Only in one review: Efficiency 84.5 % (Desktop 36 W 3 A).

Desktop 36 W 3 A: It delivers the rated 3 A, but with little thermal headroom; overcurrent protection is set too high and there is no thermal protection.

12 V 3 A power supply, adapter: After the revisions it runs without overheating even at 3.2 A, with acceptable ripple and electrical safety.
