Only in one review: Power 300 W (20A Buck Converter); Under load 48 V (Boost converter up to 400 W); Efficiency 96 % (Boost converter up to 400 W); Temperature rise 106 °C (20A Buck Converter); Weight 60 g (Boost converter up to 400 W).

Boost converter up to 400 W: It works and delivered up to 333 W, but has high ripple and may fail if the input voltage sags.

20A Buck Converter: It works and is usable overall, but runs hot, falls short of the rated 36 V, and needs cooling.
