Is there a way to keep things charging when u turn the car off through 12v or USB?
None of the Cruze have this capability... anything you want charged while your car is off would have to be some sort of aftermarket device you would install. I don't know of anything, but I'm sure there is something available.Is there a way to keep things charging when u turn the car off through 12v or USB?
Strictly depends on the load and the size of the battery, generally speaking anything plugged into a car port and charging is drawing a miniscule amount of current at batt voltage or lower so the total power usage is small.What is max time one could keep charging device(s) in the car until the car batt dies? ?
Fuse sizing can limit current, some cars have a timed delay before switching off power. Killing a car battery with the typical device that would be charging in a car (phone, ipod, etc.) would be quite the feat, for multiple reasons: lower power usage relative to batt. size, charge controllers in the device (if the device is off and charging is complete current flow will be minimal).How do the premium cars that have car off charging capabilities do it without killing the car batt?
Thanks for taking the time & for the answers.Strictly depends on the load and the size of the battery, generally speaking anything plugged into a car port and charging is drawing a miniscule amount of current at batt voltage or lower so the total power usage is small.

Bottom line is you wouldn't have enough time on your hands to kill your battery with your iphone or similar device plugged in, even simultaneously.
If you are running an inverter for some reason then that would be a different story but I dont think that is the case.
Hope this answers your question.
Not the conclusions I was trying to draw...you don't need a high quality charger to prevent your car battery from draining or to stop the charging cycle - most won't, in closed loop form, control charging. However the laws of physics are usually on your side... if there is no difference in potential voltage then there will be no current flow, so inherintely once the device battery voltage approaches supply voltage current should "trickle" at such a slow rate that there is no value to speak of a car battery draining as a result. Ironically this is a moot point because all modern devices have battery control logic built into the software/hardware that monitor and control charging based on a number of factors.Thanks for taking the time & for the answers.
So just to be sure... check that you have a quality charger(s) & not some real cheap one that has no logic to stop the charge cycle after the device(s) battery is full. Turn off your device if you're charging with the car off & in any event monitor the length of time you're charging devices with the car off or you might risk draining the car battery.
This is incorrect. If there is no current flowing through the device then it won't drain the battery. There is no such thing as a power outlet that is on with nothing connected. Are you referring to if he left something like a car charger connected to the cigarette lighter? Some of those will pull a slight amount of current for the LED light with nothing connected, but not enough to drain a battery unless the car sat for weeks. The cigarette lighter itself cannot drain the battery even if it is hooked up to constant 12v as there is nothing connected the power and ground wires for current to flow.A power outlet thats ON, with no device connected, uses just as much power as a power outlet thats OFF, with a device connected.
No, it doesnt drain the battery, if there's no device connected to it.
I think I figured out a more elegant solution which invloves moving 2 wires in the interior fuse block. If I can devise a release tool at lunch, I'll report back. It looks pretty easy though. Haven't had enough time to jack with it this morning. If it works, it will be fused in the fuse block and will not involve cutting any wires.OP-You can solve this problem by finding a constant 12v source or running a wire directly from the battery to the cigarette lighter. Remove the colored accessory wire from the cigarette lighter, tie it off, and connect the constant 12v wire.
