In brief: Based on review measurements: Test current: RK8009 (9 A vs. 1).
Model RK8009 Riden · 2026 Read review → SGM6130 SG Micro · 2023 Read review → Test current, A 9 1 Under load, V 81 5 Review conclusion Recommended Recommended
Only in one review: Voltage 80 V (RK8009); Current 9 A (RK8009); Power 720 W (RK8009); Ripple 50 mV (RK8009); Efficiency 98.9 % (RK8009).
RK8009: The converter showed low ripple, high efficiency and good thermal performance; its main drawback is limited input-voltage headroom.
SGM6130: After repair, the converter output 5 V and ran for about 20 minutes at a 1 A load and 26 V input without problems.
