Any Electric DIY hobby folk out there , need help on testing usb current

[Mr Bump]

bit of an odd one , i want to test two devices i have that take usb power @ 5volts to see how much current/amps they use at max so i can spec out a linear power supply for them.
will this do just popped inline?

It's cheap enough, give it a shot and see.

yup ordered it , issue i have is some linear psu's are quite low at 5v/2amps and my tiny dac and headphone amp need to know how much they draw at max and allow some headroom

I'm not entirely sure what you're up to, but these are fun.

It shows how my devices ramp down power draw as they get fuller.

i have a similar device which iv'e had for years
the one i have is bluetooth which links to an app on my phone or pc
it works a treat and is great for measuring current draw / voltage etc as well as testing power bricks to see how close / far away they are from the real spec

mines quite old now but here is a more up to date version of it

Well I got it delivered and have plugged it in and it seems to give me the information I needed quite well
the screen is tiny but the current draw on my dac is tiny which i thought it would be only 1/10th of an amp and the draw on the headphone amp is about 1.3amp which again is excellent
so I have now ordered a nice linear psu with two outputs 1x1 amp max and 1x 2amp max @ 5volt

first image just the headphone amp
2nd with the dac included
