Only in one review: Voltage 8.2 V (RBQ-8,2/45); Current 45 A (RBQ-8,2/45); In test 300 W (RBQ-8,2/45); Ripple 160 mV (LTC3780-based converter); Efficiency 98 % (RBQ-8,2/45); No load 4 W (RBQ-8,2/45); Temperature rise 90 °C (RBQ-8,2/45); Price 3.12 $ (RBQ-8,2/45).

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.

LTC3780-based converter: An interesting, powerful buck-boost converter, but it falls short of its ratings and needs improved cooling.
