no, it actually works directly off of your phone's power. but it does have a spot where you can plug a universal mini usb charger in if you would like to charge it independently.
i don't know. I can't find any markings for a brand. I threw out the packaging a long time ago, and then decided I didn't need it. Sorry, I know that doesn't help.
ok, no worries. I have definitely had that happen a lot. Usually you can tell when someone has only stock photos, isn't responding to comments, or by their feedback. But mine is definitely legit :) I ship out in 1 business day always and always provide tracking.
