Hi.
Great article, and long overdue.
If you redo the AC chargers in the future, could you see if you can do a conducted emissions test on the AC side? (With a CDN and Spectrum Analyzer.) As that would interest a lot of Ham Radio guys (and gals) out here. Some of these things can be very noisy when left powered, but not connected to anything.
I have some very noisy car (12V DC powered) phone chargers too, the worst being a branded product that came with a phone!
As someone else said, after market laptop chargers vs originals would be an interesting comparison too.
Keep up the great work.
