Only in one review: Current 7.2 A (Raxfly, 5 V 7.2 A); In test 34.7 W (Raxfly, 5 V 7.2 A); Under load 11.69 V (12 V 36 W power supply); Efficiency 80 % (Raxfly, 5 V 7.2 A); Protection 3.4 A (12 V 36 W power supply); Temperature rise 120 °C (Raxfly, 5 V 7.2 A); Price 11 $ (Raxfly, 5 V 7.2 A).

12 V 36 W power supply: It handles rated power well, but output capacitance is low and high-frequency ripple is elevated.

Raxfly, 5 V 7.2 A: The charger fell short of its rated current and power and overheated under sustained load.
