Does this drain your car battery

It doesn't seem like it. As long as your engines on the alternator should charge your battery and everything should be fine.

It should not drain your battery while your car is off unless you cigarette lighter socket is wired to your battery instead of a accessory fuse. Many cars before 1992 were like this. You could get it rewired, probably for under $20 depending on your location, or DIY, if this is the case. It shouldn't drain the battery very fast though unless you have an already bad battery.

It hasn't done this to mine. I am fully satisfied with the one that I bought.

My Subaru does not get drained , really depends on the electrical set up of your car.

In my experience, GM cars don't cut off power to the cigarette lighter when the ignition is off; whereas, Toyotas and Nissans (and I'm sure others) do cut off power to cigarette lighter plugs with the ignition off. Whenever the adapter is plugged in, this device uses some relatively small amount of power to illuminate the blue LEDs; I'm not sure how much power the blue LED lighting uses, but I'm sure it's not too much.

I have a small compact car & I use this adapter all the time & I have not had any issues with it draining my battery.

if the blue light stays on with key off - it will drain battery - if blue light goes off - then you are only "hot" when key is used

No. All positive connections to the start battery remain the same, but you can move some accessories from the start batt to the aux batt so when your alternator is not running and you are using accessories, it will not drain your start batt. Hope this was helpful.

I can't say definitively but from empirical evidence I don't believe it does. The head unit goes dark when the car is turned off and I've never experienced a battery issue.

It depends on where the OBD connection is in the particular car whether the actual GPS device can be seen. You'll have to check your specific situation. No, it dies not drain the battery at all.

Yes, it does work. The disadvantage is that you have to leave it plugged in all the time. If the plug is in an inconvenient place, you may hit it with your knee or other body part. Also, i'm not sure whether it uses power when the car is off. If it does, it could drain your battery over time.

Yes, it does both jobs. I have one car that is driven short distances, it's battery may not have time to fully recharge. I connect it to the Battery minder every night, to keep the battery at a fully charged level. I also use a second battery Minder for an old car that is rarely driven. It keeps that battery at full charge, so the old car starts quickly, every time.

No the charger won't drain the battery -- Nor will it maintain it... Batteries will naturally slowly lose their charge while sitting unused -- Plus sometimes dependent on where the batteries are being used (boat, Car etc.) there might be a slight discharge to circuit leakage . clocks, lights, and the like. Just plug your charger back in a day or two before you use the vehicle .

If I charge this and leave it in my car, as back up, will it drain faster under particular conditions?

Assuming your car doesn't send power to the 12v outlet when it is off (and most don't) it won't drain your battery. I left mine plugged in until it died and never had any issues.

most cars have the 9v outlet tied into the ignition, so it's not powered when the car is not running. Therefore, it won't drain your battery at all.

NO, it will remain on and drain your battery.BTW, do yourself a favor and dont buy this piece of &%$·!!%$I cant even sell it. Sucks bad!

Yes, the device will automatically shut off when the car is turned off. You will never have to worry about it killing your car battery.

No it does not. But my cheap dollar tree batteries have not died yet after a month of use. So it doesn't drain them fast either.

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 don't connect it to constant because it could drain your battery. I rely on the back up battery when the car is off.

It shouldn't be excessively draining it. My battery is pretty old and I've left my truck with this same unit in it armed for days at a time without starting it and it was fine. I would have the vehicle battery tested first (most auto parts dealers will do it for free these days)

It stops charging your battery when the battery reaches full. It does not drain the battery prior to charging. I use mine for my 14.4 B & D tools. Does the job it was intended for. Hope this helps.
