Review conclusionWith reservationsRecommended

Only in one review: Current 4 A (АД-12-4A); Power 5 W (5 V 1 A power supply); Under load 12.4 V (АД-12-4A); Ripple 40 mV (АД-12-4A); Efficiency 85 % (АД-12-4A); No load 0.45 W (АД-12-4A); Protection 4.9 A (АД-12-4A); Temperature rise 111 °C (АД-12-4A); Price 3.05 $ (5 V 1 A power supply).

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

5 V 1 A power supply: It performs excellently at its rated load and has the lowest ripple, but the author advises against currents above 1 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.
