The USB charger allows for charging USB devices from a wall outlet. Thanks to the Qualcomm Quick Charge 3.0 compatible technology, the charging voltage is directly adjusted to the device, enabling up to 4 times faster charging for supported devices. The Qualcomm Quick Charge 3.0 technology is 38% more efficient than the previous version 2.0. The charger detects the nominal voltage through an intelligent chip and increases the charging voltage depending on the device's charge state. This allows for a more efficient charging process. Power is supplied via mains voltage sockets. Devices without Qualcomm Quick Charge functionality are supplied with the standard charging voltage of 5 V/DC. Thus, it is compatible with all devices, ensuring you are prepared for the future. Special feature: Qualcomm Quick Charge 3.0.
