Only in one review: Voltage 5 V (5 V 2 A power supply); Current 10 A (12 V 10 A power supply); Power 10 W (5 V 2 A power supply); Protection 10.6 A (12 V 10 A power supply); Temperature rise 118 °C (12 V 10 A power supply); Price 4.17 $ (5 V 2 A power supply).

12 V 10 A power supply: Ripple is very low, but components overheat during sustained 10 A operation; the author advises limiting it to 8–9 A.

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.
