Does the fan turn on immediately as soon as you connect it to the battery/car, or does it turn on later as a result of getting hot?

Yes, the fan is turned on when you turn it on. I connect the inverter to a 12v battery and I hear the fan turn on.

Whenever the inverter is on the fan is on. This helps keep it cool. The more power you run through it the higher the fan speed, I do believe!?

It's pretty much "instant on" as it starts warming right away. At the most, 1 minute.

Yes. The fan runs after 100% charge as the unit then enters conditioning mode.

Yep, if you have the power switch set in the on position it will turn on right away, it also has a thermostat that will kick it on and off. Very nice little heater, puts off plenty of heat in a medium sized room

When batteries are in the proper position, it will turn on immediately. Use new batteries.

If it had a fan I think I would have heard it by now. I have never had an overheating problem, even when my car is in the sun.

It has a fan that requires attachment to a 12v battery source. We have it wired directly to one of the batteries.

It should turn on as soon as you plug in the USB. If it's not, the USB port might not be getting power for some reason, or it's just broken, like mine is. And honestly, it works almost as well without the fan.

Depends on how is your cigarette lighter wired. Most cars need the key to be turned to "accessories" in order for the cigarette lighter to have power. Once you have power you can run the fan, how long depends on your car's battery capacity. If you run the fan too long you will drain your car battery. If you do not want to drain your car battery, then you need to run your engine in order to recharge the battery as the fan drains it. So for short periods of time, no you do not need to run your engine, if you want the fan to run overnight, then most likely without running the engine you will drain your battery.

It has to be connected to a mostly good (more than 8 Volts) battery, or it won't start charging. What does the display say - any fault code ? Can you hear the fan come on ?

Mine got uncomfortably hot too while it was charging my truck battery back up. I set it on a brick and actually let a small fan blow on it (which surprisingly cooled it off) But after 2 days like that, it reached a point where it blinked green, and eventually went solid green. And once it went green it cooled off - presumably drawing far less current. I'd guess your battery is fairly depleted and must be given some time to charge back up. If you are concerned or feel it's a safety issue - call the company.

Not sure if that is normal or not, mine does not do that however I run fairly heavy loads (800 watts) so my fan will come on and stay on for 20 seconds or more until unit cools enough. If you are running a light load that may be normal.

It powers itself! Once you start the fire the heat will start hitting the copper probe and within a few minutes the fan kicks on.

as long as the car is running, don't shut off the car without turning of the heater.had it hooked up to a battery charger/jump starter only lasted a few hours

The temperature reading is basically instant. But I wait about 5 seconds to make sure. The battery is a button type and you twist the head off to replace it. I have not replaced the battery but looks easy.

Hi Bob, The fan circulates the ambient air. The car A/C should be turned on in order to achieve the best result of cooling. If you have any questions, please feel free to contact us.

The fan kicks on first at the programmed time. Then when it gets hot enough in the heat exchanger, the heat flows thru the vents.
