I assure you that just because two adapters look the same do not have any relation to the insides. (After all, counterfeit Apple adapters look the same as genuine ones, but you wouldn't think they are the same on the inside after reading this article.) The black plug casing is a common molding style used by many factories - but its the electronics inside that count :) The best way to know if they are identical is to look for the UL certificate number, those are unique to each design.

I can assure you that as a run-of-the-mill customer, I will likely never check a UL code. I don't know if you get your casings from the same place, putting your own electronics inside, but I feel that if you want to trade on your identity as a purveyor of quality products you're going to have to look at least a little different from bad products. To borrow and twist a line from Seinfeld, "Adjacent to trash, is trash."

I did make the mistake, though, so sorry about that.

ladyada does not manufacture that charger; the website offers it, along with other general-purpose knickknacks, to compliment the main offerings- DIY electronics kits. This last bit is significant- ladyada's run-of-the-mill customer is not going to be your standard Joe looking for a charger for his cell phone.

I was traveling in China and picked up a charger that looks exactly the same from some street vendor. When it comes to cheap, no-name accessories, no one is going to spend money designing custom casing.
