This power supply unit I bought for my Samsung Galaxy Note 3, because I needed a power supply on the go, which loads with a charging current of 2 amps. Each Universal AC adapter charges only 1 amp, which also is sufficient for most devices. But takes far too long for the grade 3 (also Galaxy S4 and S5). The power supply conforms exactly to what was also the factory here. More can not be expected. My Recommendation *****
