Review conclusion	With reservations	Recommended

Only in one review: Power 300 W (20A Buck Converter); Under load 8.163 V (RBQ-8,2/45); Ripple 80 mV (20A Buck Converter); Efficiency 98 % (RBQ-8,2/45); No load 4 W (RBQ-8,2/45); Price 3.12 $ (RBQ-8,2/45).

20A Buck Converter: It works and is usable overall, but runs hot, falls short of the rated 36 V, and needs cooling.

RBQ-8,2/45: A genuine converter with high efficiency and high output current; at room temperature it can deliver 15–16 A without extra cooling.
