Does it have a built in battery to continue to run when the car is off?

No. I put in ice packs with my food. I unplug it when the car is not running and everything has stayed cold for at least 4 hours with it unpluged. The ice packs are still frozen and just a tiny bit soft.

No. It keeps drawing off the car battery until you unplug it. I got the 120v adapter so I could plug into wall outlet or extension cord.

It doesn't have either of these. You also have to turn it off and unplug it from the the vehicle otherwise if it sits to long plugged in you will have a dead battery. Other than those things it works great.

Yes, it does. I plug it in the mid console outlet. But I understand that some car dash outlet is connect to the battery direct, in that case it will be constant on. 19000 hrs is a long time and I am not worry about. Even after that it should still run, but no more ion emit.

Yes, it has a built in battery (non-replaceable). Runs several days on a single charge. Works very well so far (9 months).

Battery power goes directly to this unit. If the fan stays on when car is off, you need a new one. This is what happenef to me.

It does. However, there is no way to turn the unit off without taking the battery out, so it runs down fast if you don't remember to remove it.

Yes. It turns on and off automatically whenever the car is turned on and off (and continues recording).

Well, when you are driving, you alternator will charge the battery, and the draw is small, so there is no issue. It does have an auto shut off, however.

Yes, if you use it with your car turned off. As long as the engine's running your battery won't be drained.

It does not contain a battery at all so never is charged. It must be plugged into the 12V socket to run. It will not drain your car battery if left plugged in while the vehicle is turned off. You simply plug one end into the 12V socket and the other end (1/8" jack) into your audio device. Then you tune and it works.

Short answer: no. If you leave the car for longer periods with the camera in parking mode it may drain the battery preventing the car from starting. I would recommend that you get the discharge prevention unless you hook the camera up to a connection that does not have power when the car is switched off.

most cars have the 9v outlet tied into the ignition, so it's not powered when the car is not running. Therefore, it won't drain your battery at all.

That would be my big problem. If your car doesn't turn off that plug when the car is off it will stay on and run your battery down. So I've had to have my car jumped a few times when I forgot to turn it off. And that's bad for your battery.

It is battery powered -- 12V car battery. It could be modified to run off any 12V constant DC power source.You couldeven cut a on/off switch into the circuit (a weak point for the unit) You must unplug the unit to take it off power source.

No - the car does not need to be on to operate the inverter. As far as 'runtime' is concerned, two factors are important: A) the draw from the connected device and B) battery capacity. You can likely find runtime information and calculation formulas on the manufacturer's website or via a web search.KEEP IN MIND that car batteries ARE NOT designed to be constantly drained (it will affect long-term battery performance), so it would be best to periodically run the vehicle to prevent the battery from running down too far.

No. It runs on battery power which is recharged by either solar or hand cranking.

No it does not. You program your vehicle while it is off and follow directions on screen. Unplug it when done.
