Review conclusion	With reservations	Recommended

Only in one review: Current 40 A (RBQ-31251); Power 45 W (IP6518 board); In test 40 W (IP6518 board); Test current 3.6 A (IP6518 board); Under load 20 V (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.

RBQ-31251: A genuine converter with a heatsink; the author estimates it can deliver 20–25 A without additional cooling.
