Yep, depending on the pi. Pi 3B requires 2A, 4B+ pi foundation says 3.5A. add to that any USB devices and what they pull up to another amp, then you need a powered hub beyond that

I had hoped that device would service all my usb needs, but I believe a pi needs 2-3 amps?
I think a 7805 puts out 1.5 amps his device puts out 15. Does he need 15 amps?
If you have enough power... Use an7805
That sure is quiet even if it wastes some power in heat...
Sure its possible to make a switcher quiet... Meanwell psu are really good... But for shortwave i would additionally add some filters and ferrites.. If a switcher used...
Or use 7805... Grin
