Current is limited to 1A because that's what the supply is rated for. Good supplies will actually provide 1A, or a little more. Cheap ones might not provide 1A reliably.If it is rated for eg. 1000mA at 12V (12VA), may I assume that it can source 4A at 3V for example?
Or the limit remains 1A due to wire thickness?
I don't have the one in the picture, was just an exampleBE CERTAIN the voltage is set to 5 volts before plugging it in to a USB connector.
Actually the label in the pictur above saysThe label says 3A max for 5V to 12V.
You stated succinctly in your initial post that the picture wasn't what you had.I don't have the one in the picture, was just an example
And then you said:I have one of those multi voltage power supplies, similar to this
If it is rated for eg. 1000mA at 12V (12VA), may I assume that it can source 4A at 3V for example?

Wire gauge would only be a limiter in poorly designed power supplies. I bought 4 of them from Ali Express. They have built-in volt meters that don't provide accurate readings if any significant current is being drawn.Probably due to wire sections or other components current capability
