Amazon also has something called Brand Registry. Essentially, if you can prove you own a brand, you can prevent other sellers from selling the same item. That's how most larger brands protect their listings.
EDIT: Or Anker for that matter. Anker is a better example because their main business is chargers/batteries, so the should care a lot about branding and making sure there are no fake chargers under their name.
That's pretty much it – no power to limit other sellers.
