Only in one review: Under load 15.1 V (Sanmim GPN30E-15); Efficiency 82 % (Sanmim GPN30E-15); Price 6.76 $ (Sanmim GPN30E-15).

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.

Sanmim GPN30E-15: It handles a twofold overload steadily with moderate heating; its main drawback is the cheap terminal blocks.
