I sure hope it works for a wearable, but since it isn't an isolated
converter, there are potential problems if I try to plug it into a wall
outlet.  But so far I haven't found any need to plug it into a wall
outlet, so this will probably work just fine for me.

There are also other dc-dc converter like the one Steve Mann
recommends on his wearcomp pages (http://www.wearcomp.org/) from
PowerTrend I believe. Might want to check it out.
