Only in one review: Current 2.5 A (24 V 2.5 A power supply); Test current 2.6 A (24 V 2.5 A power supply); Efficiency 90 % (24 V 2.5 A power supply); Protection 2.5 A (24 V 2.5 A power supply).

24 V 2.5 A power supply: Well-built and stable, but after warming up it cannot sustain the rated 2.5 A because of its protection threshold.

5 V 3 W power supply: It works without overheating, but ripple is high, output current barely reaches its rating, and short-circuit protection behaves oddly; not recommended.
