Review conclusionWith reservationsRecommended

Only in one review: Voltage 12 V (12 V 100 W power supply).

12 V 100 W power supply: Efficiency is about 89%, but the output rectifier transistor overheats under heavy load.

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.
