The PROCharge USB-C 30W PD (Power Delivery) home charger can charge USB-C compatible devices up to 4 times faster than most conventional chargers. USB-C PD is a fast-charging technology, supported by certain iOS and Android devices and most laptops that use PD charging technology. It delivers much higher levels of power than standard charging. Furthermore, these chargers use PPS charging technology, which constantly monitors the level of power that is sent to the device being charged to detect the maximum power that a certain device can handle and then adjusts the power level accordingly. This protects your device by ensuring that it will not overheat or be damaged during charging.
