Only in one review: Current 8.3 A (Ultra-compact 100 W, 12 V, 8.3 A power supply); In test 60 W (FSA-12V 100W); Under load 11.81 V (FSA-12V 100W); Efficiency 89.5 % (Ultra-compact 100 W, 12 V, 8.3 A power supply); No load 0.05 W (Ultra-compact 100 W, 12 V, 8.3 A power supply); Protection 7.2 A (Ultra-compact 100 W, 12 V, 8.3 A power supply); Weight 94 g (Ultra-compact 100 W, 12 V, 8.3 A power supply).

Ultra-compact 100 W, 12 V, 8.3 A power supply: Very compact and powerful for its size, but it falls short of 100 W and has large spike ripple.

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.
