Only in one review: Power 6 W (3A-064WU12); Protection 11 A (EPP-100-12); Temperature rise 118 °C (3A-064WU12).

EPP-100-12: The PSU performed well, delivering up to 7.5 A for an extended test without cooling, though brief ripple spikes reached 175 mV.

3A-064WU12: These branded 12 V supplies are generally good, holding voltage up to 0.9 A, but heat up substantially at that load.
