D/C outlet question

[george1202]

I noticed that my phone continued charging on the car's DC socket even if the car engine has been turned off. My question is, If a leave a device (phone, GPS, etc.) plugged in the DC socket , say overnight or longer, will this drain my car battery?

The draw from a phone, GPS, or other small device should not drain your battery noticably. I've done it many times.

Thanks Tomaz. Other cars cut-off DC source when you turn the a/c key switch off.

when your phone is done charging it doesn't draw any more power
it's not like leaving lights on overnight...

Eurosport, is this the same for GPS devices as well?
