Common size for those cylindrical power plugs? Need an adapter.

[fuzzybabybunny]

So I've got an Asus laptop that uses a 3.0mm x 1.1mm power plug (just the straight hollow cylinder, no pin in the middle).

I want to get a portable battery such as this:

It can jump a car, charge USB, and since it's 19V it can also charge my laptop.

I have a feeling that the included power plugs *won't* include one for my Asus, so I need to find an adapter for a common sized plug.

Common plug in (female), Asus plug out (male).

One reviewer posted pics of the tips and it looks like there are 4 sizes of barrel tips included and the largest one looks pretty big. It has green plastic ring on it. The others look like the typical 2.5mm barrel.

I went to the store (I'm in Australia) and they had these batteries:

http://www.amazon.com/Zek-30000mAh-...459516011&sr=1-75&keywords=jump+start+battery

None of them had the tip I needed, so I don't want to just go off pictures. Unless the package explicitly states it has a 3.0mm x 1.1mm plug (none of them state the sizes of their plugs) I want to get an adapter as a precaution.
