Only in one review: Under load 12.4 V (АД-12-4A); Efficiency 85 % (АД-12-4A); No load 0.45 W (АД-12-4A).

АД-12-4A: It has power headroom and low ripple, but an electrical-safety issue remains.

12 V 5 A power supply: Well-built and stable, delivering up to 5.5–6 A depending on temperature; the author considers it a good unit.
