It dynamically adjusts voltage and current to deliver optimal charging speeds for your iPhone. PD technology can provide up to 20W of power, which is the maximum supported by iPhones for fast charging. This makes it a game-changer for users who need quick battery top-ups.

Minimum Wattage Requirements for iPhone Fast Charging

To achieve fast charging on your iPhone, you need a charger that delivers at least 18W of power. iPhones from the 8 series and later support fast charging, but the actual speed depends on the charger's wattage.
