Only in one review: Efficiency 84 % (Sealed 36 W 3 A); No load 0.5 W (36 W, 12 V 3 A power supply).

36 W, 12 V 3 A power supply: Works for low-power, undemanding loads, but the author says he would not buy it himself.

Sealed 36 W 3 A: Protection is set correctly and overheating is not an issue, but ripple is high—up to 700–800 mV at low frequency.
