Abstract
In this note, we calculate all untwisted and twisted (Z/2)^n-equivariant K-groups with compact supports of real finite-dimensional linear representations of (Z/2)^n. The question was motivated by the question of D-brane charges for orbifold type II string vacua.

Comments
While we make some new observations in the present note, it came to our attention since posting the first version that the main result can be alternately deduced from a much more general theorem of Max Karoubi
