Only in one review: Current 4.1 A (ROAL Electronics mod 223E (12 V)); Ripple 1500 mV (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)); Temperature rise 97 °C (ROAL Electronics mod 223E (12 V)); Price 3.77 $ (IP6518 board).

IP6518 board: The board supports QC 20 V but delivered about 40 W in testing; tests were cut short after an accidental short circuit.

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.
