Car Phone Charger Battery Drain

But unless you re desperate charging your iphone during your commute might be a big mistake.

Car phone charger battery drain.

Avoid car battery drainage. It s plugged into a live outlet 24 7. The blinking stopped after i unplugged the charger. In most cases it s usually down to the cable you are using.

At first it may seem harmless to plug your phone into your car s usb port. If the car battery is old it may not be holding a full charge any more either. Even faster if it s cold like it has been. So if you had a 100ah car battery and your phone s battery was 1 8ah which is equal to 1800mah a completely dead handset would pull less than 2 of the charge out of your vehicle.

If charging maintaining a typical 1 5ah cell phone battery drains your 80ah service battery the float current for my cell phone charger in the car is on the order of 2ma. A car battery holds around 800 watt hours of power. And by the way here s how. This must be an older truck.

So depending on phantom load of the charger it could drain the battery enough that it cannot start the car or even completely drain it. Even when it is not charging anything leaving the phone charger plugged in may drain the car battery and may deplete its power if the engine is not running which could leave you stranded or make for an inconvenient morning. In my experience this is usually the main issue. To prevent your car phone charger from draining your car battery you should unplug your charger from the power source when it is not in use.

If the car is turned off just as with the lights inside the car the cell phone charger is drawing power from the car s battery. Leaving the charger plugged in when not charging a cell phone may also drain the battery s power but this will be a slower drain on the battery than if charging a phone. When a battery gets old and you are online with the screen on the battery will slowly lose charge becaus. However there are other actors that come into play like your charging port and actual device software.

It s hard to say at this moment in time as there are many reasons as to why this may be happening.
