Review conclusionRecommendedWith reservations

Only in one review: In test 22 W (PLF12A-15); Efficiency 80 % (PLF12A-15); No load 0.2 W (PLF12A-15); Temperature rise 97.7 °C (PLF12A-15); Price 4.17 $ (5 V 2 A power supply).

PLF12A-15: This compact supply showed good stability, low ripple and respectable efficiency; the author recommends it.

5 V 2 A power supply: Voltage stability is good and ripple is acceptable, but the output inductor is weak and it whines under light load.

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.
