Of course if you leave your car sitting for a month it s likely that the battery will get drawn down. The digital clock in your car takes more power. Changing a new battery is the right choice for you by going to the trustful garage. I have a 12v charger that is connected to a phone dock with an integrated micro usb connector.

If it is the original charger that came with the phone then the charger might be faulty or the current is not enough. If the phone is old then the battery is on it s way to the grave. It ll be because things like the car s computer and evaporative emissions system draw power even when the car is parked. This is related to is it okay to keep a usb charger plugged into the cigar lighter.

But that won t be from the led lights on your charger. Buy yoursef a 5 volt 2 1 amp output usb wall charger that wi. The power draw of just the charger would be so small that you d have to leave your car parked for weeks for it to make any difference. The difference between this and the linked post is that there is an led on the 12v plug that lights when power is supplied.

Here s why your car battery keeps draining. If you have a gps or something else plugged into it and turned on then yes after a day or two it could conceivably drain your car s battery.

But even with nothing connected the usb charger will still draw some standby current. That means when the car is sitting parked with the engine off the usb charger is still drawing current.
