does the car have to be running to work

No, but it had to have a charged battery. Just turn the ignition key to the Accessory position to bring power to the "lighter" socket.

Not necessarily, but the pump does draw a substantial amount of current, so you should not run it for very long without the car on. I'd recommend having the car running if possible/safe, but again, it doesn't HAVE to be on. -James

No , but I would recommend it , as it will drain the batt if you use it to long , as that has happen to me ,

Not unless you want to. It runs off the car battery as supplied through the cigarette lighter (accessory power outlet). Depending on he vehicle, you may have to have the ignition key turned to the on position to have access to battery power, but you don't necessarily have to have the engine running. I would only run the engine if your battery power is low or if you're going to spend forever inflating multiple items.

It is controlled by a thermostat and really doesn't need to run unless heat builds up. If your roof can get to 85 degrees when it is 0 outside then yes it will kick on.

Yes, it needs to be plugged in to your car's battery directly, or your car's cigarette lighter, while the car is running. It comes with cables for both. it does not store power, as it does not have its own battery.

Hello, Yes you are able to run it where ever power is. If you do, you might need to look at if your lighter is continuous power or does it shut after you shut the car down. but either way Answer is yes.

Sure, if you wanted to. You'd just need to wire it such that it has constant power while the car is running.

The unit is not AC powered it is 12v DC it has two wires you just connect into your power system after the ignition switch so it comes on when your car does but the screen doesn't actually run until it received a signal from for example a back up camera.

Unit is AC(house current) only but would probably be ok if a car had an AC outlet and you kept the engine running.

Plug something in while the car is running. Look for the light on whatever it is that you've plugged in that tells you it is being charged. Turn off the car and remove key. Is the light still on?

Yes, unless you wire the fan wires to a switch, or install an in line thermostat (Sold on Amazon), or have your mechanic wire the fan wires so when the engine is turned off so is the power to the fan meaning don't have him/her wire to run directly off the battery. Hope this helps.

No. There needs to be a controller unit between the power outlet and the car.

Yes . Has to be connected to power output with power only when engine run .

Yes I leave it plugged in all the time but of course when the car is off it is not providing ant power.

Are u asking with a system running with the engine off or the battery just sitting there not being used in the car?

Most cars yes they will need to be on. Some cars have accessory ability when turned off.

I just turn the unit on before connecting to the tire - that way it's not under a load when you turn it on. Vehicle does not need to be running.

Not sure understand question but there is a circuits breaker. Like an outlet should be on all the time. Not using power unless plugged into your car. Hope helps.
