Car Charger Power
If i leave the car charger on but the phone not connected does it consume power from the car or harm it ?

how about the the mobile charger at home does it also comsume power if connected to main power and phone not connected to it?

no , no & no – unless it has an led that lights when no phone is connected to it – then the answers would be yes, yes and yes
