I'm hoping someone here can help. I have a 1305mAh mobile phone battery and have a 500mAh car charger. Does this mean the car charger won't charge the phone, or it will, but just take nearly 3 x the time for the wall charger
It is likely the charger is 500mA not 500mAh. With the phone not drawing current from the battery it would take about 3 hours to charge from fully flat. With the phone using power, it may take a bit longer.
