Powering 30 Watt Monitors, Possible Without Generator?

[Robertofish]

So I have been looking at Generators to use to power 21 inch Monitors that have HDMi inputs, the power consumption of each monitor is rated at 30 watts since they are led monitors, what I have found is that with my boom mic, any generator including the Honda Inverter Generator EU2000 Watt is way way to loud there is no way I would be able to use that so I have gone back to the battery powered option of lighting kits etc, my question is if the power consumption of a monitor is 30 watts but its a 2 pin or 3 pin power plug is there an adapter that I could use to make it compatible with some type of battery? For instance if I were to get NP1 type batteries could I use a 4 pin xlr to 3 pin power adapter because my thought on this is that 30 watts consumption is very little and if something like an NP1 is rated at 60WH that means 2 hours of usage when using this type of battery if there was the correct type of power in place.

The question is really the type of power input. Yes, 30W is not too huge and your 60W battery should run it for something approaching two hours (likely closer to 1.5 hrs. as batteries decay towards the end). But if the input on the monitor is for 110v AC power then your 12v DC battery won't do anything. There's a transformer in the monitor because in general the internal guts of the monitor is likely running at 12v or something close to it, but unless you have the access to input to that directly it won't function.

You can look for a monitor that uses a "wall wart" power supply and then look on that power supply to see what the output voltage is. Often they will be 12v out. If so then you can make a cable that plugs into the power input on the monitor. You can also look for a monitor which can run off power from a car. This is a 12v input and there are ready-made cables available to convert this connection to a standard battery.

Any suggestions on monitor in that case I am looking for something that is not a field monitor I already have those I am looking for something bigger something within the 15-20 inch range, just to clarify you are saying it is not possible to use a battery to power a monitor with standard power plug? This is the monitor I am looking at right now

Its 1080p and uses only 30 watts as stated above it should work for what I need as long as I can find a way to power it via battery. Its also very inexpensive.

Yes you can power something like that with batteries by using a sine wave power inverter.

[Robertofish]

By that do you mean a generator? Or is that something else? Where would I get a sine wave power inverter?

Any suggestions on which one to get or does it not matter, it needs to have 4 pin xlr inputs right?

Will this work for what you are saying? http://www.bhphotovideo.com/bnh/cont...st&sku=416803?
