Xiaomi Mi4’s charger’a Amp rating is 5V-2A、9V-1.2A、12V-1A, specially designed for Xiaomi Mi4


While Oppo find 7  can output 4.5 Amps – more than double the typical amperage, and the  4.5 Amp charger isn’t the only thing to thank,  as in fact, a large portion of the impressive fast-charging skills of the Oppo Find 7 lie in its battery.

Let’s plug both of the device into the USB charger, they all have zero power at this moment.

    The upcoming Galaxy Note 4 also has this feature, however Samsung is not using Qualcomm’s solution but rather their own innovation.

      It will take Oneplus One 5-6 hours to achieve full charge, so Oneplus One does not have fast charging:)
