Review conclusionWith reservationsRecommended

Only in one review: Under load 4.93 V (5 V 20 A power supply (100 W)); Protection 24 A (5 V 20 A power supply (100 W)); Temperature rise 135 °C (5 V 20 A power supply (100 W)).

5 V 20 A power supply (100 W): Well assembled, but effectively a 75 W unit; the output inductor overheats at full power.

MN-100W12V: Despite a counterfeit input capacitor, it has low ripple, good construction, and delivers its rated power and more.

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.
