Hi, I have an HDMI switch 4 input x 1 output. Its original power supply was 5V DC, 1A output (input was AC 100-240V 50Hz 0,15A) , Since this power supply was destroyed, I used another new Power Supply which has DC 5V 2A output (input is 100-240V AC 50/60 Hz 0.55A ). It seems to work fine untill now but I am not sure if it will have any problem because I give power with 2 A DC. Will it work ok? Thank you.
