Can I use this with a fully charged car battery that is removed from the car. Does the car have to be running? I need it power a simple 200 watt movie

I would like to know same: if used with car battery that is in the car (not taken out), does the car need to be running????????? Also, does anyone have an estimate of time it would take to charge?

Please note that car batteries are for starting: a high load for a short time. It will work with an inverter but will be ruined by low load over a longer period of time. For anything other than occasional use you need a "deep cycle" type of battery.

It is not battery powered. It must be plugged into AC at all times. I suppose if you were really motivated, you could make a DC power supply from a car battery or two, and a DC to DC converter, but that's beyond the scope of this reply :-).

Yes, you can. It only needs a 12 volt power source; which your car battery is.

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.

If you have an AC outlet in your vehicle you should be able to do it. I would recommend having the vehicle running, so as not to drain your battery. It only operates on AC.

I only use mine with an adapter and plug it into a wall socket. I you leave it plugged into your cigarette lighter and the engine isn't running, it will run down the battery. My cigarette lighter doesn't have power unless the car is running, anyway.

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

You would not want to use a "car battery", you should use a deep cycle battery often used in RVs. If you are considering the 3000 watt unit, you would need more batteries to sustain the load for an extended period of time. I use 4 deep cycle 6 volt batteries in a series/parallel configuration in my RV for providing power without being plugged or running the generator. As mentioned in other comments you will need to keep the battery charged until you need it.

there's no need to power it from a vehicle--it has it's own rechargeable battery pack which can be recharged using the included 120vac adapter. Why would you want to plug it into a cigarette lighter?

I havent tried it myself, but I would to say-Yes it can be powered by a 12v car 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.

I would recommend getting a electrical charger. This one is more for something that you don't drive very often like a atv or a lawnmower. This only being 2.4 watts, isn't powerful enough to charge a car battery. It's really just for maintaining. I bet it would take a long time to fully charge a car battery.

Yes, but the power supply provided is for a normal 110 outlet. You can just cut the transformer off and attach it to a 12vdc supply in your car. I put this in my van so I could see left and right side rear view cameras on one screen

I have never tried that. I do not think it could start your car. Maybe slow charge your existing battery if needed.

Yes or you could use other 12v socket in the car, it's actually better than hooking up to power directly ..when you turn of the car it turns of the monitor.

I own this unit. It has relatively modest power needs (less than 100w), but power is used for more than just the electronic ignition. There's also the electronic control system and an active venting system (i.e. a fan) that uses electricity. You could easily power this off a small generator or a battery system when in use as long as it can provide stable current. (Note: I have no idea what the warranty states about running it off a battery, so do so at your own risk.)

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.
