Does this device draw any power when it's not timing something? I would like like to use it with a battery and don't want the battery to run down.

Yes, it does. While minimal, It has a red LED that is powered when ever power is applied to the unit. You need to apply power to the unit in order to short the two leads. So for anyone hoping to use this with a battery, a typical 12v Red LED consumption is .01 amps. That's 1000 hours on a 10AH battery or 40 days. It's a shame, the device is great otherwise. The jumpers control the time. S4, S1 and S2 combined with the pot control time. There doesn't appear to be a jumper tied to the LED.

no power draw that i'm aware of, the unit is activated when triggered by an outside source.

Absolutely not. As long as the device is 12volts it will only draw power from the battery as needed. In other words you can hook one of said devices to the battery or many.. the only thing that will change is battery life.I love mine.. and I use it to power anything from 12v cameras to 12v led's to 12v lcd monitors. From 0.2A all the way to 4.5A

Try running something not as power demanding and see if it works. Do you have a multimeter? What type/capacity battery is it? How are you charging the battery?

It draws almost no power while it's sitting still. After 30 minutes of no movement, it goes into "sleep" mode drawing only enough energy to wake up when the care is moved. Our vehicle has only sat for about a week but there was no noticeable effect on the starting power of the battery.

Yes you can use it when the battery runs down. Under those conditions, I have just plugged in the cord and it runs fine.

No. Nothing I have found would generate enough power that runs on batteries.

Yes, after a charge it runs without being plugged in, it works both ways. I just wish it had some sort of light to tell you when it needs charging and when it is charged up.

Yes, it draws 15 MA when connected. It is not necessary to disconnect unless you have a small battery.Best Regards,EH

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.

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.

It will deliver power to a load all the time. You just want to make sure that the charging rate exceeds the draw of the load over an average 24 hour period or the batteries will eventually run down.

This device is not contain a battery. So you will need a fixed power source.

This would depend on the battery it's hooked up to. The inverter would have no trouble with the power draw you mentioned, but to calculate the time go to: http://www.dcacpowerinverters.com/faq.htm

Nope, it doesn't provide power. It works for my purpose but really doesn't add much value in my opinion.

I don't believe the amount of power needed makes any difference. It just acts as a connector between the power cord and the outlet, if that makes sense. So it connects them and cuts the circuit on and off at the designated times. I've been using mine constantly for several months now and it still turns on and off at the exact times I set it for.

YES. It draws no power unless a device is attached. Cables only attached drew no power. I used a Kill A Watt to confirm. Hope this helps.

Yes, the control device draws the same power as if it were plugged into the wall directly. For example, in my case my receiver is the control device, and operates in standby mode when I turn it off.
