Review conclusionWith reservationsRecommended

Only in one review: Current 20 A (5 V 20 A power supply (100 W)); In test 60 W (FSA-12V 100W); Efficiency 72 % (5 V 20 A power supply (100 W)); Protection 24 A (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.

FSA-12V 100W: It runs stably at about 60 W with acceptable ripple and temperature; the author considers it good if treated as a 60 W supply.

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.
