Would this be helpfulI thought I saw it here but can’t find it. Anyone measured the typical and max current used by a WiiM Pro (at its 5V power input)? No line out use just WiFi in and coax out to a DAC.
Thanks! Yeah the Pro used very little current. A typical Apple 5V 1A power supply works perfectly.Would this be helpful

Yes, but we don't know how much power it consumes during the firm update. I'd be happy if someone could measure these.Thanks! Yeah the Pro used very little current. A typical Apple 5V 1A power supply works perfectly.
Shouldn’t be any more than streaming 192kHz/24bit. Certainly not more than 1A.Yes, but we don't know how much power it consumes during the firm update. I'd be happy if someone could measure these.
I measured it.a big erratum on my part...
if I pointed out in my use a fairly low consumption even with a "plus", it was just on a low resolution radio stream...but if in fact the consumption skyrockets with the resolution...
my point and the use of a simple 1A even with a "plus" becomes obsolete..
but above all invites a big precaution that I have not read it seems to me...
it is during the "subjective" tests, to clearly specify the type of resolution, see to heavily demand, at maximum, the power supply, as a precaution, only use music files that are at high resolution.....
"stress test"
sorry
;-)
I suspect it will not be that much different.a big erratum on my part...

I measured it.
Even playing 24/192 on Amazon music was up to 2W. It is a simple measurement.

Pro.pro or plus?
me too with plus, a 1A..but i just use with radio and not heavy resolution...
ahhh.. not "plus"... normalPro.
I admit I don't understand it well...One issue I could not find any info online was whether the USB C power input negotiated with the power supply the capability of the supply. I was wondering why the Wiim Pro used USB C for power instead of a typical dumb barrel connector. So I did some tests. First I connected my Apple 12W USB A Ipad power supply. I put in series a USB C meter. It read 5V, Apple 2.4A available. I put a 100W SlimQ power supply with USB C connector and it read 5V, Apple 2.4A available. Since this supply is a PD supply, it clearly negotiated with the Wiim to supply 5V and the supply advertised 2.4A was available. Why would this be important? Because the default is 5V at .5A. If you connect a 5V 2A dumb linear supply to the Wiim, the Wiim should think it provides 5V @ .5A if it follows USB C protocols and limit the amount of current pulled from the dumb linear supply to .5A, not higher. i ran some tests and could not get the Wiim Pro Plus to draw more than about .6A. Someone said they got it to pull .9A. I then took a cable, and shorted the D+ and D- lines together so according to BC1.2 protocol, the source advertises that the supply is 5V 1.5A, not .5A. I connected my linear power supply with both cables and did an A/B and did not find a situation that was much different where the Wiim Pro Plus pulled more than about .6A. I ordered a different/better monitor board to see if the el cheapo USB C monitor I was using was the issue. When I connected the linear supply with the default connector, it read that it was a Samsung protocol and when I shorted the D+ and D-, it reported that it was a QC2.0. Thats why I suspect the monitor board, because it should read DCP protocol. Will update in a week.
Well I should receive my topping p50 tomorrow and so I'll be testing this. The p50 has 2x 5V/1A usb ports, and I intend to use both at the same time.I'll try to simplify. Many people are trying linear power supplies instead of the provided noisy switch mode power supply. But linear power supplies are dumb, whereas Wiim uses a USB C power connector. A USB C power connector negotiates with the power supply the voltage and current available. So if someone uses a dumb linear power supply, it may not be communicating its capability to the Wiim to provide more than .5A current and may degrade the performance of the Wiim instead of improving it. That is what I am trying to ascertain. Halfway thru this, only conclusion so far is that the Wiim does negotiate voltage levels with the power supply. I am trying to find out if the Wiim also negociates the current level as well and uses that information to limit the current used.
