New gear for location shooting

Recently I picked up a new piece of gear that I really enjoy using !
It's the Paul C. Buff Vagabond Mini.  It's  a lithium rechargable battery pack.
It will power up to 4 monolights !  I find myself using it even when AC jacks are available so that
I can avoid running an extension cord, but it's a real godsend when shooting in remote areas
of an industrial site for instance.  The best part is the low price, only $240 !
