Hi Rhizome, I am not sure how much of an electronics hobbyist you are. But if you are into electronics hardware, you may have had a chance to stumble upon ladyada's store 'http://www.adafruit.com and maybe even took a look at her background at 'http://www.adafruit.com/about/. My best guess is she knows what she is talking about. As someone above mentioned, her run-of-the-mill customers are not your average Joe customer.

I believe that she is meticulous about what she sells in here store and tests them out before she makes it available to her customers. She is not rebranding the products as hers. She is just assuring her customers that she is doing due diligence prior to selling it on her site.

I like Fry's just like the next guy and they have great deals, but I don't expect to get high tech stuff there or necessarily high quality stuff. They are just another big box store but also catering to your average hobbyist. I don't know if the purchasing department there puts as much effort into checking out the products they sell.

You got what you paid for at Fry's.

I expect that even if you were that dedicated to ferreting out the best chargers, there's plenty of variation in quality when dealing with chargers that are manufactured in the hundreds of thousands and move through the supply chain very quickly. I've been very happy with my HP Touchpad chargers but that's not the universal experience.
