3, if the long-term use of non-standard output voltage\/current power supply to charge the phone, the impact on the battery is difficult to estimate. Insufficient voltage\/current will make the charging time longer, and it is difficult to full, the voltage and current are too high, easy to overcharge and lead to a decline in battery life, and may damage the phone. Output voltage and current value data from the original charger. Usually charging, it is best to use the original charger, as little as possible to use third-party power
How many volts and amps is the Apple fast charge?
