Review conclusionRecommendedNot recommended

Only in one review: Current 3 A (AD-12-3A); Power 3 W (5 V, 3 W power supply); Efficiency 84 % (AD-12-3A); No load 0.45 W (AD-12-3A).

AD-12-3A: It sustains 3.5 A with modest temperatures and low high-frequency ripple; the author notes a safety concern.

5 V, 3 W power supply: It works and stays reasonably cool, but ripple is high, protection is erratic, and output barely reaches its rating.

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.
