Review conclusionWith reservationsRecommended

Only in one review: In test 37 W (GFA20A-12); Ripple 35 mV (GFA20A-12); No load 0.2 W (GFA20A-12); Price 6.5 $ (GFA20A-12).

HCF-24L: Efficiency is slightly higher than the 18 W model; ripple is considered acceptable, but electrical safety is poor.

GFA20A-12: The power supply showed ample power headroom, low heat and low ripple; the author recommends it.

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.
