Yes, i also have the same one.
BTW. those old Standard Laptop Chargers/ Power Supplies will also work, if you have one of those on hand. They are usually 19V and used to come with the Same Plug. Newer Laptops now have a lot of different connectors, but the Same one like on the 2.1 was used on a bunch of Brands for a while.
This is the original one, but if you ever have to use anything else, just make sure it is 17-20V, can deliver 40W of power or more and has an 5.5/2.5mm barrel jack, positive tip. Anything with those Ratings will work, if you happen to not have the Original one on hand for some reason.
