Only in one review: 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); Temperature rise 95 °C (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.

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