Review conclusionNot recommendedWith reservations

Only in one review: Voltage 12 V (CTG-300W-12V); Current 25 A (CTG-300W-12V); Power 300 W (CTG-300W-12V); Under load 12.216 V (CTG-300W-12V); Protection 3.2 A (24 V 2 A power supply, adapter (budget version)).

24 V 2 A power supply, adapter (budget version): The transformer overheats at 1.5 A; the realistic continuous output is about 1 A.

CTG-300W-12V: It is effectively suited to about 230–250 W; the small input capacitor and higher ripple detract from 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.
