Review conclusionWith reservationsRecommended

Only in one review: In test 100 W (24 V 72 W power supply); Test current 7 A (QS-72-12); Under load 11.31 V (QS-72-12); No load 0.5 W (QS-72-12); Protection 8.5 A (QS-72-12); Price 7 $ (24 V 72 W power supply).

QS-72-12: Fairly decent, but 6 A causes overheating; the author sees about 4.5–5 A as the practical limit.

24 V 72 W power supply: It reached almost 92.5% efficiency and ran steadily at 4 A; the author especially likes this version.

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.
