Only in one review: Voltage 12 V (ZC822); Current 2.5 A (ZC822); Power 27 W (ZC822); Under load 12 V (ZC822); Efficiency 97.4 % (WZ5005); Protection 2.4 A (ZC822); Price 5.45 $ (ZC822).

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

ZC822: An inexpensive board with broad protocol support, but output power is limited to 27 W.
