Only in one review: Voltage 80 V (RK8009); Current 9 A (RK8009); Power 720 W (RK8009); Under load 81 V (RK8009); Efficiency 98.9 % (RK8009); Temperature rise 97 °C (Two-port QC converter).

RK8009: The converter showed low ripple, high efficiency and good thermal performance; its main drawback is limited input-voltage headroom.

Two-port QC converter: Recommended, but it has high output ripple; during sustained load the chip reached 95–97 °C.
