Review conclusionWith reservationsWith reservations

Only in one review: Voltage 12 V (1204).

1204: It regulates well but has elevated ripple; the author recommends about 3–3.5 A for continuous use.

1205: Its performance is close to the 1204, but it runs hot under load; continuous current should be no more than 4 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.
