I have couple of NOCO Genius battery maintainers and also an old Battery Tender Plus. Recently, I purchased a NOCO GC003 accessory (pic below). I have the battery maintainer mounted on the wall right next to my Jeep.

I drive into the garage, open the driver side window, reach out and plug this to the "cigarette" lighter in the center console because it is always powered even when the Jeep is off. I don't need to open the hood using this accessory.

I like this. Please elaborate because I'm not the sharpest knife in the drawer when it comes to electrical systems in cars. Are you saying that with this "cigarette lighter adapter", you are charging your battery, by reversing the flow of power through the cigarette lighter port, back into the battery?

Does this effect the operation of the charger in any way? By that I mean will it still sense a full charge and go into "Float Mode" the same as if you were charging from the jumper posts?

That is correct. I am using the adapter to keep the Jeep's battery charged. I use this with my NOCO Genius5 battery maintainer. For the adapter to work, the cigarette port MUST be an always powered one. If not, you plug it in before it loses power. That's what I do on my wife's Cayenne. The maintainer will charge the battery and go into "float mode" once charged. Same as using the jumper posts.

Hope this answers your questions.
