Some great info on why phone/USB charger quality can vary immensely. This guy tests a bunch of them, takes them apart, and does those cool oscilloscope tests on them. I never new it but there is a ridiculous quality difference between generic chargers and those made by Apple, HP, etc.
Also some tests done on Powerbanks http://goughlui.com/?p=8022 (Probably should be in the battery forum? Whatever.)
Very interesting reading!
Thank you for posting.
Wow amazing article. What about safety? In the news there has been a story going around about a woman who was electrocuted from a usb charger. I’m thinking about getting one but I want to be sure it’s reliable and safe. This one this guy reviews seems ok.

If you want to see test on a couple of other usb chargers and power banks, check my website. I do the same kind of tests.
