Review conclusionWith reservationsRecommended

Only in one review: Voltage 5 V (5 V 10 W power supply); Power 10 W (5 V 10 W power supply); In test 15 W (5 V 10 W power supply); Ripple 300 mV (5 V 10 W power supply); Efficiency 78 % (5 V 10 W power supply).

12 V 10 A power supply: Ripple is very low, but components overheat during sustained 10 A operation; the author recommends 8–9 A instead.

5 V 10 W power supply: A decent supply delivers up to 15 W, though a lower protection threshold and an output filter would help.

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.
