Review conclusionRecommendedWith reservations

Only in one review: In test 18 W (HCF-18L); No load 0.1 W (QS-18-12).

QS-18-12: A decent supply, but the author recommends keeping continuous load to 15 W.

HCF-18L: Delivers its rated power with acceptable ripple and stability, but has poor electrical 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.
