record peak power draw for multiple devices

I have about 10 or so devices I need to know the individual peak power draw for in order to spec for a power supply/distro that i'm having made. what would be a reliable way to do this?

So far I have been using a plugin home energy monitor and just watching the watt readout as the device is powered under normal usage but i'm not sure if this can accurately report peaks. I was hoping to have something that i can show whatever the peak draw was over a usage of half an hour or so, one that i didn't have to just stare at until i noticed a peak..

I have a multimeter but i was hoping to find a way around striping back the cable on each device's wall wart ac adapter to get the readings. is there something inline that would do the job?
