Only in one review: Voltage 12 V (ROAL Electronics mod 223E (12 V)); Current 4.1 A (ROAL Electronics mod 223E (12 V)); Power 50 W (ROAL Electronics mod 223E (12 V)); In test 50 W (ROAL Electronics mod 223E (12 V)); Under load 11.85 V (ROAL Electronics mod 223E (12 V)); No load 1.8 W (ROAL Electronics mod 223E (12 V)).

WZ5005: Good efficiency and low ripple, but the converter is underdeveloped, with dangerous voltage spikes and other issues.

ROAL Electronics mod 223E (12 V): It runs steadily and briefly delivers 50 W, but ripple is high and calls for an output LC filter.
