Review conclusionNot recommendedRecommended

Only in one review: Current 0.25 A (HLK-PM12); Price 2.32 $ (HLK-PM12).

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.

HLK-PM12: The author liked the supply: it was stable, survived an overload, and reached 55 °C at 400 mA.

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.
