Review conclusionWith reservationsWith reservations

Only in one review: Under load 12.28 V (АД-12-2A); Efficiency 76 % (АД-12-2A); No load 0.5 W (АД-12-2A).

12 V 2 A power supply: It overheats at 2 A; the author estimates its realistic continuous output at about 1.5 A.

АД-12-2A: Regulation is excellent, but the output diode gets hot at 2 A; for continuous use, limit current to 1.7–1.8 A.

Figures were taken from the review text and checked against the quoted passages. Measurement conditions differ between reviews, so read the reviews yourself before buying. Prices at the time of review.
