Thread: Power consumption of a xenarc? good ways to power it remotely/small battery pack?

The screen draws around 8 or 9W. The TS is powered through the USB port.

The power supply says that it is a 15W supply, but what do they actually draw? I read a thread that said 8W – 9W, does someone have a solid number from actual tests?

Are there any solutions to have a remote battery pack capable of powering the screen for a reasonable amount of time that is a fairly cheap solution?

Just wondering as I responded to a post about a ipod video connected to a xenarc, and was wondering if anyone had done this for a larger portable screen solution?

Since this is only for video, what would be a low power consumption screen solution that was not a touch screen or even vga resolution, as it really wouldn’t need it for this application I would think, and it is only composite/RCAs out?

Any cheap ebay solutions that are not going to fall apart in your hands first use, and are low/very low power consumption and at least comparable to the brightness of a xenarc?

Any ideas or thoughts?

HUH. WHat are you trying to accomplish?

The Xenarc, and most montiros will draw about 8 or 9 watts. There is no absilute answer to this, since everything that makes up the screen, every resistore, capacitor, diode, etc, is built to a tolerance, generally about 5 percent. So, no two screens are EXACTLY alike. And just because they are built with components that are 5 percent tolerance, don't think that the power consumption will sway 5 percent in either direction, because each component can amplify the other.

So, take it llike this, 8 or 9 watts, which is less then an amp.

I would think that a ps1 screen would work better for this type of hack

Not really looking to pin it down to a mW at a certain operating temperature, just wanted to confirm that it was in the 8 ish 9 ish range from someone that has actually physically tested it (hoping that someone had done some research in the area of system consumption) and had actual data.

Trying to find out if anyone has ran a small LCD such as the xenarc or other small LCD on a remote battery source such as NiMH?
And hoping somone had some insight about the topic they could share.

I have seen some AA size 2700s floating around lately, that would make a smallish light weight pack.

I have a 700TSV which adds about 900mA to the current draw of my PC when it is turned on. That would be accounting for both the 12V to the screen and 5V for the USB touchpanel. So that would be in the 10 Watt neighborhood.

I don't think anyone would know what yours will draw based on the info you have given so far. Bigger or brighter screens are going to need more power. What you got?

Why don't you get a battery powered DVD player and be done with it?

Why don't you just buy a factory gps/mp3 unit and be done with it?
