— the second version of Qualcomm's Quick Charge technology. Initially, it was used in devices with Snapdragon CPUs, but later it was introduced in models with CPUs of other manufacturers - Samsung in particular. One of the main differences from the previous version 1.0 was that the operating voltage is not limited to the standard 5 V — the charger is capable of delivering 5 V, 9 V and 12 V, which made it possible to increase the maximum charging power to 18 W (against 10 W in version 1.0).
