Does it draw any power when "OFF"? My 12v power source is a battery pack (8 AA batteries) and I don't want it to drain if left connected.

I have not check that point out yet as soon as I get home I will have to check that .

I do not believe so. . If the LEDs are totally off it should not draw any current .

I'm not positive, but I believe when it's knob is in the off position there is no power flowing.

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.

The power is charging the base. If you unplug it, I imagine it will work only until the battery runs down.

Yes, the USB charging circuit in this outlet does use power even when nothing is plugged in. I tested by wiring a Mastech MS8264 digital multimeter in series with the hot lead that powers the outlet. With nothing plugged into the outlet, the multimeter read 0.42-0.44 milliamps at 120VAC. Note that this is not a true-RMS multimeter; the actual power draw was probably more like 0.66 milliamps. That's less than 1/10th of a watt, which might be so little that it doesn't matter to you, but it is definitely nonzero and does add up over time. My review contains some more details about power draw:

The standby current draw is slight, so leaving the inverter on when it is not supplying power won't significantly drain the source battery over a period of a few minutes.

in reality it draws about 30 watts dc or about 2 1/2 amps dc i turn it off when not using it.....

It draws very little current. I have driven 2 off usb power. If running from a micro controller such as an Arduino, you will need to connect to 4 I. O. Lines and 5v and gnd. Do a search on Google. There are plenty of tutorials on running it as well as some libraries that can be downloaded.

It does not use any battery. It connects to your source and the power is derived from your source i think.

In the absence of a glow plug connection, the circuit is incomplete and no load is present to be powered by the attached battery. So the answer is "no" current draw is zero.

It does draw a lil current as long as you have 12v and about 3.2amps of current ur good i have it on a 5 amp fuse and it has never blown. It does use about 32 watts. now this is just what i have clamped it useing at run not fire up. Hope that helped

that's what I am doing - here's what i am finding...the control item (using a kill-a-watt) is still drawing .005 amps when everything else is off...i know this is practically negligible and in the scheme of things it's not really gonna matter money wise, just led me to the question that if the most least power consumption device (i.e. -0-) was the control item there would be absolutely no draw whatsoever. Thank you for your replies and if I am completely off base, please let me know

No once the unit is fully charged from the mains it will power any apliance & recharge via solar power how ever if the unit is drained completely it will lock down & will have to have the mains adaptor connected even if for only a second to re activate it beare in mind the solar panel trickle charges the unit & cyan take 24 hours of direct sunlight to fully recharge the unit but it will replenish its self slowly during use I find about 5% of the power out put comes from the solar panel wen used in direct sunlight but don't quote me but it is a excellent product & I can't leave with out it please not as with all rechargeable batterys the battery capacity will demimish with time if the unit is allowed to be fully drain to point of auto shut down but if left in sunlight it will recharge itself I sue mine when traveling at night & let it charge during the day hope this helps

I have it plugged in to a 4 way plug which in turn is plugged in to my only available port. I have 2 other things plugged in to this also and have had no battery problems. It states that it is 12V. I don't know if this answers your question or not. My car (2011 Honda CRV) automatically shuts all power off to the charger when I turn the car off so I have no worry of battery drain.

I have tried it both ways, but it always seemed that when I left it unplugged and needed it, there was no power. Now I leave it plugged in all the time. However, probably like other devices of this nature, it might be a good idea to let it run out occasionally and recharge.

Yes, if you use it with your car turned off. As long as the engine's running your battery won't be drained.

It doesn't draw power. It has an internal battery which is charged with a USB cable and supposedly lasts 6 hours between charges. Haven't had mine long and haven't used it enough to know if it really lasts a full 6 hours.

Its been my experience that leaveing it plugged in after dark the charge likes to feed back through the carge controler and heat up why i dont know but it does i would reccomend unplugging it as soon as it gets daark just to be safe..it does get kinda hot!
