A comment to the article mentioned the audible noise some of these devices 
can generate. The article didn't get in to the amount of unwanted RF that 
can be generated by cheap devices.

I recently saw a YouTube video where a person showed a real vs. a cheap/fake 
camcorder charger. There was an AM radio playing a few feet from the 
chargers. When the cheap/fake charger was plugged in the AM radio station 
was almost wiped out by RF noise. The real charger did not affect the radio 
at all.
