Only in one review: In test 50 W (ROAL Electronics mod 223E (12 V)); Under load 11.85 V (ROAL Electronics mod 223E (12 V)); Efficiency 91.6 % (ROAL Electronics mod 223E (12 V)); No load 1.8 W (ROAL Electronics mod 223E (12 V)); Protection 8 A (5 V 8 A voltage converter with four USB outputs); Temperature rise 97 °C (ROAL Electronics mod 223E (12 V)).

5 V 8 A voltage converter with four USB outputs: The converter impressed with its protections, stability, and build, though ripple is rather high.

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.
