When plugged in does it continue to draw power and possible drain the battery?

It won't drain the battery while the car is running. Most cigarette outlets will shut off within minutes after the car is turned off. Or you could do what I did, buy the hardwire kit and wire it so it comes on when you start the car and shuts off when you shut the car off. Total cost thru Amazon fifteen dollars, and twenty minutes to hook up.

I'm a mechanic and yes it will drain the battery if you leave it plugged in while the car is off, my suggestion is to hard wire it into the car with an "add a fuse" , it's simple and cheap and will turn on and off with the car without draining the battery (look up a video on YouTube "how to hardwire in a radar detector")

I think that depends on the car, some cars turn off all electrical function when off and some stay on. But as long as the car is on you should be ok.

If it is turned on (lite on) its drawing power ...minimum but drawing power...plug it in a power outlet (lighter) that cuts off when key is off

And depending on the year of the vehicle the cigarette lighter will turn off when the car is shut off but in most cases to be safe rather rather than sorry you should unplug it or hardwire it in.

That has never happened to me, so I can't answer specifically. However, if I unplug it, it must be reset again, so I assume the same would be true of a power failure.

Yes, it should turn red when you plug it in. Don't leave charged bateries in the charger with it unplugged, or they will drain.

It shows that the power is successfully connected. It goes out but never lets you know when fully charged. Sorry, I just let it go for a few hours.

I let my laptop run on battery and when it gets too low plug it back in. I have had this battery for about 6 months and have had no problems. My last battery gave out because I kept it plugged in all the time.

It Doesnt. You will need to unplug it or else your battery will drain just like mine.

Absolutely not. Unit operates when plugged . Once you unplug ,if turned on ,starts operating using the batteries.

I have left it plugged in for a day or two, but not consistently. A day or two didn't seem to hurt it.

Mine does the same thing. It is charged when I unplug it later. I wish the LED indicator would stay on.

I believe this is normal operation. It did that for me with the original power supply. I think it's just to let you know when it's charging vs. battery mode. Hope that helps.

depends partly on what you have plugged into it ... without anything plugged into it i would estimate it to be pulling amperage about like a cd player ... with a laptop or something plugged in it will drain your battery even faster

Yes, it is permanently connected to the batteries and doesn't discharge them when not plugged in. However the whole point of the thing is to keep it plugged in during storage so the batteries don't self-discharge and degrade.

No, don't leave it plugged in. It will drain the battery. The green light is cool but it drains the battery slowly but surely.

Have used plugged in no difference noticed in power noticed except when low battery...

As like anything else that doesn't have an auto shut-off, Yes, it will continue to use Power while charging at the same time!Always remember to turn it off!It will still charge, but, it'll take quite a bit longer with it on than off!I hope this clears things up for you.

it shouldn't drain the battery, only draw a few milliamps to keep the light lit. if you have a weak or old battery you may want to unplug it to be safe. I leave mine plugged in all the time & have had no issues.

It only draws current when a device is plugged in and using the USB power. You can leave USB cables plugged into the ports and the outlet will not draw current until those cables are connected to a device that attempts to use the USB power. (In theory a device could stop using the USB power once charged, and the outlet would no longer draw current, but very few devices are designed this way.)
