Jim,
    They are called Isotips. The are very good but you have to be careful 
sometimes the tips can short out causing overload on the batteries which 
make a mess. But other than that, they are very reliable.

Years ago I had a portable soldering iron that had a conventional tip
and an internal rechargable battery.  It was about the same size as
the "cold heat" iron, but it was a conventional, battery powered
soldering iron and it worked GREAT.  It came with a charging stand and
I never ran it down.  Dont know where it is now...lost in the garage I
suppose.
