Review conclusionRecommendedWith reservations

Only in one review: Current 3 A (12 V 3 A power supply, adapter); Under load 11.69 V (12 V 36 W power supply); Temperature rise 88 °C (12 V 3 A power supply, adapter).

12 V 3 A power supply, adapter: After the revisions it runs without overheating even at 3.2 A, with acceptable ripple and electrical safety.

12 V 36 W power supply: It handles rated power well, but output capacitance is low and high-frequency ripple is elevated.

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.
