One thing though ... the powerleads on all my "box" style chargers are the same, so the chargers can use the same power lead. The cigar and pipe chargers are a completely different design and have the pins that plug into the socket built into them.
I have a 4 way power board with individual swithes on each outlet, two are used for the cigar and pipe charger, the other two have leads which I use with the other 4 chargers I have now, change them as I need to use them.
