Oops, I just discovered the Vox AC charger from
yourcharger does have detachable prongs, just a different style than those on the original Vox charger. I see that this vendor has other travel chargers complete with an assortment of foreign AC plug adaptors, so if you wanted to venture overseas, you could search around on the site and find another charger that has all the adaptors. I suppose the Vox charger doesn't include them because it has the Vox USB wiring instead.
