does this drain your car battery faster

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.

Your 12-volt socket is probably not energized when the car is turned off, so not an issue. If it is energized with the car off, this unit would put a small drain on the battery, so you would want to unplug it when not in use. Obviously there is no issue if the car is running.

No it doesn't. Your vehicle needs to be running to charge the battery. You may use it with your vehicle off but not for too long

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 recently gave this bad reviews only to find out that my battery was on its way out. What I have found is that if you have a good battery that has gone dead for some reason and is not totally drained this will jump your car off. It has also jumped of my Acura Mdx. If your battery is suspect and drained more than likely this will not jump the car off. You only get a couple of shots because with each try the schumcher drains pretty quickly. I hope this helped.

Yes, it will but the drain would be very minimum. If your battery is strong, I would not worry about it.

Depends on how is your cigarette lighter wired. Most cars need the key to be turned to "accessories" in order for the cigarette lighter to have power. Once you have power you can run the fan, how long depends on your car's battery capacity. If you run the fan too long you will drain your car battery. If you do not want to drain your car battery, then you need to run your engine in order to recharge the battery as the fan drains it. So for short periods of time, no you do not need to run your engine, if you want the fan to run overnight, then most likely without running the engine you will drain your battery.

No, all it does is give you an extra few minutes to leave your cabin lights on when it is freezing outside. Or it makes your starts in cold weather faster or easier rather than slow and struggling. It's really best for giving you extra charge when you leave your lights on in cold weather for a little too long, but it won't charge a drained battery. One of the great things as the previous person said is that it can charge accessories like GPS or Dash Cams without draining your battery while the car is off, I think for that alone it was worth it.

My battery was dead to the point of having to reset the alarm code. It took 45 minutes to put enough charge in it to start and let the alternator take over which is faster. Keep in mind this is a battery maintainer, so if you don't drive the car a lot it will keep it charged up.

Yes, it does. I plug it in the mid console outlet. But I understand that some car dash outlet is connect to the battery direct, in that case it will be constant on. 19000 hrs is a long time and I am not worry about. Even after that it should still run, but no more ion emit.

Yes, it seems to charge pretty fast. However, like I mentioned in the review it also seemed to drain faster if I used this charger.

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

it will but wont last as long, a slow charge is better for that type of battery, I got mine an charged it jumped 1 pickup [completely dead] an 2 cars [lights left on] a month later an still is half charged, I liked new type of battery in this, have gone thru a lot of other jumpers because left on battery I jumped to charge it, good luck, mines working ok. that's why it didn't come with cig plug, just usb plug.

I am not sure about this. It would probably depend on the the specific vehicle and its electrical system. I have heard that some manufacturers recommend removing the battery when charging it. I don't know if this recommendation applies to trickle charging/maintaining (like the BatteryMinder ). To be safe I would probably remove the battery unless you find information that states otherwise. Jim

There is a Battery pack called "T Power C" that can be used to provide power in lieu of draining your car battery. Google for the website. Could be available on Amazon of Ebay.

No, It will not drain your battery and just to be on the safe side its better to keep your car running. If your car has an old battery then run the goddam engine. If you are stupid enough not to run it while your battery needs juice .. Just call AAA !!! ERGO use common sense while you use electronic devises that uses electricity. Har har har !!!
