My car has a specifice convenience port to keep the battery charged. Otherwise the convenience port in cars may dissconect if the ignition is off. That will have to be determined on the car’s specific wiring. There are indicators lights to give an idea of the state of the battery which I didn’t find very accurate.

Easy way to hook up your charger, This little adapter along with the cord and the SeaTac charger is a perfect situation for my 911 S

If you have a CTEK charger for your car, using this handy adaptor means you don’t even have to lift the hood. Just plug the charger into the adaptor and the adaptor into your 12V / Cigarette lighter and you’re charging!ONE NOTE OF CAUTION: Check to make sure your car’s 12V works even if the car is turned off. (not all do) To be sure, turn your car off and then plug your phone into the 12V. If it starts charging, you’re good to go. If you really want to make sure, leave it plugged in for awhile and make sure it has fully charged the phone.So much easier than connecting the charger to the battery.

Already had the C-Teck 5, but I was lifting the truck to install every time. Now, I just “plug-right-up” in seconds. We love it.

I have my cars on battery tenders. I wanted to take the car off the lift so I unplugged this piece from the cigarette lighter and lowered the lift. Unfortunately, this piece went under the lift ramp and was crushed, so I needed a replacement. Lesson learned: check where the part is before lowering the lift.
