will not
iphone car charger will not have any impact, because the car charger voltage is not as large as the original voltage, so don't worry.
12V car power supply through the DC-DC power converter into 5V, you can charge the phone. Another way is to first use the inverter to become 220V, and then use the mobile phone charger to charge the mobile phone.
At present, the mobile phone on the market is 5V charging interface, if directly connected to the 12V vehicle voltage will burn the mobile phone circuit. Because the vehicle power supply environment is relatively bad, the voltage fluctuation is relatively large, and the environmental temperature difference is also very large, so the purchase of 12V-5V converters must pay attention to the purchase of good quality and guaranteed big brand products. Avoid using cheap copycat products that can damage your phone or even cause a fire.
It doesn't hurt the phone, it doesn't hurt the car battery. First of all, most Apple mobile phones have a fast charge function, which can withstand the input current of about 5a~10a, but the output of the car charger is generally not greater than 4a, so this current is able to withstand the charging of the Apple mobile phone, and it will not harm the mobile phone battery. At the same time, the electricity required by the Apple mobile phone will not be greater than 0.5a, so the vehicle battery. It won't hurt.
Yes, it will do no harm to the lithium battery.
1, the iPhone uses lithium polymer batteries, there is no memory effect, so there is absolutely no need to charge and discharge each time thoroughly (that is, at any time you want to charge).
2, lithium battery after each charge and discharge cycle, the power will be reduced a little, about 400 charge and discharge cycles will be reduced to 80%. The so-called a charge and discharge cycle refers to the complete full and discharge, that is, if you use 20% of the electricity is full, to repeat 5 times before a charge and discharge cycle.
Apple car charger will affect the life of the Apple phone battery itself, Apple battery is relatively poor, so it is not recommended to use car charging
