Will it drain my car battery if left on while parked overnight or while at work?

I just went through the manual and it doesn't mention power draw. However, the unit has an internal battery that supplies power until it runs low and then draws power from your vehicle to charge. There is a small blue/red light that displays what it is doing. During the set-up you can program the unit to shut off automatically after some period when you stop or leave the vehicle. It will automatically turn back on when you next start the vehicle. Plus, the on off button is readily accessible. This unit is so small I can't imagine it running a car battery down even if left on for a lengthy period (not programmed to auto turn off).

No it will not drain your battery it isnt that powerful But if you're worried about it. Inside the menu you can set it to turn off anywhere between three to ten minutes. Set it to motion detection that way it'll only come on when the car is in motion.

I have left mine on overnight and it does not appear to have drawn down the battery

It depends on how your car is wired. If you have a iPhone charger for your cigarette lighter, try charging the iPhone while your car is turned off. If it does, then yes anything you plug into that outlet will drain the battery when the cars off.

Well, I believe that anything using power from your car battery will drain it over time but I have used this product for up to 45 min with the car off and not have a problem. I wouldn't recommend doing it for extended times though. Yes, it works without the car being on.

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.

I'm not sure. I knew I was going to use it the next day, so I put it on the charger overnight. The next morning I blew everything out of the rain gutters, and blew off the driveway (large enough to park 8 cars), and blew off the garage (oversize 2-car) floor. It still was working, but I was finished. so put it away and put the battery pack on the charger.Rich

Depends on if the 12 volt outlet is constant or switched. If it is always on when the car is off and you will be away from the car for more than a few hours it should be unplugged as it has a minor current draw.

As long as a device is not actively pulling electricity through the port, then there should be no strain on your battery. Your lights drain your battery because the device is engaged and actively pulling a charge through its circuits. The only issue I have had with leaving the device on is that even when my car is in the garage, my phone still passes the calls through it. Makes for an awkward first 15 seconds of a conversation....

I have experienced no battery drain issues. I almost always turn it off when not in use as a precautionary measure. It has been on no longer than 24 to 48 hours without cranking a vehicle. Like I said earlier , I have never had any issues. It seems to use minimal power.

I do not know from personal experience the answer and we did not leave it plugged in at night but depending on the temperature in the car the unit holds a cool temperature very well and we often left it for 6 to 8 hours disconnected because I had a borrowed car and was afraid it might draw down the battery. We really liked the unit. It is ideal for a road trip.

I assume your qeustion is if the product can be left connected while the car is off. I'd say yes, it will turn off I think. Although I haven't tried it. But in case the 12V port inthe car stays on it may drain the car battery since it has a fan that spins when connnected to power.

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.

Yes I leave it plugged in all the time but of course when the car is off it is not providing ant power.

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

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.

It would depend on the condition of the battery. I'm guessing that if the battery is in good condition, with a full charge, it would take a couple days to discharge. I wouldnt take a chance for more than a few hours if I needed that battery. I bought the AC/DC adapter and just run an extension cord to the cooler so as not to drain the vehicle battery (if available). That little fan in the cooler doesn't draw much but it could run your battery down, just like a radio or parking lights left on.

Depends on how your car's aux plug works. In my truck, the aux plug stays powered even when the truck is off and key is removed so yes, the seat warmer will continue to heat and drain my battery in my truck. However, in my Benz, when the key is turned off, there is no power to the aux plug so it will not drain the battery. Hope this helps.
