Kensington power adapter tips?

Kensington doesn't list a tip for the P7030/7130/7230 on their website and their email support states there is no tip available.

However, on the Fujitsu website I see that the same AC adapter (FPCAC45AP) is listed as being compatible for numerous models. For example it lists the Stylistic ST4120 as being compatible. When you search for this model on the Kensington website it lists tip N15. However, other models that are on the Fujitsu list are not listed as compatible on the Kensington website. I assume that this simply means they have not tested that particular model with the N15 tip.

My questions:
1. Is the Fujitsu AC adapter tip size and polarity the same for all of the models below?
2. Has anyone here tried the N15 tip for any of the Fujitsu models listed below?

Then n15 works on the p1610
