Does using a sat nav or phone in car charger drain the car battery?
Boomshanky asked:
Will using a in car charger whilst driving on the motorway to charge my sat nav unit drain my car battery badly? Like wise would using a in car phone charger also drain my car battery significantly?

Thanks!
it doesnt drain your battery, unless you have an electric car which i doubt, it uses gasoline to charge your whatever
No. The sat nav and/or phone won’t use much current anyway, and the battery is constantly being charged while you drive.
why do u care? if it did dont you think you’d see dead cars everywhere?
The only way the Satnav or the mobile charger would drain the battery would be leaving them connected for several days (if your cigarette lighter won’t go off when you take the key out). These king of gadgets have a very low consumption around 0.5 A each in full operation.
If you’re driving, the alternator (the battery charger of the car) will keep the charge of the battery. Note that the alternator is build in way to keep the battery charged even when you have the lights on, air conditioner on, radio/CD, fog lights, etc.
If you’re having problems with your battery, better to have it checked by a garage, could be that the battery is getting old and does not hold the charge anymore.
No only if you charge things whilst the engine is switched off .a car battery is charged by the alternator while the engine is running using additional items will not use more power than can be charged so as long as your battery is in good condition there should be no problem.A car battery lasts 3 to 5 years then needs replacing
All of your car’s electrics take power from the battery and each one makes you use more fuel; it’s not free.
So if your engine is not running then the battery would drain.
No more than using the radio, the headlights or the air-con.
Remarkably, modern cars are actually designed to have things plugged into their power outputs. Incredible, isn’t it?
