Only in one review: Current 9 A (RK8009); Power 720 W (RK8009); Under load 81 V (RK8009); Protection 26 A (25A 600W voltage converter); Temperature rise 106 °C (25A 600W voltage converter).

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

25A 600W voltage converter: An inexpensive converter with good efficiency, but high ripple and overheating shunts at 25 A.
