Only in one review: Current 2 A (5 V 2 A power supply (10 W)); Efficiency 78 % (5 V 2 A power supply (10 W)); Protection 4.4 A (5 V 2 A power supply (10 W)); Temperature rise 117 °C (5 V 2 A power supply (10 W)); Price 4.17 $ (5 V 2 A power supply).

5 V 2 A power supply (10 W): A surprisingly good unit: it passed the tests and really delivers up to 15 W.

5 V 2 A power supply: Voltage stability is good and ripple is acceptable, but the output inductor is weak and it whines under light load.
