Is Fast Charging Technology Safe To Use? 

To address safety concerns for high-power charging, Realme representatives have introduced the "AirGap" voltage transformer, designed to isolate high voltages from smartphone batteries during electrical faults, such as circuit breakdowns, to prevent damage.

This transformer uses "contact-free electromagnetic conversion" technology. It reduces the voltage to 20 volts, thereby safeguarding battery life and ensuring the fast charger maintains a 93% power efficiency while charging.
