Is there a power button on the inverter? Or is it always energized when the car is running?

No button. But you can always unplug it from the cigarette lighter. This is just an inverter. It means it just convert the car power to a regular 110 V, so it's not like it's being charged up or something

I'm not sure what you mean. If you're asking if it will still work without the car being either on or on accessory, every car I've ever been in does maintain power to the cigarette outlet even when the car is completely off. If that doesn't work, just turn your car on accessory and it will work fine. You just turn the switch on the invertor on. I'd recommend turning the interior lights off in your car while doing this or run the cord through the window to prevent running the battery dead. If you do that, you won't have a problem with your battery going dead, not even close.

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.

yeah, you can buy an inverter. an inverter turns the 12volts DC from your car into 120volts AC(the same as a normal house outlet). here's an example of an inverter: Xantrex Technologies 851-0178 XPower 175-Watt Micro Inverter just make sure that the inverter is strong enough to power the cushion (look at the WATT rating)

The Buton on top is a power switch. But I prefer to keep mine on as it does not drain my car battery when the car is off. Also, the MPOW is not battery powered and turns off when you turn your car off. All in all WELL worth the the price!

If the battery is not charging, the inverter will slowly drain the battery, even if the inverter is not in use, when the inverter is turned on. However, you can turn the inverter off with the power button on the inverter, and leave the inverter hooked up to the battery without drain, as far as I know.

it will provide power until its source of 12 volt power dies, i have run mine all day day in day out for a year in harsh environment it powers my laptop, big printer, internet and phone chargers, air compressor at times, (run a direct connection with fuse to your battery for best results), use caution as it will warn you of low car battery but it keeps running and will kill it (my truck has 2 batteries). it is a great inverter, no problems

Your 12-volt socket is probably not energized when the car is turned off, so not an issue. If it is energized with the car off, this unit would put a small drain on the battery, so you would want to unplug it when not in use. Obviously there is no issue if the car is running.

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

Yes, there is a power button on the top. It has a fairly good battery life when charged but you'll need a charger once its depleted. But there are many times I use it without plugging it into the car.

I believe you will need an inverter to change AC to DC. Unless you have a factory or 12v outlet installed in your car.

Mine stays plugged in with no problems. I do not believe there is any significant power draw unless something is connected to it and is continuously drawing from the invertor. Then that depends on the rating of the vehicle battery rating or reserve capacity and the load drawn from the invertor, up to 120 watts.

No. It is a good inverter though. Some inexpensive inverters will use a lot of energy even if they have no load on them. This one doesn't. Very important when running something that cycles on and off like a refrigerator.

No, the power is on the control panel. I wired mine to a switched line, but it still needs to be turned on every time from the control panel.

MaryT are you sure?, On my unit the Power light is on all the time wether I am charging my car or not.
1159797
Yes. I have mine in my center console and I never touch it. I just get into the car, turn it on, and it's connected. I don't even think there is a button to manually turn it on or off.

Yes, at 13.8 volts DC when your car is running. With engine off battery voltage is lower and so less power.
