Only in one review: In test 77 W (48 V, 2.1 A, 100 W (standard model)); No load 0.2 W (48 V, 2.1 A, 100 W (track)).

48 V, 2.1 A, 100 W (standard model): Well built and runs cool, but its protection limits practical continuous power to about 75 W.

48 V, 2.1 A, 100 W (track): A compact supply with honest output and low heating, but its protection trip current is much too high.
