Will use of this cord from the JNC 660 to the vehicle's cigarette lighter socket preserve computer memory while the battery is disconnected?

It can be used for that if you keep the ignition switch in "acc" position. However, be careful not to let the + terminal disconnected under the hood touch ground because that will short out this battery connection that you've made.

This cord is used to charge my battery jumper. Not to keep your car memory.

It will plug in to a computer port and probably will in vehicle as long as the vehicle has a usb port plugin. It will not plug in to a cigarette lighter plug in vehicle. It will also plug in to wall outlet as long as you have adapter for it.

Yes. I have been using mine like I use my laptop - just plug it back in no matter how much has been discharged.

No, not unless your cigarette or power port is only powered with the engine running. But it's a moot point because a large power unit such as this needs to be wired directly to the battery. It can draw way more power that the fuse or wiring of a power port can handle.

not many cars power plugs work with engine off so no risk of draining battery , power cord usually plugged in and used by someone in the car while driving

I had purchased a Duracell inverter along with this...connected the inverter to the cars cigarette lighter and then this power surge at the other end. My Dell laptop worked fine with it. I'm assuming Macbook Pro shouldn't be any different as far as power supply is concerned.

Yes it will just put your power wire with a split goin to a fuse in your fuse box on the driver side so you dont lose your set stations as its for a memory connection

probably though I haven't managed to find the cable anywhere. I left it plugged into the lighter (Auxiliary power outlet) and it kept running until it drained the battery.

Yes, if your car's cigarette outlet stays powered on when the car is powered off. The camera goes into a sleep mode where it only turns on when it detects motion to try and not drain your car battery. You can change the sensitivity of this feature. If your 12V outlet turns off with when your car turns off, then you will need to rewire the outlet a little or just wire the camera directly into the car's battery/fuse box. Another thing to note, my battery was getting old and alternator was apparently failing.... so leaving this plugged in without turning the car on for an entire weekend drained my battery to the point were the car would not start Monday morning. My boss was not pleased when I was late to work, trying to get a jump from my kind neighbor. Replacing the battery and alternator, I have not had this issue again. Just a warning, it does drain some power.

None. It plugs into your cigarette lighter socket. How you handle the light connection on the tow vehicle for break and turns is up to you.

no, plugs into your lighter port. unless your lighter port does not stay on if your is not running.

Mine did not, however, if that was what I was going to do with it, this is what I would do. Connect it to the 24v battery under the hood, then run an extension cord through the firewall under the dashboard. Once installed (very easy) you never have to mess with it again, and it won't get lost when you are not using it.

Yes. For longer life of traffic USB just don't wind the cord tightly for storage.

If your DC battery is dying and you plug your computer in to AC power using the power cord adapter, the computer should not shut down unless it has already initiated shut down safeguards. Once plugged into a wall outlet, it shifts to that power source and starts slowly charging the batter as well.

I only use mine with an adapter and plug it into a wall socket.I you leave it plugged into your cigarette lighter and the engine isn't running, it will run down the battery.My cigarette lighter doesn't have power unless the car is running, anyway.

yes!,suggest you disconnect negative battery terminal during storage to preserve life of the car battery. charge jumper pack to 100% and connect cables. charge battery pack every other month to keep it ready to go

Yes. This cord is useful for a portable cooler that can be plugged into the cigarette lighter receptacle in your car while you are driving, and then connected to the male cigarette plug in the cooler in a motel while the 110v is connected to the wall socket. We have used it many times so as to keep medications and food cool while on a trip.
