Only in one review: Efficiency 98 % (UPS-1228-12); Price 40 $ (UPS-1228-12).

UPS-1228-12: The board showed high efficiency and exceeded its rated power, but it is expensive and has an awkward auto-start behavior.

XL4016E1 buck converter, up to 12 A: Delivers up to 10 A with low ripple, but gets quite hot and has poor build quality; the 20 A version is a better buy.
