Only in one review: Current 2 A (24 V 2 A power supply, adapter (with filter)); Power 1 W (12 V 1 W power supply); In test 3 W (12 V 1 W power supply); Test current 2 A (24 V 2 A power supply, adapter (with filter)); Under load 12.1 V (12 V 1 W power supply); Protection 2.8 A (24 V 2 A power supply, adapter (with filter)); Temperature rise 130 °C (24 V 2 A power supply, adapter (with filter)); Price 3.89 $ (12 V 1 W power supply).

24 V 2 A power supply, adapter (with filter): Suitable for about 1.5 A continuous; above that the output diode assembly overheats, and the protection threshold is too high.

12 V 1 W power supply: Despite its simple design, it delivered 3 W without overheating, with stable voltage and acceptable ripple.
