Only in one review: Voltage 24 V (24 V 72 W power supply); In test 100 W (24 V 72 W power supply); Test current 6 A (HCA-72); Protection 6 A (HCA-72); Price 7 $ (24 V 72 W power supply).

24 V 72 W power supply: It reached almost 92.5% efficiency and ran steadily at 4 A; the author especially likes this version.

HCA-72: Ripple is tolerable, but electrical safety is poor and sustained in-case output is no more than 60 W.
