Only in one review: Voltage 12 V (12 V 10 W power supply); Current 10 A (12 V 10 A power supply); Power 10 W (12 V 10 W power supply); Under load 11.95 V (12 V 10 W power supply); Temperature rise 118 °C (12 V 10 A power supply).

12 V 10 A power supply: Ripple is very low, but components overheat during sustained 10 A operation; the author advises limiting it to 8–9 A.

12 V 10 W power supply: It sustains nearly twice its rated power, but ripple is high and overcurrent protection is set too high.
