Only in one review: Voltage 12 V (ROAL Electronics mod 223E (12 V)); Current 4.1 A (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 5 A (SW3516 board (marking erased)); Temperature rise 97 °C (ROAL Electronics mod 223E (12 V)); Price 3.6 $ (SW3516 board (marking erased)).

SW3516 board (marking erased): An inexpensive board that works well, but has noticeably higher ripple and cheap capacitors.

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.
