Only in one review: Protection 2.8 A (24 V 2 A power supply, adapter (with filter)).

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.

5 V 2 A power supply with microUSB plug: Works acceptably up to 1.5 A, but voltage sags above that and it can interfere with some touchscreens.
