Review conclusionRecommendedWith reservations

Only in one review: Voltage 12 V (12 V 72 W power supply); Current 6 A (HCA-72); Efficiency 83.5 % (HCA-72); Price 7 $ (12 V 72 W power supply).

12 V 72 W power supply: A well-built compact PSU, but it overheats during sustained 6 A operation without airflow.

HCA-72: Interference is absent and ripple is tolerable, but the author advises limiting load to 55–60 W because of heat and poor safety.

Figures were taken from the review text and checked against the quoted passages. Measurement conditions differ between reviews, so read the reviews yourself before buying. Prices at the time of review.
