to the battery and a short 6-foot extension cord that is tied-down so that the plug is accessible from the front bumper. I then use a 25-foot extension cord from inside the garage. I plug and unplug the Mercedes at every use ... it starts immediately even after 3 weeks of disuse. The extension cords are both household variety, and the connection has spent half the winter under snow.

If the lighter socket is still active when your key is turned off & removed then you should be able to plug into that socket. I don't use mine that way, I prefer to plug into an on board solar controller that I installed under my seat. On my pickup I decided to use a higher wattage solar panel, with a built in controller (Battery Tender 021-1164 10W Solar Charger). The controller are to insure that over extended periods of time, the battery is not overcharged, killing the life of the battery. For the small battery on my motorcycle and my lawn tractor, I've been very satisfied with the SP-400.

Make sure it is charged up and then connect the cables on each side just like you would jumper cables. If I remember right, you turn the switch on the back to "on" and then start your car. Works great!!

You should use cigarette lighter especially if your cigarette lighter turns off when key is out. The unit will then turn on and off so that you won't forget. Yes, it needs power all the time. The battery inside does not last that long.
