Only in one review: Voltage 60 V (RK6018); Current 18 A (RK6018); Power 1080 W (RK6018); In test 940 W (RK6018); Under load 52 V (RK6018); Protection 4 A (RK6018); Price 57 $ (RK6018).

RK6018: High efficiency, low losses and ripple; the author dislikes the odd behavior of SCP.

WZ5005: Good efficiency and low ripple, but the converter is underdeveloped, with dangerous voltage spikes and other issues.
