Review conclusionWith reservationsRecommended

Only in one review: Voltage 48 V (48 V 2.1 A, 100 W power supply); In test 77 W (48 V 2.1 A, 100 W power supply); Efficiency 89 % (HCA-100).

48 V 2.1 A, 100 W power supply: Well built, cool-running, and low-ripple, but protection limits output to about 77 W.

HCA-100: High efficiency, low ripple and excellent voltage stability; recommended with practical output limited to 70–80 W.

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.
